Why is this division not performed correctly?

Question

I\'ve a strange issue in Python: the division is not performed correctly:

print pointB[1]
print pointA[1]
print pointB[0]
print pointA[0]
print  (pointB[1]-         


        

Answer 1

The above behavior is true for Python 2. The behavior of / was fixed in Python 3. In Python 2 you can use:

from __future__ import division

and then use / to get the result you desire.

>>> 5 / 2
2
>>> from __future__ import division
>>> 5 / 2
2.5

Since you are dividing two integers, you get the result as an integer.

Or, change one of the numbers to a float.

>>> 5.0 / 2
2.5
