How can I force division to be floating point? Division keeps rounding down to 0?
... to coerce one of the operands to a float. One robust solution is a / (b * 1.0). In a fresh Python shell:
>>> 1/(2 * 1.0)
0.5
Also robust is truediv from the operator module operator.truediv(a, b), but this is likely slower because it's a function call:
>>> from operator import tr...
What are “named tuples” in Python?
...a point as a tuple (x, y). This leads to code like the following:
pt1 = (1.0, 5.0)
pt2 = (2.5, 1.5)
from math import sqrt
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
Using a named tuple it becomes more readable:
from collections import namedtuple
Point = namedtuple('Point', 'x ...
