Help with Streaming and Chunk Processing for Large JSON Data (60 GB) from Kenna API

[Asif Ali Hirekumbi via Python-list]

Dear Python Experts,

I am working with the Kenna Application's API to retrieve vulnerability
data. The API endpoint provides a single, massive JSON file in gzip format,
approximately 60 GB in size. Handling such a large dataset in one go is
proving to be quite challenging, especially in terms of memory management.

I am looking for guidance on how to efficiently stream this data and
process it in chunks using Python. Specifically, I am wondering if there’s
a way to use the requests library or any other libraries that would allow
us to pull data from the API endpoint in a memory-efficient manner.

Here are the relevant API endpoints from Kenna:

   - Kenna API Documentation
   <https://apidocs.kennasecurity.com/reference/welcome>
   - Kenna Vulnerabilities Export
   <https://apidocs.kennasecurity.com/reference/retrieve-data-export>

If anyone has experience with similar use cases or can offer any advice, it
would be greatly appreciated.

Thank you in advance for your help!

Best regards
Asif Ali

Weak Type Ability for Python

[Ali Mohseni Roodbari]

Hi all,
Please make this command for Python (if possible):

>>> x=1
>>> y='a'
>>> wprint (x+y)
>>> 1a

In fact make a new type of print command which can print and show strings
and integers together.

Sincerely yours,

Re: Convert MBOX thunderbird to PST outlook

[Kr4ck ALI]

I have about 1000 mailbox to migrate and all are store in local on each
computers.
I know PST files store contacts, calendar, tasks... So, I think that is
possible to build a PST file with python to integrate the differents items
(emails, calendar, tasks,...) from thunderbird files.

Convert MBOX thunderbird to PST outlook

[Kr4ck ALI]

Hello,

I have to migrate multiple mailbox (emails, contacts, calendar, tasks) from
thunderbird to outlook Office 365.
I plan to export all items from thunderbird files (.mbox for email, .sqlite
or .sdb for calendar, .mab to contact) to PST files and import each PST
files to Office 365.
I know it's a tedious task ... But I know that nothing is impossible !
I found this script very helpfull to begin :

#!python3
import os, sys
import gzip
import mailbox
import urllib.request
import win32com.client

dispatch = win32com.client.gencache.EnsureDispatch
const = win32com.client.constants
PST_FILEPATH =
os.path.abspath(os.path.join(os.path.expandvars("%APPDATA%"),
"scratch.pst"))
if os.path.exists(PST_FILEPATH):
os.remove(PST_FILEPATH)
ARCHIVE_URL =
"https://mail.python.org/pipermail/python-list/2015-November.txt.gz";
MBOX_FILEPATH = "archive.mbox"

def download_archive(url, local_mbox):
with gzip.open(urllib.request.urlopen(url)) as archive:
with open(local_mbox, "wb") as f:
print("Writing %s to %s" % (url, local_mbox))
f.write(archive.read())

def copy_archive_to_pst(mbox_filepath, pst_folder):
archive = mailbox.mbox(mbox_filepath)
for message in archive:
print(message.get("Subject"))
pst_message = pst_folder.Items.Add()
pst_message.Subject = message.get("Subject")
pst_message.Sender = message.get("From")
pst_message.Body = message.get_payload()
pst_message.Move(pst_folder)
pst_message.Save()

def find_pst_folder(namespace, pst_filepath):
for store in dispatch(mapi.Stores):
if store.IsDataFileStore and store.FilePath == PST_FILEPATH:
return store.GetRootFolder()

download_archive(ARCHIVE_URL, MBOX_FILEPATH)
outlook = dispatch("Outlook.Application")
mapi = outlook.GetNamespace("MAPI")
pst_folder = find_pst_folder(mapi, PST_FILEPATH)
if not pst_folder:
mapi.AddStoreEx(PST_FILEPATH, const.olStoreDefault)
pst_folder = find_pst_folder(mapi, PST_FILEPATH)
if not pst_folder:
raise RuntimeError("Can't find PST folder at %s" % PST_FILEPATH)
copy_archive_to_pst(MBOX_FILEPATH, pst_folder)

My question is : Have you already make a mission like that ?

Thanks in advance !

+1

I experienced procmail and worked like a charm for me, in a case like
yours. My script was parsing emails to grab some URIs of binary
objects and queue them to be processed later.

