Fatal Python error: init_sys_streams: can't initialize sys standard streams Attribute

[FatalPythonError]

Find all the files in the filesystem named io.py or io.pyc or io.pyo, io.pyd etc

Searched entire PC there's only one io.py file. All other files just contain io.py in them so they show up in search results too.

Navigate in cmd to root folder of installation the type python.
This to make sure that Path don't mess up stuff.
Eg:

C:\Windows\System32>cd\

C:\>cd python37
C:\Python37>python
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:06:47) [MSC v.1914 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
C:\Python37>cd\

C:\>cd python36
# Just to make the error with 3.6
C:\Python36>python
