![]() ![]() Make sure you keep your Python scripts organized and don’t clutter your computer with them.Īlways save them to the same location so you can open and edit them easily. Tips for Successfully Running Python Scripts That’s it! You just ran your first Python script. You will see the output “Hello World!” printed to the next line in the console. To run the script we wrote at the beginning of this tutorial, run the following line in the terminal or command prompt: The interpreter will read the file line by line, translate the code into bytecode, and send the bytecode off to be run. This tells the Python interpreter to execute the given file. In the terminal or command prompt, append the name of the file you want to run after the python command. ![]() What we want to do, however, is run an existing Python script. You can start the Python interpreter inside the terminal or command prompt by simply typing “python.” This opens an interactive session into which you can directly type Python commands. It reads a command, evaluates the command, prints the command, and loops back to find the next command. The Python interpreter is the application responsible for running Python code and scripts. This opens a Command Prompt.įollow the same steps to open Power Shell, but replace “cmd” with “shell.” Into the toolbar that appears there, type “cmd” and hit Enter. To open the command line prompt on Windows, click on the Start Menu in the bottom left corner of the screen. Open Command Prompt or Power Shell(Windows) The easiest way to open a terminal on a Linux machine is to use the keyboard shortcut Ctrl + Alt + T. Type “terminal” into the search bar and hit Enter. The easiest way to open a terminal is to press command + spacebar. Open A Terminal, Command Prompt, or Power Shellĭepending on your machine (Mac, Linux, Windows), you will open up either a terminal, command prompt or Power Shell. Open your text editor and create a file with the following line of code in it: In this tutorial, we’ll write a basic Python script that prints out the string “Hello World!” You can write a Python script using an IDE (Interactive Development Environment) like VS Code or Pycharm-or you can open a basic text editor and create a simple text file. Append the file name after the python command to run the script. ![]() Type python to start the Python interpreter.Open a terminal, command prompt, or Power Shell.Module_n_method() How to Run a Python Script in 3 Easy Steps Then run the code by invoking a method inside the module_name file using dot syntax: Once they are, type the following command to import the script: It’s easiest if the two files are in the same folder. When a Python script is run inside another script, it is called a “module.” To run a Python module from inside another Python script or module, import the second module into the file that needs to run it and invoke the method you want to run. Instead of manually searching through files to find a particular line of text, you could run a script. Rather than spending many hours updating a spreadsheet, you could run a script to input all the information. With the prevalence and availability of open-source code on forums and sites like GitHub, anyone can download and run small pieces of code to improve their workflows.Īutomating basic tasks on your machine increases your productivity. These days, it’s not just software developers and engineers who need to know how to run a Python script. The #1 Reason You Need to Know How to Run a Python Script Generally, if you are automating a simple task on your machine, all the code you need to run will happen within a single script. Some Python scripts do just one simple thing, while others might do many things or even farm out tasks to separate scripts and modules. Generally, it’s best to keep your code as short as possible and break tasks into separate modules for readability. A script is generally intended to be used directly by a user, whereas a module is code that runs inside another file.Ī Python script can be as simple as one line or could take up hundreds of lines within a file. What is a Python Script?Ī Python script is code written to perform a specific task. In this article, we’ll learn how to run a simple Python script. Learning how to run a Python script is not the same as learning how to code in Python, although if you want to write Python scripts, you will need to learn some basic syntax. You can start learning Python by checking out an online Python course. Millions of developers worldwide use Python to create applications, websites, and machine-learning tools. If you are a developer, learning how to run a Python script will allow you to test your code before deployment. Scripts are pieces of code that can automate tasks and make your workflow easier. ![]()
