Feature Proposal: Addition of a switch Statement to Python

Proposal Description

This proposal suggests the addition of a switch statement to the Python programming language. A switch statement allows for cleaner and more concise handling of multiple branching conditions, enhancing readability and reducing the need for lengthy if-elif chains.

Motivation

The current lack of a switch statement in Python can lead to less readable and more verbose code when dealing with multiple cases. The proposed switch statement would address this by providing a more natural and compact way to handle branching logic.

Syntax and Usage

The proposed switch statement would have the following syntax:

switch expression:
    case value1:
        # code for value1
    case value2:
        # code for value2
    # ...
    default:
        # code for default case
# Example block of code of usage 
`def process_data(data, operation):
    switch operation:
        case 'add':
            result = perform_addition(data)
        case 'subtract':
            result = perform_subtraction(data)
        case 'multiply':
            result = perform_multiplication(data)
        default:
            result = handle_invalid_operation(data)

    return result
`
