WebThe time complexity of a loop depends on the number of times the loop runs as a function of its input size. Example: Simple for loop for i in range (n): print (i) The time complexity of this loop is O (n), where n is the input size. This is because the loop runs exactly n times, printing the value of i each time. Example: Nested for loops WebOne of the main advantages of using sets in Python is that they are highly optimized for membership tests. For example, sets do membership tests a lot more efficiently than lists. In case you are from a computer science background, this is because the average case time complexity of membership tests in sets are O (1) vs O (n) for lists.
