How to Use Break and Continue to Control the Flow of a Loop

Loops are a fundamental concept in Python, enabling you to automate repetitive tasks and handle data efficiently. With `for` and `while` loops, you can iterate over collections, repeat actions until conditions are met, and significantly reduce code complexity. Mastering loops allows you to write more efficient and elegant Python code, making your programming tasks easier and more powerful.

Loops in Python

For Loop

The for loop in Python is used to iterate over elements in a sequence, such as a list, and perform actions on each element.

Here’s a block of code to sum numbers in a list using a for loop:

numbers = [1, 2, 3, 4, 5]  # List of numbers to be summed
total_sum = 0              # Initialize the sum variable

for num in numbers:        # Loop through each number in the list
    total_sum += num       # Add the current number to the total sum

# After the loop, total_sum contains the sum of all numbers
