The time complexity of the sum() function is linear in the number of elements in the iterable (list, tuple, set, etc.). Next, run a for loop till the entered number using the range() function. Functions make code more modular, allowing you to use the same code over and over again. Many programming languages have a special function that is automatically executed when an operating system starts to run a program. # this is a basic sum function def sum(a, b): return a + b result = sum(1, 2) # result = 3.
