[issue38552] Colored Prompt broken in REPL in Windows in 3.8

William Minchin  added the comment:

I can't reproduce this today: Python 3.8.6 (or 3.9.5) with PowerShell 7.1.3 on 
Windows 10 with Windows Terminal. Maybe it got fixed by a bugfix release of 
Python 3.8?

I'll close it for now.

[issue38552] Colored Prompt broken in REPL in Windows in 3.8

[William Minchin]

New submission from William Minchin :

I have a Python startup file that colorizes my prompt. This worked on Python 
3.7, but breaks on Python 3.8. I'm on Windows using Powershell 6.2.3, but `cmd` 
does the same.

Maybe related, but the colorization also failed on Python 3.7 if a virtual 
environment was active.

I am using `colorama` to provide the ANSI color codes.

The startup files:

```
import sys
import colorama

colorama.init()

_GREEN = colorama.Fore.GREEN
_YELLOW = colorama.Fore.YELLOW
_RESET = colorama.Style.RESET_ALL

print("setting prompt, {}, {}, {}.".format(_GREEN, _YELLOW, _RESET))
sys.ps1 = "{}>>> {}".format(_GREEN, _RESET)
sys.ps2 = "{}... {}".format(_YELLOW, _RESET)
print()
```