You can easily trigger a python script and do whatever you need in
that script. If it is a long term process, you should just parse email
and use queues for the rest.

Initially the 'is' compared returned value with None, I changed the
code and it remained as is. After i have noticed this issue.

Using `is` to compare with None  is OK, isn't it?

python3 byte decode

[Ali Rıza KELEŞ]

Hi,

Yesterday, while working with redis, i encountered a strange case.

I want to ask why is the following `True`

```
"s" is b"s".decode()
```

while the followings are `False`?

```
"so" is b"so".decode()
"som" is b"som".decode()
"some" is b"some".decode()
```

Or vice versa?

I read that `is` compares same objects, not values. So my question is
why "s" and b"s".decode() are same objects, while the others aren't?

My python version is 3.6.3.

Thanks.

Python on Windows with linux environment

Hi,

I use windows regularly, however, I use linux for only my research work at 
supercomputer. In my research field (materials science) most of the scripts are 
being written in python with linux based system. Could I installed such linux 
based python on my window 7? So that I can use those linux based scripts 
written in python and I can also write my own scripts/code without entirely 
changing my operating system from windows to linux.

Looking for your valuable suggestions.

this, please recommend Python version, literature, text books, websites, video 
lectures, your personnel tips, etc. In addition, you may also add some extra 
suggestions for shell script writing as well. You may recommend for both Linux

But I have to modify it to extract data into a single .dat file instead of

Thank you for your post.

 How do I convert/change/modify python script so that my data could be 
extracted according to python script and at the end it generates another single 
extracted data file instead of displaying/showing some graph? So that, I can 
manually plot the newly generated file (after data extraction) by some other 
software like origin.

AttributeError: LineLogic instance has no attribute 'probe'

Hello,

I'm quite puzzled with an error I'm having in my code.

In the class ---> LineLogic

I have the following portion of code:

def __init__(self):
  self.probe = vtk.vtkProbeFilter()

probe.SetInputConnection(line.GetOutputPort())
probe.SetSourceData(volumeNode.GetImageData())
probe.Update()

In another class ---> LineLogicTest

I had the following portion of code:

logic = LineLogic()
probe = logic.probe
data = probe.GetOutput().GetPointData().GetScalars()

When I try running the program, I get the following error:

AttributeError: LineLogic instance has no attribute 'probe'

How can I solve this error?

Why is pexpect acting funny with sendline() and expect()?

[saqib . ali . 75]

I am running Solaris 5-10, python 2.6.2 and pexpect 2.4

I have the very simple python script below which exercises the functionality of 
sending and receiving text from the shell.

My understanding is that pexepect([pexpect.TIMEOUT, x,y,z], timeout=w) will 
return the index of the match that it found *since the last time pexpect was 
called*, but if it takes longer than w seconds, it will return 0.


Here is my very simple script:


#!/usr/bin/env python

import pexpect
myPrompt = " % "

myShell = pexpect.spawn("/bin/tcsh")
print "Sending 'JUNK-0' to shell"
x = myShell.sendline("JUNK-0")
y = myShell.expect([pexpect.TIMEOUT], timeout=1)   
print "y = %s" % y
print myShell.before 
print "=" * 80
print "\n\n"
 
for i in range(2):
print "i = %d" % (i+1)
print "Sending 'JUNK-%d' to shell" % (i+1)
x = myShell.sendline("JUNK-%d" % (i+1))
y = myShell.expect([pexpect.TIMEOUT, myPrompt], timeout=10)  
print "y = %s" % y
print myShell.before
print "=" * 80
print "\n\n"



FYI, my shell prompt is "myMachine % ", however in this script I have simply 
used " % " to keep it generic.

When I run it, I see the following output: 




Sending 'JUNK-0' to shell
y = 0
JUNK-0
myMachine % JUNK-0
JUNK-0: Command not found.
myMachine % 




i = 1
Sending 'JUNK-1' to shell
y = 1
JUNK-0
myMachine 




i = 2
Sending 'JUNK-2' to shell
y = 1
JUNK-0
JUNK-0: Command not found.
myMachine 





Why do I see "JUNK-0" consistently recurring in the output? It should be 
consumed by the first myShell.expect() statement, but it keeps showing up. Why??

Why does os.stat() tell me that my file-group has no members?

that mygrp has no members???

Detect file is locked - windows

I am trying to open a file in 'w' mode open('file', 'wb'). open() will throw

How can I distinguish these two cases ? Namely, if some application has the

How to make PyDev pep8 friendly?

