[Tutor] Seeing response from authorization page with urllib2
If I open a web page in my browser, I get a pop-up window that informs me that I need to provide authorization information. But often, in addition, that little pop-up window will give me some additional information supplied by the page itself. For example, the chromium browser pop-up might say, The server requires a username and password. The server says: x But when I attempt to get any part of an authorization-required page using urllib2.urlopen(), I immediately receive the 401 error. Even the intended object variable is left in an undefined state, so using info() doesn't seem to work. How can I get that information from the server?

Re: [Tutor] simon says
Sounds as though what is wanted in a Pythonic version of an early electronic game Simon that was marketed back in the late 70's. It was roughly Frisbee shaped although slightly larger. The top was divided into four quadrant-shaped paddles each of a different color. The game consisted of Simon generating longer and longer sequences of random color-sound flashes (each element in the sequence consisted of a momentary sound accompanied by the appropriate quadrant lighting up). After Simon had generated a sequence, the player had to duplicate it by pressing the paddles. A successful recreation of a sequence was rewarded by Simon generating a longer one, until the player finally screwed up. At that point Simon made an electronic rude noise and the device was handed on to the next player if there were multiple players. The player who succeeded in matching the longest sequence was the winner of that round. I'll bet ebay still has them for sale, and Google would get you a description that would be better than mine. -Bill Thanks Bill. I did some more searching and managed to find a few new versions on youtube with altered gameplay i guess. Here's the closest to what has been described here: http://www.youtube.com/watch?v=agUABjGAJww thanks to everyone ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

The HTTPError object has the information you want: url, code, reason, headers -- along with the methods info, read, readline, and readlines. http://docs.python.org/library/urllib2#urllib2.HTTPError For example, if you catch the error as e, then you can look at e.headers['www-authenticate'] to find the realm. Basic HTTP Authentication: http://docs.python.org/library/urllib2#examples You can also use an HTTPPasswordMgrWithDefaultRealm with a catch-all realm (realm=None): pass_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm() auth_handler = urllib2.HTTPBasicAuthHandler(pass_mgr) auth_handler.add_password( realm=None, uri='https://mahler:8092/site-updates.py', user='klem', passwd='kadidd!ehopper') opener = urllib2.build_opener(auth_handler) Optionally, install the opener: urllib2.install_opener(opener) Or just use opener.open(). ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

I have a question. In a assignment it asks for me to do the following below... if peek then print the Student object at the beginning of the list (using __str__) but don't remove it from the list; Could you explain what it means? This is what I have so far, elif ask == peek: print(First Name In List =, names[0]) How would you make it a string? I know have a example of it but I'm not sure how to apply it to my code...The example is below. def __str__(self): return self.sides + \t + self.value Also below is part of the assignment and my whole code is in the attachment. A main function which does the following: (1) create an empty list; (2) ask the user if he/she wants to perform a list operation. if yes: (a) prompt the user for the operation: test, peek, add, or remove; (b) perform the operation: (i) if test then print whether the list is empty or not; (ii) if peek then print the Student object at the beginning of the list (using __str__) but don't remove it from the list; (iii) if add, then prompt the user for student info, make a Student object containing that info, and add that Student object to the end of the list; (iv) if remove, then delete the Student object at the beginning of the list and print it using __str__; repeat step (2) until the user enters no; (3) neatly print the entire list from beginning to end.

It struck me that you're not assigning int(spag_ent.get()) to any variable:
spaghettiAmount = int(spag_ent.get())
Moreover, I'd try to create the program in such a way that it doesn't become a
headache to change the menu (for instance, to add a new pasta).
Perhaps by using a dctionary as a parameter: menu = {spaghetti: 4.50,
macaroni: 2.10, calzone: 6.00}
Your example reminds me of one chapter of Head First Design Patterns
(O'Reilly). Would be interesting to compare your approach with the one in the
book.

