For example, use [None] * 5 to create a list [None, None, None, None, None] with five elements None. Python Server Side Programming Programming. Python list is sequences; Each list item is assigned to its position or index. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. Lists are used to store multiple items in a single variable. In some situation, you will face the problem that, in your list, for every items, there is a \n as the last character.
