[whats_really_hot]

This is the second post of mine. First, I would like to thank all u that
responded to first post. Here I repeat some of the questions of my first
post, because they were not properly answered or cause I didn't get straight
answers.
 In the first post u answered me that in Unix based platforms "cat" command
starts the creation of a module. OK, now I go on with some more queries.

1. When we type "dir()" in the interactive command line prompt get among all
the others the module "__name__" which really tell us the name of the module
that we are . But now we are in the interactive command line prompt, which
is a module with the name "__main__". Now, my question is, why isn't
__name__ = __main__? (Why isn't __name__ substituted by __main__?

Sorry for repeating this question but I didn't really get a clear answer.

2. What is the difference between "!=" and "<>" (which really mean
"different")?

3. Are the built-in tools (such as "len", "sort" etc) maintained in a folder
into the Python directory, so as I can access and edit them?

4.   What is the difference between "%d" and "%i" (which really point
integer values)?

5. What does it mean that Python is a "high-level language" and other
languages, such as C, are low-level?



Sorry for the simplicity of some of the above questions, but are crucial for
me for the full understanding of Python.

Thanks again for ur attention and immediate responds.
