Running the Hello World program

In the following steps, I will walk through how to run a program using the terminal.

1. In your Terminal program, go ahead and change the working directory to the directory containing your hello_world.py program:

$ cd <relative/path/to/directory>

2. Verify that you are in the correct directory by using the appropriate command for your operating system. Once you have verified that you are in the correct directory, run the program by entering either of the following, depending on your setup:

$ python hello_world.py 
$ python3 hello_world.py
