script_18.py - Break Statement Example

Code

#!/usr/bin/env python3
"""Break statement example - find first multiple"""

target = int(input("Find first multiple of: "))
limit = int(input("Search up to: "))

for i in range(1, limit + 1):
    if i % target == 0:
        print(f"First multiple of {target} is: {i}")
        break
else:
    print(f"No multiple of {target} found up to {limit}")

Explanation

Line 4-5: Variable assignments - target is the number to find multiples of - limit is upper bound for search

Line 7: for i in range(1, limit + 1): - Searches from 1 to limit

Line 8: if i % target == 0: - Checks if i is divisible by target - % modulo returns 0 when evenly divisible

Line 10: break - Exits the for loop immediately - Jumps to code after the entire for/else block - Only executes when first multiple found - Stops searching once condition met

Line 11: else: - Special for/else construct in Python - else block attached to for loop (not common in other languages) - Executes if loop completes normally (without break) - Does NOT execute if break was called - If break happens, else is skipped - Used to detect "didn't find anything" scenario
