This gives me a correct float answer (that being 16.6666666667) when i print:

float_cucumbers_per_person = float(cucumbers)/num_people

This also gives me the correct float answer:

float_cucumbers_per_person = cucumbers/float(num_people)

Why does putting both variables in the float function like this give an incorrect float answer (16.0)? :

float_cucumbers_per_person = float(cucumbers/num_people)

What exactly is happening so i can understand it better?


if the division involves two integers, python will floor (round down) the result. Casting to float after the rounding down will not give the desired output (giving rounding down has already occurred), which is why you cast one of the two numbers to float, so the division involves a float and the rounding down doesn’t occur


In python 3 there is only one type of division. Every time it gives float value.


Please be careful with your phrasing. “normal” division (/) will always give a float value, but python3 also has floor division (//) which will give an integer. So there are multiple types of division.
