2. Remove Elements from Two Lists Using Python remove() First, we will iterate the first list using for loop and check if the elements present in the second list or not. If the element is present, we will remove that iterated element using the list.remove() method in both lists. In...
Another way we can remove elements from list/array in Python is by using the pop() method. It accepts the index of the element we want to remove. If we had the same array/list as before (with values from 10 to 100), we could write something like the following: index = 3 array.po...
