Sort complex data structures in Python (similar to the structure data structure in C) and python Data Structure In Python, sorting mainly involves two functions: sorted and List member functions sort. Apart from calling methods, the most significant difference is that sorted creates a sorted list and returns it, sort modifies the order of the original list side b
