Let me remind you that the `pass` statement is a null statement. Nothing happens when the statement is executed.

counter = 0

while counter < 10:
  counter += 1
  pass

Also as a reminder, in Python, a loop can have the `else` block, which will be executed when the loop terminates normally.

counter = 0

while counter < 10:
  print(counter)
  counter += 1
else:
  print('Done!')

We start learning Python loops with the for loop. A for loop is used for iterating over a sequence. Let's go!

With the while loop, we can execute a set of statements as long as a condition is true. We are going to work with this loop and handle different problems!

A nested loop is a loop inside a loop. Sound difficult? Don't worry! We will handle this loop!