[Ali Zandi]

Hi,

I was trying to find a way to configure PyDev e.g. in Eclipse to be
pep8 friendly.

There are a few configurations like right trim lines, use space after
commas, use space before and after operators, add new line at the end
of file which can be configured via Eclipse -> Window -> Preferences -
> PyDev -> Editor -> Code Style -> Code Formatter. But these are not
enough; for example I couldn't find a way to configure double line
spacing between function definitions.

So is there any way to configure eclipse or PyDev to apply pep8 rules
e.g. on each save?

Re: Problem while doing a cat on a tabbed file with pexpect

[Saqib Ali]

Very good question. Let me explain why I'm not opening me.txt directly
in python with open.

The example I have posted is simplified for illustrative purpose. In
reality, I'm not doing pexpect.spawn("/bin/tcsh"). I'm doing
pexpect.spawn("ssh myuser@ipaddress"). Since I'm operating on a remote
system, I can't simply open the file in my own python context.

Problem while doing a cat on a tabbed file with pexpect

[Saqib Ali]

I am using Solaris 10, python 2.6.2, pexpect 2.4

I create a file called me.txt which contains the letters "A", "B", "C"
on the same line separated by tabs.

My shell prompt is "% "

I then do the following in the python shell:


>>> import pexpect
>>> x = pexpect.spawn("/bin/tcsh")
>>> x.sendline("cat me.txt")
11
>>> x.expect([pexpect.TIMEOUT, "% "])
1
>>> x.before
'cat me.txt\r\r\nA   B   C\r\n'
>>> x.before.split("\t")
['cat me.txt\r\r\nA   B   C\r\n']



Now, clearly the file contains tabs. But when I cat it through expect,
and collect cat's output, those tabs have been converted to spaces.
But I need the tabs!

Can anyone explain this phenomenon or suggest how I can fix it?

Changing the system clock with pexpect confuses pexpect!

[Saqib Ali]

See my code below.

I'm controlling a shell logged in as root with pexpect.

The class below has a method (startProc) which spawns a shell and
keeps it alive until told to destroy it (stopProc).

The other 2 methods in this class allow me to change the system clock
and to get the IP Address of this machine.

They all work fine except when I advance the system clock, and
then try to get the IP Address.
In that case, I get an exception because pexpect incorrectly thinks
the output it is getting from ifconfig is invalid. But it is not.
Pexpect is just confused. This doesn't happen when I move the clock
backwards. It only happens when I move the clock forward.

I believe what is going on is that internally pexpect uses the system
clock to keep track of when it receives data from spawned processes.
When I mess with the clock, that messes up the internal workings of
pexpect.

Any suggestions what I should do? I have numerous concurrent pexpect
processes running when I modify the clock. Is there anyway to prevent
them all from getting totally screwed up??

Can't I define a decorator in a separate file and import it?

[Saqib Ali]

I'm using this decorator to implement singleton class in python:

http://stackoverflow.com/posts/7346105/revisions

The strategy described above works if and only if the Singleton is
declared and defined in the same file. If it is defined in a different
file and I import that file, it doesn't work.

Why can't I import this Singleton decorator from a different file?
What's the best work around?

http://mail.python.org/mailman/listinfo/python-list

Can I get use pexpect to control this process?

[Saqib Ali]

I have a program X that constantly spews output, hundreds of lines per
minute.
X is not an interactive program. IE: it doesn't take any user input.
It just produces a lot of textual output to STDOUT.

I would like to save the output produced by X into a different file
every 5 seconds regardless of the actual content. I want one file to
contain the output from seconds 0-5, another file should contain 6-10,
etc. etc.

Can I do this with pexpect? I'm not sure I can because the "before"
argument gives me EVERYTHING upto the most recent match. What I really
need is something that will give me what was produced between the last
2 calls to pexpect.expect().

Need help with really elementary pexpect fragment

[Saqib Ali]

I want to write a pexpect script that simply cd's into a directory ("~/
install") and then runs a command from there. It should be so easy.
But even my cd command is failing. Can't figure out what the problem
is. The command line prompt is "[my machine name here] % "

Here is the code fragment:

print "Spawning Expect"
p = pexpect.spawn ('/bin/tcsh',)

print "Sending cd command"
i = p.expect([pexpect.TIMEOUT, "%",])
assert i != 0, "Time-Out exiting"
p.sendline("cd ~/install")

Here is the output:

Spawning Expect
Sending cd command
Time-Out exiting


How could I be screwing something so simple up??

