Linux ‘cal’ in Python With Example Code

If you’re working with dates in Python, you may find yourself needing to use the Linux cal command to display a calendar. Fortunately, Python makes it easy to execute shell commands and capture their output. In this tutorial, we’ll walk through how to use the cal command in Python.

First, we need to import the subprocess module, which allows us to execute shell commands:

import subprocess

Next, we can use the subprocess.check_output() function to execute the cal command and capture its output:

cal_output = subprocess.check_output(['cal'])

The check_output() function takes a list of arguments, where the first argument is the command to execute and any subsequent arguments are the command’s options and arguments. In this case, we’re only passing in the ‘cal’ command, which will display the current month’s calendar.

The output of the cal command is returned as a bytes object, so we need to decode it into a string before we can use it:

cal_output = cal_output.decode('utf-8')

Now we can print the calendar:


And that’s it! You can now use the cal command in your Python scripts to display calendars.
