Where all "the following" i can help you but you said which of the folllowing and ther no picture or anything?
If you save the input as num,
this will print the input 8 times.
num = input("Enter a number: ")
print(num * 8)
If you want to do actual math calculations,
then the input needs to be a number.
num = float(input("Enter a number: "))
print(num * 8)
This doesn't account for any errors in which the user doesn't input a number, but I don't think that's what you were looking for anyway :)
