Python Error

[Mayukh Chakraborty]

 Hi Terry,
1. The command py doesn't work. It gives me the error below :
C:\Users\mchak>pyFatal Python error: init_sys_streams: can't initialize sys standard streamsPython runtime state: core initializedAttributeError: module 'io' has no attribute 'open'
Current thread 0x00008290 (most recent call first):<no Python frame>

2. If I use py -0, I get two installed versions. However, if I try to uninstall from Control Panel, I see only 3.9 version
C:\Users\mchak>py -0Installed Pythons found by py Launcher for Windows -3.9-64 * -3.8-64
3. I tried to uninstall v3.9 and reinstall but it didn't solve the issue.

It is true that io has no OpenWrapper class.  The question is What is 
trying to use that?  What installer are you using?  I would 
(re)download the one from python.org.
