We have worked with the *if/else* structure when we worked with `for` loops. We can do the same with the `while` loop.

An if/else structure in a `while` loop will be working when the `while` structure is equal to the *False* value.

numbers = [1, 2, 4, 5, 7]
i = 0

# Checking even and odd
while i < len(numbers):
  if numbers[i] % 2 == 0:
    print(numbers[i], 'is an even number')
    i += 1
  else:
    print(numbers[i], 'is an odd number')
    i += 1

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!
