If you want to work with Python and your OS is Windows, here are some stept on how to create your environment to get started:
I recommend to use Python 3.x becuase Python 2.7 will no longer be maintained since 2020. More details here: https://pythonclock.org/
Double click on
python-3.6.0.exe file and follow the next steps. I choosed a custom installation for this setup. Make sure you have selected the checkboxes for
Install launcher for all users and
Add Python 3.6 to PATH
For Optional Features, you may select them all
Advanced Options I selected all checkboxes except those with Download debug
On Setup was successful window, I click on
Disable path length limit
And then I close the window.
Now you have Python 3.6 installed and ready to work.
This installation process will install IDLE editor if you selected the checkbox
tcl/tk and IDLE in Options Features
