For short commands, we do not need to write scripts. We use the command line:

In the search window of Windows, write:

cmd

Then press Enter to open the command prompt.

To open Python, inside the command prompt, write:

python
print("Hello World!")
### Hello World!

To close the Python, use:

exit()

To write a simple python file:

Open Notepad, inside Notepad, write: print("Hello, World!"), then save it as helloworld.py.

To run a Python file on the command line: Change the directory to the folder (e.g., Python38) that includes the file, then use the command:

cd C:\Python38
python helloworld.py

Output:

Hello, World!