The __str__ special method of an object will be called when passed to
the built-in str() constructor. This method is required to return a
string.
For example, here's a class with an __str__ method that prints
calling __str__ to the screen in addition to returning the string
eggs. This demonstrates some of the ways __str__ is implicitly
called.
class Spam:
def __str__(self):
print(calling __str__)
return eggs
s = Spam()
str(s)
calling __str__
'eggs'
spam and {}.format(s)
calling __str__
'spam and eggs'
print(s)
calling __str__
eggs
Make sure __str__ returns a suitable string representation of the
student. The assignment should specify the string formatting of
Student objects.

[Tutor] How to send email from a gmail a/c using smtp when port 587(smtp) is blocked
Hi Python Tutor folks
I am stuck with an issue, so am coming to the Pythonistas who rescue me
everytime :)
I am trying to send out email programmatically, from a gmail a/c, using
smtplib, using the following chunk of code (b/w [ ] below)
[
import smtplib
from email.mime.text import MIMEText
#uname, pwd are username password of gmail a/c i am trying to send from
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls() # get response(220, '2.0.0 Ready to start TLS')
server.login(uname,pwd) # get response(235, '2.7.0 Accepted')
toaddrs = ['x...@gmail.com', 'y...@gmail.com' ] # list of To email addresses
msg = MIMEText('email body')
msg['Subject'] = 'email subject'
server.sendmail(fromaddr, toaddrs, msg.as_string())
]
The code above works perfectly fine on my local machine, but fails on the
production server at the university where i work( all ports other than port
80 are blocked) :(
So , when i try to run the 2 py statements (in bold below) on a python
prompt from the production server, which has port 587 blocked, i get the
following error
{
* import smtplib*
* server = smtplib.SMTP('smtp.gmail.com:587')*
Traceback (most recent call last):
File stdin, line 1, in module
File /usr/lib/python2.6/smtplib.py, line 239, in __init__
(code, msg) = self.connect(host, port)
File /usr/lib/python2.6/smtplib.py, line 295, in connect
self.sock = self._get_socket(host, port, self.timeout)
File /usr/lib/python2.6/smtplib.py, line 273, in _get_socket
return socket.create_connection((port, host), timeout)
File /usr/lib/python2.6/socket.py, line 514, in create_connection
raise error, msg
socket.error: [Errno 101] Network is unreachable
}
1. How can i overcome this ?
A friend suggested , that i could use something called smtp relay, which
would solve my problem, but would be time-consuming a pain to set up.
I did some cursory googling searching on stackoverflow but could not find
any good, well explained results.
I dont know anything about SMTP.
Anybody has any recommendations on a good explanation on smtp relay how
to set it up for sending email from a gmail a/c using a python script ?
2. Also, is there a more elegant/cleaner/graceful solution to my problem
than using an smtp relay ?
Any all explanations/links/code
snippets/thoughts/ideas/suggestions/feedback/comments/ of the Python tutor
community would be greatly appreciated.
Thanks a ton
cheers

We are a tiny startup trying to connect rural communities using voice ivr systems - http://gramvaani.org/ OK, well I'm sure you can see how an apparent newbie asking to get out of a university network without any explanation can be seem um, suspect, so I think Emile's response was reasonable. I must further note that I can't actually see how/where your request actually fits under the projects listed by that site. So, colour me still a bit sceptical, but I'll give you the benefit of the doubt. So then, given that you can only get out on port 80, your only real option the way I see it is to write a small web service, maybe a SOAP or preferably ReST service, to run on e.g. Google APP engine that will do the emailing for you.Of course, you'll have to consider whether to implement some security yourself if you use port 80 as the data going over the wire will be sent unencrypted. It may not be a problem but then again it may. Note, alternatively you can perhaps also use https (port 443), if that's also open as that will give you end-to-end encryption for free. (But I have no idea and suspect that this may also introduce a boatload of other complications...)

