HOW PYTHON COMPARES FLOATS AND INTS

Summary from the TLDR Web Dev newsletter

Python's comparison of floating-point and integer numbers can lead to unexpected results due to the lack of implicit type promotion and the use of infinite precision integers. CPython, a reference implementation of Python, uses a complex algorithm to compare floats and ints, which involves comparing signs, magnitudes, exponents, and actual values. That's why it's recommended to use library functions for comparing floating-point values to avoid unexpected results.
