A Practical Guide to Python Loops: for, while, break, continue, and enumerate

Loops are control flow structures that repeatedly execute a block of code while a condition holds, reducing redundancy and handling data of any size. Python offers two main loop types: the for loop, used when iterating over a known sequence or range, and the while loop, used when repetitions depend on a condition that may change at runtime. Control keywords like break and continue modify loop behavior — break exits the loop entirely, while continue skips the current iteration and proceeds to the next. The built-in enumerate() function simplifies indexed iteration by automatically pairing each item with its position, eliminating the need for a manually tracked counter variable. Together, these tools allow developers to write cleaner, more maintainable code by replacing repetitive manual logic with structured, readable loops.