I think you might have been presuming Emile's intention too...
Blocking port 587 is a standard, prudent, and correct action for the
university (ANY network that allows guest access, actually) to take to help
prevent spam. The problem is that you (and I do, truly, presume that your
intentions are honorable) would not be the only person/system that could
use port 587 if it were unblocked. Sure, we trust YOU - but what about
everybody else?
So there are several ways to go about this:
- the standard way, which would be to use the university's SMTP server -
which can require a username/password before sending; not perfect but
better than nothing
- you can work with the university's network admin to grant you or your
app an exception to the firewall rule - IF their firewall, and their
policies, allow such an exception
- you could establish a VPN tunnel to some server outside of the
university's network and send from port 587 on THAT machine. Complicated,
weird, and not horribly secure. But doable.
Best,
ashish

Re: [Tutor] How to send email from a gmail a/c using smtp when port 587(smtp) is blocked
Walter, Marc, Thanks for your helpful suggestions super quick replies. As a noobie, i often run into brick walls, thinking something(problem i am stuck at) is not possible to do in python. I love struggling against that problem figuring a way out. I have posted to the tutor mailing list in the past the community here has always been amazingly welcoming super helpful, so as a n00b, i was just a little taken aback surprised at Emil's not particularly helpful , yet completely accurate response :) Marc, your 3rd point, you could establish a VPN tunnel to some server outside of the university's network and send from port 587 on THAT machine. Complicated, weird, and not horribly secure. But doable. Could you point me to a good link/resource on how to do this ? Walter, you suggested writing a web service running somewhere else (e.g. Google Apps, AWS, etc) which i could request from my python code, which in turn would do the emailing. Can you point me to any good links/example code which might explain writing a simple SOAP/ReST web service using port80(http) or preferably, 443(https). I know nothing about web services, but could this web service essentially be the python email code, i mentioned in my original post, if i run it on Google App Engine ?

We are a tiny startup trying to connect rural communities using voice ivr systems - http://gramvaani.org/ OK, well I'm sure you can see how an apparent newbie asking to get out of a university network without any explanation can be seem um, suspect, so I think Emile's response was reasonable. I must further note that I can't actually see how/where your request actually fits under the projects listed by that site. So, colour me still a bit sceptical, but I'll give you the benefit of the doubt. So then, given that you can only get out on port 80, your only real option the way I see it is to write a small web service, maybe a SOAP or preferably ReST service, to run on e.g. Google APP engine that will do the emailing for you.Of course, you'll have to consider whether to implement some security yourself if you use port 80 as the data going over the wire will be sent unencrypted. It may not be a problem but then again it may. Note, alternatively you can perhaps also use https (port 443), if that's also open as that will give you end-to-end encryption for free. (But I have no idea and suspect that this may also introduce a boatload of other complications...)

Re: [Tutor] Python in Vertica
A couple of points of order: please do a reply-all, or equivalent, so
your response goes to the forum, and not just to one person. or you can
add tutor@python.org to it, if that seem easier.
Also, please don't top-post on the forum, unless you're deleting all
context. And you usually shouldn't delete all of it, just the parts
that aren't relevant.

Since only part of the line was included, it gives a syntax error. Now
that I see the whole line, I realize what happened. See below.
This is the entire small test script:
#!/usr/bin/python
import pyodbc
import time
import os
import sys
cnstr = DSN=dwprod;PWD=S@1b@b@18;Charset=UTF-8
targetSchema = 'public'
cnxn = pyodbc.connect(cnstr, autocommit=False)
cursor = cnxn.cursor()
cursor.execute(SELECT COUNT(*) from cv_gls_wkly_misc)
result = cursor.fetchone()
number_of_rows = result[0]
print `number_of_rows`
Here you're using a deprecated form of syntax. The backquotes mean to
call repr() on the object inside. The repr() function tries to give you
enough characters that you could reproduce the object.
Just remove the backquotes, and you won't see the trailing L.
print number_of_rows
cursor.execute('SELECT * FROM cv_gls_wkly_misc where period_gen_key = 5185')
print cursor.fetchall()
cursor.close()
cnxn.close()
It is executed from the command line:
vertica1:dbadmin:/pro/COLEGIFT/source/fix/cece/sistest ./sisupd1.py
4L
[(5185L, 93L, Decimal(42.50), Decimal(50.36), Decimal(3406.35),
Decimal(0), Decimal(78.00), Decimal(0), Decimal(66.00), Decimal(0),
Decimal(12.73), Decimal(0), Decimal(0), Decimal(311.00))]
I do not know why it is printing a data type along with the value. I do not
know if this is a Python issue or a Vertica issue.

