Python math.isclose() to check for “almost equal”

Had an issue with checking whether a sum of floats sums up to a number, remembering that python floats are ‘special’:

>>> 0.1 + 0.2

Stack overflow1 told me about math.isclose(), works as you’d expect:

assert math.isclose(sum(floats), needed_sum)

  1. python - pytest: assert almost equal - Stack Overflow ↩︎
