inspect is a module, inspect is the name. It is not a module for
editing Python code per se, but it will help with the other part.

I don't think the OP wants to edit python code *objects*, rather he
wants to edit python *source* code programmatically. Inspect is not
the tool for this.

I didn't tell him to use inspect to edit python code, I said it was
useful for the other part. The other part, as he mentioned on his
email is: "find specific
function definition, add another function call inside, find existing
call".

Yes, the OP was a little ambiguous. So I ought to mention [sigh, these
name] bicycle repair man

http://bicyclerepair.source...

It provides refactoring functionality for Python, so may have some bits
in it that will help (though I don't know how up to date it is).

Sorry but I said "in *.py file", meaning that file isn't executed to
edit objects in memory. It's instead saved in modified form, possibly to
be edited by user. Guess it's a common task for visual GUI editors and
any visual programming tools.

By visual GUI editors I will assume GUI designer tools. These tend to
not generate direct python code, glade-2 used to but glade-3 doesn't
anymore. Other tools like XRCed generates xrc, wxGlade has an option
to generate .xrc too, Qt Designer generates .ui and .qrc, Glade-3
generates .glade file, Gazpacho generates .glade, or a gazpacho format
or gtkbuilder format. In all these, it is recommended to use something
to work with the generated code, like libglade, wx.xrc and PyQt has
tools to convert .ui and .qrc to python modules but they don't affect
your custom code (it is also possible to load .ui using uic module).

With this we come back to my first email, where I told you it is not
recommended to generate direct python code, especially if you are
doing the kind of things you just mentioned. If you still want to
generate python code, from some other source, inspect can be helpful.

Thank you for detailed reply... but I still want to generate python
code. By the way, Python Package Index references code generators able
to generate Python code
(http://pypi.python.org/pypi?:action=browse&show=all...), which I'll
inspect later (especially their ability to *edit* code). Inspect might
be useful too.

Depending on what you want to generate, it may be good to generate
python code I won't try to change your mind on this. One of those code
generators there is mine, but it doesn't have an option to edit the
code neither it is in active development at all (got bored), and it
generates direct python code and other language to complement the
generated python code. But if I was going to add a possible code
editing/updating I would probably use inspect for the reasons
mentioned before.

My only intention with this email was to tell that it is pretty hard
to know what you are thinking, so it gets hard to point tools to use.
If you advance in your code generation tool, you may have a better
idea of what you want then you will get better answers too.
