I have had similar problems. In my case, an active "PYTHONPATH" envvar was responsible -- "unset"ting this envar has resolved the problem for me. -- https://mail.python.org/mailman/listinfo/python-list
Re: Weird side effect of default parameter
This is a well known feature of Python. It's a very common "gotcha" to new Python programmers. Google "Mutable default parameters in Python" for long list of explanations and fixes. In short, don't use a mutable object as a default parameter. Gary Herron On 05/03/2018 12:47 PM, python-list@python.org wrote: Hello, I don't understand the behavior of the code below.

Weird side effect of default parameter
Hello, I don't understand the behavior of the code below. Why does the dict property "a" of both objects contain the same keys? This is only if "a=dict" is in the initializer.

Problems with pip (Windows 10)
Dear All,
Within the past week I have run into a problem with pip on my work machine

C:\>c:\Python36\Scripts\pip --version
pip 10.0.1 from c:\python36\lib\site-packages\pip-10.0.1-py3.6.egg\pip (python
3.6)
The only thing I have changed is I upgraded to Windows 10 version 1803.
pip had been working before that point, but my place of work might have changed
things as well from a network perspective.
Has anyone else seen something like this?
Sincerely,
Duane

Check to see if you have a tab after the colon in the last line. You
must use colons or spaces, but not both
/tabs/ or spaces.
