Describe how a tab(or 4 spaces) is used in nested loops

Tabs (or 4 spaces) are used to show which loop is inside the other. An additional tab or 4 spaces shows that the code is nested inside another inner loop

Nested Loop

When one loop is put inside another loop

Infinite Loops

While Loops that use a Boolean statement that can never become false

Write a loop that will give the following results: C. The program will count from 7 to 11 by twos 3 times

for i in range(3): for j in range(7,11,2): print(j) *variable names may be different

While Loop Example

password = None while password != "myPassword1234": password = input("enter the password: ") if password != "myPassword1234": print("Your password is incorrect.") print("Correct password. Welcome.")

Infinite Loop Examples

while True: while 4>3: while "hello" == "hello" while 5 <= 5:

Write a loop that will give the following results: D. The program will count to 5 over and over again, forever

while True: for i in range(1,6,1): print(i) *variable names may be different

Write a loop that will give the following results: B. The program will print: Good morning, Steve as long as the variable "name" is equal to "Steve"

while name == "Steve": print("Good morning, Steve")

Write a loop that will give the following results: A. The program will print: Go! Go! Go! as long as the variable "x" is more than 50
