Master Python Loops: From Basics to Control Statements

1. Origin of Loop Statements

When we need to execute a statement or a block of statements multiple times, writing them repeatedly is cumbersome and hard to maintain; loop statements were created to solve this problem.

2. Introduction to Python Loop Statements

Python provides for loops and while loops (Python does not have a do...while loop).

Loop Types

while loop : Executes the loop body while the given condition is true; exits when the condition becomes false.

for loop : Repeats execution of a statement or block for each item in a sequence.

nested loops : You can nest a for loop inside a while loop.

3. Loop Control Statements

Loop control statements can alter the execution order of loops. Python supports the following control statements:

break : Terminates the loop immediately and exits the loop block.

continue : Skips the rest of the current iteration and proceeds to the next iteration.

pass : A null statement that does nothing, used to keep the program structure syntactically correct.
