The PrettyTable Module in Python

The PrettyTable module for Python provides a simple and effective way to display tabular data, making data analysis more accessible and convenient. Let's explore how to install PrettyTable and look at how to use this module with practical examples.

Installing PrettyTable

1. Linux Mint

   To install PrettyTable on Linux Mint, you will need Python and the pip package manager. If they are not already installed, you can install them using the following commands:

   1sudo apt update
   2sudo apt install python3 python3-pip
   

   After installing Python and pip, install PrettyTable using pip:

   1pip3 install prettytable
   

2. Fedora

   On Fedora, the process is similar. Make sure you have Python and pip installed:

   1sudo dnf install python3 python3-pip
   

   Then install PrettyTable:

   1pip3 install prettytable
   

Examples of Using PrettyTable

1. Creating a Simple Table

   Let's start by creating a simple table with data:

    1from prettytable import PrettyTable
    2
    3table = PrettyTable()
    4table.field_names = ["Name", "City", "Age"]
    5
    6table.add_row(["Alexey", "Moscow", 30])
    7table.add_row(["Marina", "Saint Petersburg", 28])
    8table.add_row(["Igor", "Novosibirsk", 22])
    9
   10print(table)
   

   This code will create a table with three columns and three rows, where each row contains data about different people.

2. Changing the Appearance of the Table

   PrettyTable allows you to customize the appearance of tables, including text alignment:

   1table.align["Name"] = "l"  # Align name to the left
   2table.align["City"] = "l"  # Also align city to the left
   3table.align["Age"] = "r"  # Align age to the right
   4
   5print(table)
   

3. Adding Borders and Changing Style

   You can change the style of the borders and header of the table:

   1table.set_style(PrettyTable.DOUBLE_BORDER)
   2table.header_style = "title"
   3print(table)
