Fatal Python error: init_sys_streams: can't initialize sys standard streams
AttributeError: module 'io' has no attribute 'OpenWrapper'

Current thread 0x000070ac (most recent call first):

So changed content of io.py in C:\Python37\Lib.

The default path is not good C:\Users\<your_user_name>\AppData\Local\Programs\Python\Python36-32
As AppData is hided for normal use,so have to un-hide and look for io.py.

Try follow Python 3.6/3.7 and pip installation under Windows
So there not using the default path,but place for simpler access eg c:\python37
Then try python from cmd again.
