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)
