It provides an environment for running text-based commands and typically offers features not available in graphical user interfaces (GUIs), such as piping and redirection. Shell is a command-line interface (CLI) for interacting with the operating system. Also, check this if you want to run scripts over ssh on a remote computer. It's the opposite of what we have in this post-hot to run python scripts from a terminal. ![]() If you're working with Python and shell scripts, you may also want to check the four different ways to run Python scripts inside a terminal. Linux Command Line and Shell Scripting Bible It helped me expand my understanding of shell scripts. I’ll’ be going through how to do both in this blog post! I recommend you check out Shell Scripting: How to Automate Command Line Tasks Using Bash Scripting and Shell Programming. The second option is more complicated to code, but it will allow for more customization in your script.

This is a powerful skill to have and there is so much more you can do with it. This article gives you a brief, simple introduction to running python scripts from the terminal (or command line). This is especially useful if you have a number of different scripts in the same directory that you will want to run. (base) c:\konrad\code\python\z_testing>python hello.pyīy using cd to change the terminal’s directory I no longer need to type the full path to the python script. (base) C:\Users\Konrad>cd c:/konrad/code/python/z_testing Second, use cd to change the terminal’s current directory. You can see that by specifying the full path to the python script that the terminal now knows where to find the file to run and I get the proper output. C:\Users\Konrad>python c:/konrad/code/python/z_testing/hello.py python: can't open file 'hello.py': No such file or directoryįirst, specify the full file path. If I just type python hello.py I get the following error. You’ll need to make sure that your terminal’s working directory is the directory that contains your python script, or give the full path to the script. All you need to do is type python followed by the script name. Once your Python script is created it’s super easy to run it from the terminal or command line. ![]() ![]() Hello.py print("Hello from my Python script") Run the Python Script from the Terminal This Python script (hello.py) will simply print out a statement that lets us know the code in the script has run, as shown below.

Make Sure Your Terminal or Command Prompt Can Run Python Once you are comfortable running Python scripts from the command line, continue improving your skills by learning how to pass arguments to your scripts. Once you’ve mastered that, you can get more complicated by passing in required arguments so that your scripts can stand on their own. This article will demonstrate how to get a simple Python script running on the command line in a matter of minutes.
