What type of loop is used when you know exactly how many times you'll have to do something?

• While loop

• For loop

• If loop

• Do-while loop

What does the 'range' function determine in a for loop?

• All of the above

• Starting number

• Ending number

• increment/decrement

In a for loop, what is the variable 'i'?

• Boolean variable

• Float variable

• String variable

• Integer variable

What does the 'range' function do when given two numbers?

• Starts at the second number and decrements down by the first number

• Starts at the first number and goes up to the second number

• Starts at the second number and goes down to the first number

• Starts at the first number and increments up by the second number

What can the number in the 'range' function be?

• Only a constant value

• Only a variable

• Either a constant value or a variable

• Neither a constant value nor a variable

What are the two keywords that can be used to tweak the behavior of a loop in Python?

• stop, skip

• terminate, restart

• break, continue

• 
  end, start

What does a while loop allow you to do?

• Execute code once

• Check a condition repeatedly and execute code

• Terminate the program

• Skip the code execution

What happens when the condition of a while loop becomes False?

• The loop continues indefinitely

• 
  The loop switches to an if statement

• The loop stops executing

• The loop prints an error message

What is the potential risk of not allowing the condition to change during a while loop?

• 
  Memory leak

• Program crash

• Syntax error

• Infinite loop

Identify the purpose of -2 in the range.

for i in range(1,7,-2):

• start of loop

• increment

• end of loop

• decrement
