The next line does exactly that, runs the echo command in our shell through Python. The first thing we do in our Python file is import the os module, which contains the system function that can execute shell commands. Os.system( "echo Hello from the other side!") Let's start by creating a new Python file called echo_adelle.py and enter the following: import os Python allows us to immediately execute a shell command that's stored in a string using the os.system() function. In this article, we will look at the various ways to execute shell commands in Python, and the ideal situation to use each method. Learning how to run shell commands in Python opens the door for us to automate computer tasks in a structured and scalable way. Python provides methods to run shell commands, giving us the same functionality of those shells scripts, with additional support from Python's ecosystem. However, as those tasks become more complex, shell scripts may become harder to maintain.įortunately, we can use Python instead of shell scripts for automation. It is common for developers and system administrators to automate routine tasks like health checks and file backups with shell scripts. Repetitive tasks are ripe for automation.
