Python input not working

[Mar10]

Hello, I just installed python 3.9 and now its not working correctly.

Example:
I typed this simple script.

name = input ("Enter Your Name Pleas:")

print ("Hello" + name)

FIRST PROBLEM:
When I run this script the prompter DO NOT show Enter Your Name Pleas before the prompter/

SECOND PROBLEM:

If I enter any name an error is shown name is not defined

EVEN WORSE

Sometimes it does not print anything the prompt is just there blinking.

I hope you can help me out , I try searching on the web but not luck.
