PIP problem

[Hubert]

I just started working with Python. Tried several ide's, and am not settling on Pyzo.

I have a serious problem with PIP. Whatever PIP command I use, I get an error like this:

Error:
>>> pip list
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

I have uninstalled Python and installed it again, but the error remains. On the web I found many people having similar problems, but I have not been able to find the solution.

Can anyone of you help?

Kind regards
