The operator module in Python provides a set of efficient functions corresponding to the intrinsic operators of Python. These functions are useful for simplifying and improving the readability of your code, especially when working with higher-order functions such as map(), filter(), and reduce(). Below is a list of some commonly used functions in the operator module, along with their descriptions and links to detailed guides for each function.
