Python – Creating and Using Lists
Python lists are used to store multiple items in a single variable.
Python – Accessing List Items
Python list items are indexed and can be accessed by referring to their index number.
Python – Changing List Items
Python list items are accessed and changed by referring to their index number.
Python – Adding List Items
Python list items are added to an existing list using the insert() method, append() method, or extend() method.
Python – Removing List Items
Python list items can be removed using the remove() method, pop() method, del keyword, or clear() method.
Python – Looping Through List Items
Looping through Python list items can be done by using a for loop, while loop, or list comprehension.
Python – Using List Comprehension
Python list comprehension offers a shorter syntax when you want to create a new list based on the values of an existing list.
Python – Sorting List Items
Python list items can be sorted using the sort() method in specified orders including reverse order.
Python – Copying Lists
Python lists can be copied to a new list using the copy() method, list() function, or slice operator.
Python – Joining Two or More Lists
There are several ways to join, or concatenate, two or more lists in Python.
Python – List append() Method
The Python list append() method appends an element to the end of the list.
Python – List count() Method
The Python list count() method returns the number of elements with the specified value.
Python – List extend() Method
The Python list extend() method adds the specified list elements (or any iterable) to the end of the current list.
Python – List index() Method
The Python list index() method returns the position at the first occurrence of a specified value of any type (string, number, list, etc.).
Python – List insert() Method
The Python list insert() method inserts the specified value at the specified position.
Python – List pop() Method
The Python list pop() method removes the element at a specified position.
Python – List remove() Method
The Python list remove() method removes the first occurrence of the element with the specified value.
Python – List reverse() Method
The Python list reverse() method reverses the sorting order of the elements.
