[Adam Jensen]

#!/usr/bin/env python3.4
good = False
s = input('Enter a number: ')
a = s.split('.')
n = len(a)
if n <= 2:
    for y in a:
        if y.isdigit():
            good = True
        else:
            good = False
            exit
else:
    good = False
if good:
    num = float(s)
    print(num * 12)
else:
    print('neener neener')
