You have a module called "hungry" and a function called "hungry" inside
that, so to reach the inner "hungry" you need to do this:

import hungry
hungry.hungry(96)


Which is no different from:

import math
math.cos(0.96)

Python will never try to guess which inner function you want when you
call a module directly, not even if the inner function has the same
name as the module. You must always explicitly tell it which inner
function you want.


An alternative is this:

from hungry import hungry  # like "from math import cos"
hungry(96)
