how to prevent python import from looking into the current directory

[TP]

Hi everybody,

I would like to prevent the loading of modules in the current directory.
For example, if I have a personal module in the current directory
named "os", when I do "import os", I would like Python to import os
standard module, not my personal module of the current directory.
Is this possible?

Thanks
