I guess it's a common case to search an odd number with expression num%2 != 0. Wonder what stands behind it comparing to num%2 == 1, especially in terms of its implementation in python.
Comparison in python (!= vs ==)

I would argue that while the workings are probably the same (haven't done any tests, but I don't expect any speed differences), the former is imho slightly more descriptive. That one says, execute if
numis not divisible by 2. The latter one says, execute ifnumdivided by 2 gives a remainder of one. While it may be completely equivalent for integers in this case, when using divisors greater than 2, having a remainder of 1 does not cover all cases wherenumis not divisible byx. Note that there is a case where you definitely should use the latter: when interested only in odd numbers and your inputs may be floats. I would consider 1.1 to be not odd (though not even either), but it has a remainder unequal to 0 when divided by 2.
