Re: [Tutor] passing named arguments through command line
Hello,
take a look at argparse library.
---
import argparse
parser = argparse.ArgumentParser(description=My prgoram)
parser.add_argument('-y', '--y', help=Y value, required=True)
parser.add_argument('-x', '--x', help=X value, required=True)
def main(x=1, y=2):
print x
print y
if __name__ == '__main__':
args = parser.parse_args()
main(x=args.x, y=args.y)
Enjoy!

I have a function with optional arguments x, y and I would like to
pass y or z using a named variable through the command line. Inside a
python script main(y=3) would work, but I have trouble passing y=3 as
an argument in command line.
I have tried the following:
import sys
def main(x=1, y=2):
print x
print y
if __name__ == '__main__':
main(*sys.argv[1:])
-
from my terminal I get:
$ python script.py
1
2
$ python script.py y=3
y=3
2
whereas I would like the following to happen:
$ python script.py y=3
1
3
Is this doable in any convenient way?
thanks in advance!

Re: [Tutor] How can I let the Python Console display more decimal precision?
Hi, from the question you're using python 2.x you can do either: 26.0/12 (float divide by int - it retypes both to floats and gets you 2.) or at the beginning do: from __future__ import division That will activate python3 way of dividing - which gives you 2.

I don't know why the Console only returns the integer part of true result. Anyone can help me out?

Re: [Tutor] code review
Post it somewhere on github and I'll try to take a look at it. Lukas On 06/10/2014 05:51 PM, Adam Gold wrote: Hi there.

Re: [Tutor] python sockets
Hi,
fist - are you really triyng to have open 64 000 ports? ok, i suppose
you have your reasons, but this is not a good idea - you'll block most
applications that use these ports ..
The problem is with your main function -
you have PORT defined, but it is not global, it is only local, and when
you add +1 to it, next spawned process will have PORT with previous value.
either use global PORT, or have it as a parameter for the function:
main(port):
..
PORT = port
while startingPort65535:
thread.start_new_thread(setup(startingPort))
startingPort=startingPort+1

Re: [Tutor] SHA256 P2P Chat in python
Hi, I did a similar thing recently, a chat, that encrypts and signs (for authenticity) each message sent with private-pub keypair: https://github.com/lunemec/python-chat. It is not p2p, it sends messages to server, which decrypts them, encrypts with its pubkey and sends to all clients for decoding. It is just a prototype and could be done better. I wanted to have the server act only as a relay for clients to discover each other (no need for DHT) and then to forward each client's pubkey to all others. I'm not sure exactly how onion routing would be done, I suppose something similar to Tor, but how would you want to use it on chat? Lukas On 06/08/2014 09:07 AM, Danny Yoo wrote: I was wondering if it is possible to make a p2p chat application with sha256 secured onion routing in python, and if so, what functions, guides, modules, etc. would I have to look at. This is somewhat outside of the experience of many folks on this list; you might consider asking on a broader forum. I suspect it is possible, given that Bram Cohen's original bittorent was written in Python. Try asking on the main Python mailing list.

Re: [Tutor] How to create a dictionary for ount elements
Hi,
I'd suggest using different data structure for the intersect of samples
from a program.
data = {
'program1':
{
'sample1': {'TP53', 'ASD'},
'sample2': {'ASD'},
},
'program2': {
'sample1': {'ASD'}
}
}
this way you can do this:
for program in data:
program_genes = []
for sample, value in data[program].iteritems():
program_genes.append(value)
data[program]['intersection'] = set.intersection(*program_genes)
Now you have in each 'programX' sub-dictionary key 'intersection', with
intersection of
all the program genes.

So what I want to do is to use intersect between the keys recursively:
s = diz[('program2', 'sample1']
:
:
KeyboardInterrupt
In [14]: s = diz[('program2', 'sample1')]
In [15]: s
Out[15]: {'PRNP', 'TP53'}
In [16]: a
Out[16]: {'ATF3', 'PRNP'}
In [17]: s.inte
s.intersection s.intersection_update
In [17]: s.intersection(a)
Out[17]: {'PRNP'}
How can Have a intersect of all my dictionary and from ('program1', 'sample1')
vs ('program1', 'sample2')...
I want to count how many genes are common
Thanks in advance for your help!

[Tutor] looking for volunteers with testing simple python program
Hello, I changed some simple python client/server chatroom recipe to include RSA keypair based encryption and signature verification because I'm sick of someone spying on my conversations on FB and similar. Here is the code: https://github.com/lunemec/python-chat If anyone is interrested in trying the software - mostly bughunting and improvements please run these commands after downloading the source codes: cd client |openssl genrsa -out your_cert_name.pem -des3 4096 ||openssl rsa -pubout -in yourt_cert_name.pem -passin pass:yourpassword -out your_chatroom_nick.pub ## After this step, please send me your_chatroom_nick.pub file, it should have the same name.pub as you want to use in the chatroom, otherwise we can't decrypt your messages # if you don't have pycrypt, then sudo pip install pycrypto python client.py your_chatroom_nick nemec.lu 3490 your_cert_name.pem yourpassword Now we should be able to chat :) Enjoy, and please don't kill me for writing here :) Lukas | ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
