While the + operator only works with two lists, this unpacking technique can be used for other iterables (e.g. tuples or sets), too. c=[*a,*b]# [1, 2, 3, 4] a=[1,2]b=(3,4)# c = a + b# TypeError: can only concatenate list (not "tuple") to listc=[*a,*b]# [...
In this tutorial, I will explain how toadd two numbers in Pythonwith detailed examples. As a developer, I once faced a scenario where I needed to quickly calculate the total sales from two different states, California and Texas, for a financial report. This tutorial will help you understand ...
extend(iterable) Adds a list, array, or other iterable to the end of array. insert(i, x) Inserts an element before the given index of the array. The following example demonstrates how to create a new array object by joining two arrays: import array # create array objects, of type integ...
In the above code snippet, we use nested for loops. The first loop picks each element in the main list and checks if it is a list type. If the sub-element is a list, it initiates anotherforloop to iterate this sub-list and add its values to the new list. Otherwise, it appends th...
