General module name clash problem?

[jipjip]

Hello all,
just new to python..

Suppose i have a directory only with an empty file "pickle.py" .
In this directory i start the python interpreter and say:

>>import pygame

What happens?
I get an error message:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/site-packages/pygame/__init__.py", line 147,
in <module>
try: import pygame.surfarra y
File "/usr/lib/python2.5/site-packages/Numeric/Numeric.py", line 536,
in <module>
class Unpickler(pickl e.Unpickler):
AttributeError: 'module' object has no attribute 'Unpickler'

Why?
Because pygame needs a module namend "pickle.py" !
The first location python searches is my directory, so
the library module "pickle.py" is overwritten with my "pickle.py" .

The cause of this error is not that i import 2 different modules with
the same name, it's only because there is a file in my directory with
the same name of a module somewhere in the imported module tree.

I mean, this is a general problem.
Must i look for every module that gets importet for not clashing
with my module files residing in the calling directory?

Is the python package system insufficient, is there something wrong with
my opinions or do i need a "gotcha"?

Thank's in advance,
jipjip

Yes.

The package system is not insufficient but could solve your problem
actually. Don't put all your modules simply in the same directory but in a
package so that your `whatever.pickl e` does not clash with the standard
`pickle` anymore.
