Assert two variables are almost equal in python

Question

Here are two variables: earnings_forecast, actual_earning (numerical variables)

I want to assert if both these variables are equal with a diffe

Answer 1

For those who still use Python 2.x, you could also use numpy.isclose()

from numpy import isclose as isclose
a = 100.0
b = 100.01

print isclose(a,b, atol=0.02)  # True

From the documentation:

For finite values, isclose uses the following equation to test whether two floating point values are equivalent.

absolute(a - b) <= (atol + rtol * absolute(b))
