python loops

The program above

• prints all the odd numbers between 1 and 20

• prints all even numbers between 1 and 20

• print all the odd numbers between 1 and 21

• prints all the even numbers between 1 and 21

The equivalent of the above for loop using the while syntax would be

• 
• 
• 
• 

The above program prints

• Numbers 1 to 10 in reverse order

• Numbers 1 to 11 in reverse order

• Numbers 1 to 10

• Numbers 1 to 11

How many times will 1 be printed

• 3

• 4

• 5

• 6

for i in 100 :

print ( i )

• Syntax error

• prints numbers 0 to 100

• prints numbers 1 to 100

• prints numbers 0 to 99

• prints numbers 1 to 99

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

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
