Python Tutorial #28 - List in Python Programming for Beginners In this video by Programming for beginners we will see List in Python Programming for Beginners, in Python tutorial for beginners series. Python programming language is very easy to learn for students and professionals. A list is a collection of similar or different types of data. For example, Suppose we need to record the age of 5 students. Instead of creating 5 separate variables, we can simply: Create a list: list = [17, 18, 15, 19, 14] Access Python List Elements: In Python, each item in a list is associated with a number. The number is known as a list index. We can access elements of an array using the index number (0, 1, 2 …). Negative Indexing in Python Python allows negative indexing for its sequences. The index of -1 refers to the last item, -2 to the second last item and so on. Slicing of a Python List In Python it is possible to access a section of items from the list using the slicing operator :, not just a single item. Add Elements to a Python List 1. Using append() 2. Using extend() Change List Items Python lists are mutable. Meaning lists are changeable. And, we can change items of a list by assigning new values using = operator. Remove an Item From a List 1. Using del() 2. Using remove() Iterating through a List We can use the for loop to iterate over the elements of a list. Python List Length In Python, we use the len() function to find the number of elements present in a list. Homework: Use list sort() function to sort elements in Python list. ========== Python Tutorial for Beginners Playlist:    • Python Tutorial   Java Tutorial for Beginners Playlist:    • Java Tutorial   All Java Programs Playlist:    • Java Programs   Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis.
