For Loop:

A for loop in Python is used to iterate over a sequence (like a list, tuple, or range) and execute a block of code for each item in that sequence.

Example program:

While Loop:

Example Program:

Loop Control Statements:

The break statement is used to immediately exit a loop when a certain condition is met.

Example Program:

Output:

Continue:

Skips the rest of the code inside the current loop iteration and moves to the next iteration.
