Use it., Experiment with it. Break it.
Thats the best way. Read the source code its all available in
Python or C.
Hey can you please tell me which source code youre referring too? The
initial files that come with Python? also the C code, where can i
locate this? is C something worth learning? why is Python code
available in C?
If you want to learn Python programming, read other Python programs.
You will find many Python programs, of greatly variable quality, here:
http://code.activestate.com/recipes/langs/python/
You might also like to read this book:

You can see the source code used by Python modules by searching for them on
your computer, then opening them in a text editor. But beware that you don't
accidentally modify them, because you may break your Python installation.
Another alternative is to read the source on-line. Many pages in the Python
docs link directly to the source code. E.g. this page:
http://docs.python.org/2/library/string.html
links directly to the source code:
http://hg.python.org/cpython/file/2.7/Lib/string.py
You can learn a lot from the source code of Python modules.
The source code of the Python interpreter, on the other hand, is much, much
more complicated. You will probably have a lot of trouble with it, since you
are unfamiliar with C, and unfamiliar with the internal C libraries used in the
interpreter. But if you are feeling masochistic and want to give it a go, you
will find the source code here:
http://hg.python.org/cpython
Click the "Browse" link to get to the latest version.
Many people will advise that learning C is a good idea. I understand their
arguments, but as an old curmudgeon I can say I don't like C and I think the
world would be much better without it :-)
The Python interpreter may be written in many different languages. C is only the most
common language. The "Big Four" Python interpreters are written in four
different languages:
CPython (what you probably think of when you say "Python"): C
Jython: Java
IronPython: Microsoft .Net CLR
PyPy: RPython ("Restricted Python")
but there are others:
CLPython: Common Lisp
Burp and Hope: Haskell
Nuitka: C++
Pynie: Parrot
Vyper: Ocaml
Skulpt: Javascript
although some of these may be experimental, obsolete or abandoned.
yes i will try not to reinvent the wheel, a lot of tutorials ive read
seem to always point this out. Just out of curiousity what is a bag,
stack or circular list? what is needed to create something like this?
i sort of heard about a stack its a C/C++ thing i think?
You can read about data structures like stack, bag (multiset) and circular list
here:
