continue statements are used inside of while loops to jump back to the start of the loop and reevaluate the loop's condition. In for loop's it jumps to the next iteration of the loop.

Example

while True:
    print('Who are you?')
    name = input()
    if name != 'Joe':
        continue
    print('Hello, Joe. What is the password? (It is a fish.)')
    password = input()
    if password == 'swordfish':
        break
print('Access granted.')