Thanks Chris. That was certainly very helpful!!

So just out of curiosity, why does it work as I had expected when the

Inexplicable behavior in simple example of a set in a class

[Saqib Ali]

I have written two EXTREMELY simple python classes. One class
(myClass1) contains a data attribute (myNum) that contains an integer.
The other class (myClass2) contains a data attribute (mySet) that
contains a set.

I instantiate 2 instances of myClass1 (a & b). I then change the value
of a.myNum. It works as expected.

Then I instantiate 2 instances of myClass2 (c & d). I then change the
value of c.mySet. Bizarrely changing the value of c.mySet also affects
the value of d.mySet which I haven't touched at all!?!?! Can someone
explain this very strange behavior to me? I can't understand it for
the life of me.

Please see below the source code as well as the output.


-- SOURCE CODE --
import sets

class myClass1:

myNum = 9

def clearNum(self):
self.myNum = 0

def __str__(self):
  return str(self.myNum)

class myClass2:

mySet = sets.Set(range(1,10))

def clearSet(self):
self.mySet.clear()

def __str__(self):
  return str(len(self.mySet))

if __name__ == "__main__":

# Experiment 1. Modifying values of member integers in two
different instances of a class
# Works as expected.
a = myClass1()
b = myClass1()
print "a = %s" % str(a)
print "b = %s" % str(b)
print "a.clearNum()"
a.clearNum()
print "a = %s" % str(a)
print "b = %s\n\n\n" % str(b)



# Experiment 2. Modifying values of member sets in two different
instances of a class
# Fails Unexplicably. d is not being modified. Yet calling
c.clearSet() seems to change d.mySet's value
c = myClass2()
d = myClass2()
print "c = %s" % str(c)
print "d = %s" % str(d)
print "c.clearSet()"
c.clearSet()
print "c = %s" % str(c)
print "d = %s" % str(d)




-- OUTPUT --
> python.exe myProg.py

a = 9
b = 9
a.clearNum()
a = 0
b = 9



c = 9
d = 9
c.clearSet()

Aiswarya Rai

Aishwarya Rai Biography
Ash Ash Baby
Aishwarya Krishnaraj Rai was born on 1 November 1973 in Mangalore. Her
father Krishnaraj Rai was a marine engineer and her mother Vrinda Rai
is a writer. She has an older brother Aditya Rai who is in the
merchant navy. He also happened to co-produce Dil Ka Rishta in 2003,
which starred Ash. The family moved to Mumbai where she studied at the
Arya Vidya Mandir and later moved to Ruparel College. She was aspiring
to study architecture but that did not take off while her career in
the glamour industry took off.

Ash won the coveted Miss World crown in 2004. Soon after this she
pledged to donate her eyes after her death. She went on to become the
brand ambassador for brands like L’Oreal, Pepsi, and Coco Cola. She
struck a pose for many international magazines like TIME and was also
voted one of the most attractive and influential women by several
polls. She is the first Indian actor to be part of the jury at the
prestigious Cannes Film Festival. She has appeared in The Oprah
Winfrey Show, Late Show with David Letterman, and 60 Minutes. She was
also the first Indian actress to be replicated in wax at Madame
Tussaud’s Museum in London.

She was briefly involved with actors Salman Khan and Vivek Oberoi
before marrying actor Abhishek Bachchan, son of the iconic Amitabh
Bachchan and Jaya Bachchan. They were married in 2007. The couple have
acted together in many movies. They were seen in the latest Lux ad and
have been roped in to be part of PETA’s Lovebirds campaign.

The Rai Magic
Aishwarya began her career in the film industry with a Tamil film
Iruvar in 1997 which was a hit as opposed to her Hindi film Aur Pyaar
Ho Gaya with Bobby Deol. She won the Filmfare Best Actress Award for
her next Tamil film Jeans, which was also an entry to the Oscars. In
1999, she gained recognition in Bollywood with hits like Taal and Hum
Dil De Chuke Sanam, in which she played opposite Salman Khan and Ajay
Devgan, her role as Nandini fetching her the Filmfare Best Actress
Award.

