Answer:

num = int(input("enter a number:"))

print(num * 8)

Explanation:

num is just a variable could be named anything you want.

if code was like this num = input("enter a number:")

and do a print(num * 8)

we get an error because whatever the user puts in input comes out a string.

we cast int() around our input() function to convert from string to integer.

therefore: num = int(input("enter a number:"))

will allow us to do  print(num * 8)
