Python Loops

In programming, what is iteration?

• The repetition of steps within a program

• The order in which instructions are carried out

• A decision point in a program

• Testing a program to make sure it works

Why is iteration important?

• It determines the order in which instructions are carried out
• It allows code to be simplified by removing duplicated steps
• It allows multiple paths through a program
• It ensures the code works correctly

Which two statements are used to implement iteration?

• IF and WHILE
• ELSE and WHILE
• FOR and WHILE
• IF and ELSE

FOR loops are

• loops which run an unknown number of times

• loops which run for a specific number of times

• the same as if statements

• not part of programming

Which type of loop iterates until instructed otherwise?

• FOR loop

• WHILE loop

WHILE loops are

• loops which run an unknown number of times

• loops which run for a specific number of times

• the same as if statements

• not part of programming

A condition is

• a statement that is either True or False

• a string

• an integer

• a list

The condition for a while loop to continue could include which of the following?

• While something equals something
• While something is greater than something
• While something is True
• All of these

Which kind of loop would be used?
