Loops – for and while

Loops are fundamental constructs in programming that allow for the execution of a block of code multiple times based on certain conditions. This chapter covers two primary types of loops in Python: 'for' loops, which iterate over sequences, and 'while' loops, which continue until a specified condition becomes false. Additionally, control statements like break, continue, and pass are discussed to manage loop behavior more effectively.
