These "asserts" using only for self-checking and not necessary for auto-testing

if name == 'main': def almostequal(checked, correct, significantdigits): precision = 0.1 ** significant_digits return correct - precision < checked < correct + precision

print('Example:')
print(checkio(1, 2, 3))

assert almost_equal(checkio(1, 2, 3), 2, 3), "3-1=2"
assert almost_equal(checkio(5, -5), 10, 3), "5-(-5)=10"
