Install Python 3 on Windows 10
How to Install Python 3
Note: You can install it with Python 2.7
On the first screen, enable the “Add Python 3.x to PATH” option and then click “Install Now.”
Next, you have a decision to make. Clicking the “Disable path length limit” option removes the limitation on the MAX_PATH variable. This change won’t break anything, but will allow Python to use long path names. Since many Python programmers are working in Linux and other *nix systems where path name length isn’t an issue, turning this on in advance can help smooth over any path-related issues you might have while working in Windows.
If you’re only installing Python 3, you can use the same command line trick of typing python -v that we used above to check that it is installed correctly and the path variable is set.
