Tkinter module not found

[Shuaib]

Hey,

Even though I freshly installed Tcl and Tk, python still seem to have
problems accessing Tkinter module. Here is what says when I do "import
Tkinter"

==
Traceback (most recent call last):
  File "", line 1, in ?
ImportError: No module named Tkinter
==

Any ideas how to fix this problem? (Gentoo distribution)

Thanks.

Re: Tkinter module not found

[Shuaib]

Hey again,

I am using the latest python available on my system (2.4). So I don't
think that's the problem.

Any more ideas? Do I need to install Tkinter as a seperate
module/package? As I said, I've already installed Tcl/Tk, though.

Thanks for your time.

Re: Tkinter module not found

[Shuaib]

Well, I finally solved my problem. I just had to reinstall python with
the USE flags of tcl and tk.

#USE="tcl tk" emerge python

And now I can use Tkinter

Thanks guys!

How do I catch ExpatError exception?

[Shuaib]

Hey!

I am getting this exception.

xml.parsers.expat.ExpatError

But I am not able to catch it with "except
xml.parsers.expat.ExpatError:" It says "NameError: global name 'xml' is
not defined".

I am also not able to catch it with "except ExpatError:" Gives
"NameError: global name 'xml' is not defined"

How do I catch it? (I am parsing an xml file)

Also, how do I get the line number where an exception was thrown?

Thanks.

How do I get the helpful text that is thrown with the exception? Like
if the exception is " IOError: [Errno 2] No such file or directory:
'out.xml' "

How do I get the the text after IOError: ?

Thanks again.

Embedding python: GCC gives errors of "undefined reference" to Py_* functions.

[Shuaib]

Hey!

I am trying to embedd python into a C programe of mine. But when I try
to compile the C code, gcc gives errors like "undefined reference to
`Py_Finalize'" and the same kind for all the other functions. I have
incuded "Python.h".

Any idea what might be wrong?

Thanks.

Re: Embedding python: GCC gives errors of "undefined reference" to Py_* functions.

[Shuaib]

OK, I am not ashamed to admit that I am ashamed as I didn't search the
group for my problem before posting it yet again. The solution was
right there.

I have link in my libpython2.4.so while compiling.

$gcc -I/usr/include/python2.4/ -lpython2.4  -o foo foo.c

Embedding python: Segmentation Fault

[Shuaib]

Hi!

I am trying to embed python into a C programe of mine. When the
execution reaches the following line

pModule = PyImport_Import(pName);

It causes a Segmentation Fault Error. pModule is of type PyObject *, so
is pName.

What could be the possible reasons for the error?

Thanks for your time.
