Practical Uses of continue and break Statements

 

Example 5: Summing Non-Negative Numbers

Using continue to skip negative numbers and sum the non-negative ones.

numbers = [10, -5, 20, -10, 30]

total = 0

for num in numbers:

    if num < 0:

        continue  # Skip negative numbers

    total += num

print(f"Total sum of non-negative numbers is: {total}")

numbers = [10, 20, -5, 30, -10]

for num in numbers:

    if num < 0:

        print(f"First negative number is: {num}")

        break

Example 3: Skipping a Specific Number and Stopping at Another

    if i == 7:

        break  # Stop the loop when i is 7

    print(i)
