Python input does not compare properly [closed]

Answer 1

e is a string and you compare it to an int

do

def f():
    e=int(raw_input('enter number'))
    if e in range (12):
        print 'co'
    elif e in range (12,20):
        print 'co2'
    elif e in range (-10,0,1):
        print 'co3'

f()

instead
