Python3 Web Framework
Hey all... I just started with Python, and I chose Python3 because it seemed a subtle choice as compared to doing Pthon 2.x now and then porting to Python3.x later... I plan to start with Web Development soon... I wanted to know what all web frameworks are available for Python3... I heard the Django is still not compatible with 3.x... Any idea guys? -- http://mail.python.org/mailman/listinfo/python-list
After C++, what with Python?
Hey all, I am a college student, and at college, we did most of the work in C/C++. I kind of stopped using C when I learned C++ (simply because C++ seemed a natural/elegant choice to me, and had backward compatibility with C). I've had a lot of experience with C++. Recently, I was on the path to learn a new programming language, and after suggestion of some of my friends and consulting the web, I chose to proceed with Python. I've finished with core Python and now I'm going through the various inbuilt packages that Python provides. I have an inquisitive mind, and while programming, I always want/tend to make something that is out of the box. It would be great if you people could guide me as to what to proceed with and how. -- http://mail.python.org/mailman/listinfo/python-list
Re: After C++, what with Python?
@nagle Means you are suggesting me not to proceed with Python because I've had experience with C++? -- http://mail.python.org/mailman/listinfo/python-list
Re: parsing packets
Are you sending binary data if so you can use the struct module to pack, unpack and interpret binary data http://docs.python.org/library/struct.html , You will have to design the header scheme yourself you can either embed length in the packets or try to use a carefully selected delimiter character .

Regular Expression for the special character "|" pipe
I would like to create a regular expression in which i can match the "|" special character too. e.g. start=|ID=ter54rt543d|SID=ter54rt543d|end=| I want to only |ID=ter54rt543d| from the above string but i am unable to write the pattern match containing "|" pipe too. By default python treat "|" as an OR operator. But in my case I want to use to as a part of search string. -- https://mail.python.org/mailman/listinfo/python-list

Thanks for the response.
I got the answer finally.
This is the regular expression to be
used:\\|ID=[a-z]*[0-9]*[a-z]*[0-9]*[a-z]*\\|
