pytest: assert almost equal

Question

How to do assert almost equal with py.test for floats without resorting to something like:

assert x - 0.00001 <= y <= x + 0.00001
<         


        

Answer 1

I'd use nose.tools. It plays well with py.test runner and have other equally useful asserts - assert_dict_equal(), assert_list_equal(), etc.

from nose.tools import assert_almost_equals
assert_almost_equals(x, y, places=7) #default is 7
