Hello, I'm studying the Python language, and I needed to update the version I was using 3.4 to 3.6 or higher, but I noticed a constant error when I installed Python 3.5, 3.6 and 3.7, when the installation is finished and I run IDLE , prints the following error on the screen:

Best to reinstall using proven method.

If for windows:
Python install part1
Python install part2

for Linux:
Python install Linux
