I guess you mean cmd window?
Save an run this.

print('hello world')
input('press <Enter> to exit')

I pretty much never run a Python script bye double-clicking on it.
Always for first open cmd or cmder as i use,then type python my_script.py.
Or editor VS Code from start,
sometime for fast testing PyScripter as this editor allow no saving i can just copy in code from eg this forum and push run button.

How are running the script.
Bye double-clicking on it,or do you use an other method?

It's normal that File Associations is set to your main version in Windows Path.
From cmd:

C:\Windows>cd ..

C:\>python -V
Python 3.7.1

C:\>pip -V
pip 18.1 from c:\python37\lib\site-packages\pip (python 3.7)

C:\>python -c "import sys; print(sys.executable)"
C:\python37\python.exe

So File Associations for .py files for me set to point to Python 3.7.
This can be changed to what you want as show in link over.
For basic setup of Python in Windows:
Python 3.6/3.7 and pip installation under Windows
