And that can be simplified:
buns = 20
package_size = 8
total_packages = (buns + package_size - 1) // package_size
#desired answer 3
Or, to take better advantage of the Python library:
import math
total_packages = math.ceil(buns/package_size)
This is exactly what the ceiling and floor mathematical concepts are
needed for.
Note, I'm using the fact that the OP is writing in Python 3. If not,
one should probably add
from __future__ import division
.
