Use of if/else Statements in Python Functions

Functions can include conditional statements, loops, and variables. Previously, an if/else statement determined if a number was odd or even but required manual edits for different numbers. A better approach is to define a function that takes a number as input and applies the logic within, allowing reuse without redundancy.

# Define a function
def is_odd(n):
    if n % 2 == 0:
      return "even"
    else:
      return "odd"

# Testing function
print('2 is', is_odd(2))
print('3 is', is_odd(3))
copy

The function correctly identifies 2 as even and 3 as odd. This function can be invoked repeatedly with different numbers as needed.