In 2000, her Tamil film Kandukondain Kandukondain, saw a good turnout.
She took on the role of Shirley, Shahrukh Khan’s sister in Josh and
then played his love interest in Mohabbatein which won her a
nomination for the Filmfare Best Supporting Actress Award. In Hamara
Dil Aapke Paas Hai, she played Preeti Virat, a rape victim and was
considered for the Filmfare Best Actress Award. The year 2001 was a
quiet year for Ash.

Sanjay Leela Bhansali’s Devdas (2002), in which she played Paro with
Shahrukh Khan and Madhuri Dixit, was an instant blockbuster. It also
received a special screening at the Cannes Film Festival. She won the
Filmfare Best Actress award. In 2003, she acted the part of Binodini
in a Bengali film Choker Bali which was based on a novel by
Rabindranath Tagore. The film was nominated for the Golden Leopard at
the Locarno International Film Festival.

The year 2004 saw Ash in her first English film, Gurinder Chaddha’s
Bride & Prejudice, an adaptation of Jane Austen’s Pride & Prejudice.
Her performance as Neerja in Rituparno Ghosh’s Raincoat was praised.
This was followed by her second English film in 2005, The Mistress of
Spices, with Dylan McDermott of The Practice fame. Her dance sequence
Kajra Re from Bunty Aur Babli became one of the most popular tunes of
the year.

She had two films out in 2006. Umrao Jaan with Abhishek Bachchan
failed to do well while Dhoom 2 where she played Sunehri and shared a
‘controversial’ liplock with Hrithik Roshan was a big hit. In 2007,
she played Sujata opposite Abhishek Bachchan in Guru, based on the
industrialist Dhirubhai Ambani and it was successful. Provoked, which
was based on a real episode of domestic violence, won critical
acclaim. The other English film, The Last Legion, did not do so well.

Jodhaa Akbar, released in 2008, in which she acted the part of Jodhaa
Bai with Hrithik Roshan was average. The sequel to Sarkar, Ram Gopal
Varma’s Sarkar Raj, in which she plays a CEO alongside Amitabh
Bachchan and Abhishek Bachchan, is said to be one of her best
performances till date.

In 2009, Rai looked her gorgeous self in The Pink Panther 2 with Steve
Martin.

Going Strong
She was also busy shooting for Mani Ratnam’s Raavan with Abhishek
Bachchan and Endhiran with Rajnikanth in 2009. Both movies will be
released in 2010 along with Action Replay with Akshay Kumar and
Guzaarish, in which she will play Hrithik Roshan’s nurse.

Re: platform.machine(): ImportError: No module named select

[Ali H. Caliskan]

I'm using Arch Linux and the current python version is 2.6.1, so I did
create a custom python3 package by myself and tried to install it on /opt
directory. I believe it's a installation issue, because I skipped "make
test" part during compilation, which failed with some errors.

Socket Question

[Ali Hamad]

Hello All :

A socket question from a networking newbie.  I need to create
a server that:

1) receive a message from client.
2) check that message and response to it.
3) the client get the server message and send another message.
4) finally, the server receive the message and close the connection.

I have successfully done this. However, I couldn't use the same socket
to send the second message
to the server. I have googled but all the examples are only for sending
one message and receiving the response.

in my client code, I have :

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 1888))
s.send("1st message")
response = s.recv(1024)
validate(response)
s.send("2nd message")
response2 = s.recv(1024)
s.close()

However, I got the first response just fine from the server but the
second message didn't get to the server.

So, the solution I came up with is to send the 1st message, close the
socket, create new socket,
and send the 2nd message.

I came up with something like :

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 1888))
s.send("1st message")
response = s.recv(1024)
s.close()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 1888))
s.send("2nd message")
response = s.recv(1024)
s.close()

and it works !

My Question :

is it possible to send/receive from the same socket more than one message ?

Thank you for your assistance in advance,

pympi and threading in python

[Dina Ali]

Hello there

I am confused in the usage/differences of pympi and threading in python.
What I want to do it to run multiple MCMC simulations by dividing the number
of the chains I want to run on number of the processors available. Some
methods need to be synchronized/locked until some addition operation is
finished.

I will be very grateful if some one could help.

Thanks very much

I tried PyDev with Eclipse too and it's an aweful environment to me.
Auto-completion was a total failure too...

I have quick tried iPython and autocomplete seems to work pretty
decently, even if it's not same as in a GUI. Thank you very much for
your advice.

Could you let me know how do work with .py files in iPython please?
