If you wish to run Python on a Microsoft Windows system, you can use WinPython. The first window you will see when run run the downloaded installation file is one for the license agreement, which notes "WinPython components are distributed as they were received from their copyright holder, under their own copyright and/or license, and without any linking with each other." WinPython itself uses the MIT license.
Once you accede to the license, you will be prompted for a destination folder. By default that will be a WinPython directory created beneath the directory where you're running the downloaded file from, but you can change the location.
When the installation has been completed, a window will appear where you can click on a Finish button to exit from the installation program.
The following output from the dir command shows the files and directories installed for WinPython 32 126.96.36.199Zero.

You can get a Python command prompt, such as you would have with a
command-line interface (CLI) to Python on a
OS X system by
double-clicking on the
WinPython Command Prompt application in
the File Explorer.
You will then see a prompt like the one below where you can start
Python by typing
python and hitting Enter. You will
then see Python's
>>> prompt where you can enter
C:\Program Files (x86)\WinPython\scripts>python Python 3.5.4 (v3.5.4:3f56838, Aug 8 2017, 02:07:06) [MSC v.1900 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> 3 + 2 5 >>>
You can exit from Python by typing
exit(). If you want
to run a Python script, you can run them from that command prompt interface
python scriptname where scriptname is
the name of the script. E.g., I could use Notepad to create a simple
script by putting just
print ("Hello, world!") in a file
and then saving it as helloworld.py by selecting
"All Files" for the Save as type value rather than the default value of
"Text Documents (*.txt)". When I want to run the program I can use a command
like the one below:
C:\Program Files (x86)\WinPython\scripts>python c:\temp\helloworld.py Hello, world! C:\Program Files (x86)\WinPython\scripts>
You can obtain another command line interface for running scripts
by double-clicking on
WinPython Powershell Prompt, which
will run Python from a
Alternatively, you can run Python scripts using the
IDLEX (Python GUI) program you will see in the installation
If I had already written the "Hello, world!" script, I could run it by clicking on File then selecting Open and browsing to the location of the script. The script will open in another window where I can click on Run and then Run module to execute the script (or you can just hit the F5 key to run the script.
The output will appear in the first window.
