Once the installation is complete, Python will be ready to use.

Once the installation is complete, open a command prompt. For the command prompt, right-click on the Windows menu, select 'Run', enter 'cmd' as the name and click the OK button.

To start using Python, open the command prompt and type "python" followed by the Enter key.

If the Python version information is displayed, as shown in the screenshot below, you have succeeded. Once the version information is displayed, close this command prompto.

Create a directory called 'python' directly under the C drive. This is where you will store the Python program.

After creating the directory, create an empty text file called '' in it. Then open '' in Notepad or similar, type print('hello') and save it. This is a Python program to display 'hello' on the screen.

After saving the file, open a command prompt and run the following command.

python c:\python\

If you see hello after the command as in the screenshot below, you have succeeded.

The simplest way to run a Python program is to type 'python program file path' at the command prompt, as shown here.