Complicated, weird, and not horribly secure. But doable. Could you point me to a good link/resource on how to do this ? Hmmm... having said that, I'm puzzling over the simplest way to actually do it. First idea (based on stuff I've set up in the past): - at your outside location, set up a VPN endpoint/router, with your SMTP server sitting behind it - on your computer inside the university's network, install a VPN client and establish the tunnel before launching your script I am very fond of pfSense http://www.pfsense.org as a router/firewall; it has OpenVPN http://openvpn.net/index.php/open-source.html support baked in, and if you install the OpenVPN Client Export Utility package (a single click, once pfSense is installed) it will export a ready-made configuration file for the remote machine. Two things: - as I said, this is a complicated and weird way to do this, although it's probably more secure than I thought when I first mentioned it. But it's probably NOT the best way to go about it. - somebody out there, with better Python chops than I, will no doubt point out a way to do the same thing all in Python. Even if this were the proper approach, I'm not guaranteeing it's the best way to implement it. If you do decide to go this way, you'll need a machine (it could even be a virtual machine, but I find it much simpler to use an old junker PC with two network cards) to run pfSense, and of course an SMTP server. I'd just like to add a quick endorsement for pfSense in general, by the way - it's free and open-source, but I have yet to find anything it doesn't do, and do well, compared to Cisco/Juniper/SonicWall/etc. Of course, the old junker PC you run it on needs to be in decent working condition - stable power supply (and power!), no flaky memory or unstable NICs - but it doesn't need to be very new or very powerful. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] Constructing a object
How do you construct a object using variables? For instance I have to construct a student object, by first prompting the user to enter variables for the Student class (their first and last names, credits and gpa) then construct a Student object using those variables. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

First you want to collect the variables from the user, like so: student_first_name = raw_input(Enter First Name: ) Enter First Name: David Then I would init the class with these variable, and return a tuple, or dict. If I'm getting the question you're asking correctly. Except I'd just use a function to call(instead of a class, but this might be the assignment given to you), and collect it there, then write the data to a db, or a custom db file. Or you could call the class without init, then go through the input in different functions by defining them as self.first_name = raw_input(Enter First Name: ), collect those into a return value, and pass them through another function/class that inserted the data into a db. -- Best Regards, David Hutto *CEO:* *http://www.hitwebdevelopment.com* ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] How to send email from a gmail a/c using smtp when port 587(smtp) is blocked
Why don't you ask the university to setup a password protection on port 587 to allow access to specific users, and then they can monitor the incoming/outgoing connections identified by the user name? As well as encryption known by the university to monitor activity on other levels. -- Best Regards, David Hutto *CEO:* *http://www.hitwebdevelopment.com* ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

For instance I have to construct a student object, by first prompting the user to enter variables for the Student class (their first and last names, credits and gpa) then construct a Student object using those variables. You need to write a function that gets user input and converts it where appropriate (e.g. int, float). def make_student_from_input(): # input and convert first_name = ... last_name = ... num_credits = ... gpa = ... return Student(first_name, last_name, num_credits, gpa) This assumes the Student initializer (__init__) is as follows: class Student(object): def __init__(self, first_name, last_name, num_credits, gpa): # ... The constructor supplies the 'self' argument in position 0. The rest, if supplied as positional arguments, need to be provided in exactly the same order as the argument list. The names do not matter. Whatever argument is in position 1 will be assigned to the local variable 'first_name'. Whatever argument is in position 4 will be assigned to the local variable 'gpa'. On the other hand, if you supply each argument name as a keyword, you're free to list them in any order. For example: first_name, last_name = 'John', 'Doe' num_credits, gpa = 60, 3.5 student = Student( gpa=gpa, num_credits=num_credits, last_name=last_name, first_name=first_name) ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
