How to Run Python Programs in Linux Command Line

Starting with Python on Linux? Here's how you can run Python programs in the Linux command line.
Warp Terminal

Running programs is the first step in learning Python. Sure, there are great IDEs to run Python but what if you want to use the terminal only like most pro users do?

Well, in this tutorial, I will walk you through two ways to run Python programs in the Linux command line:

Using the python3 command (easy and recommended for new users):


Running it as a script:


So let's start with the first one.

Using the python3 command (easy)

This is the easiest way to run Python programs in Linux. Why?

Well, all you have to do is follow the given command syntax:

python3 <>

For example, here's a simple Python program that takes input from the user and then prints a greeting message:

def greet():
    # Prompt the user for their name
    name = input("Enter your name: ")

    # Greet the user
    print(f"Hello, {name}! Welcome to the world of Python.")

# Call the greet function

I've saved this program as so if I want to run it, then I have to use the following command:

Run python programs in Linux using the python3 commmand

As you can see, it asked for the input first and then used the input name to greet the user.

Running Python program as a script

If are familiar with how you run bash scripts in Linux and you want to use a similar approach then this is how you do it.

Things to remember while following this approach:

  • The file will still have the .py extension not the .sh.
  • You have to use the chmod command to make it executable.
  • You're required to use #!/usr/bin/python3 as a shebang.

Let's understand this with a simple example.

I will be using the same greetings program as I used to explain the usage of the python3 command.

First, I will use the nano text to create an empty file as shown:


Now, I will write the following line of code:


def greet():
    # Prompt the user for their name
    name = input("Enter your name: ")

    # Greet the user
    print(f"Hello, {name}! Welcome to the world of Python.")

# Call the greet function

You will notice I have used the same code and the only difference is the shebang line used at the beginning of the line.

Once done, save changes and exit from the nano editor.

Next, make the file executable using the chmod command:

chmod +x

Finally, you can execute it the way you execute scripts in bash:

Run python programs as script in Linux command line

There you have it.
