How to Format a Column List in Python for Enhanced Readability?

How to Create a Well-Formatted Column List in Python

When working with admin tools on the command line, creating a presentable column list is essential for readability. This article tackles this challenge, explaining how to turn raw data into a visually pleasing table.

Utilizing a format string in Python, we can define the minimum width of each column and align the text to the right. Here's how:

<code class="python">table_data = [
    ['a', 'b', 'c'],
    ['aaaaaaaaaa', 'b', 'c'], 
    ['a', 'bbbbbbbbbb', 'c']
]
for row in table_data:
    print("{: >20} {: >20} {: >20}".format(*row))</code>

This code will generate a table with the following format:

               a                    b                    c
      aaaaaaaaaa                    b                    c
               a           bbbbbbbbbb                    c

Each column displays a minimum of 20 characters, with data being aligned to the right. This approach ensures a clean and structured display of data, making it easy to compare rows and columns in the table.

By implementing this solution in Python, you can achieve the same formatting capabilities as Linux's 'column -t' command, allowing you to present tabular data in a visually appealing manner.
