Recap
Looping statements are very useful and necessary for developing applications.
The for statement executes a simple or compound statement for a fixed number of times.
The range() function is an in-built function of Python.
The while statement executes a set of statements repeatedly, until the logical expression
evaluates to true.
The break keyword in Python is used for bringing the program control out of the loop.
When a continue statement is encountered inside a loop, control of the program jumps
to the beginning of the loop for next iteration, skipping the execution of rest of the
statements of the loop for the current iteration.
