Definition

A function in Python is a reusable block of code that performs a specific task. Functions can accept input arguments, process them, and return a result.

Examples

def greet(name):

    return f"Hello, {name}!"

# Calling the function

print(greet("Kaashiv")) 

Features

  • Functions can be called multiple times
  • Helps in breaking down complex problems
  • Can accept zero or more parameters and return values.

Advantages

  • Write code once and reuse it multiple times
  • Improves code readability by organizing code into logical blocks.
  • Easier to maintain and update code

Uses

  • Automates repetitive tasks by defining functions
  • Helps in structuring code into logical units
  • Allows for abstraction of complex operations, simplifying the main program flow.
