list methods python

Python provides some very useful list methods that we can use to perform list operation very easily. Python has a great built-in list type named "list". To list the methods for this class, one approach is to use the dir() function in Python. In this tutorial, we went through some common Python list methods like append, extend, insert, pop, remove, clear, index, count, copy, and reverse. This method corresponds to the tp_iter slot of the type structure for Python objects in the Python/C API. This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Important thing about a list is that items in a list need not be of the same type. List literals are written within square brackets [ ]. If there are no further items, raise the StopIteration exception. The dir() function will … Example #Append lst = ['Hello', 'Python'] print(lst) lst.append('Tutorialspoint') print(lst) We also saw several examples of how to apply these methods in various situations. Methods with Description; 1: list.append(obj) Appends object obj to list: 2: list.count(obj) Returns count of how many times obj occurs in list: 3: list.extend(seq) Appends the contents of seq to list: 4: list.index(obj) Returns the lowest index in list that obj appears: 5: list.insert(index, obj) Inserts object obj into list at offset index: 6: list.pop(obj=list[-1]) This method removes the first item from a list whose value is equal to the value we specify. Python list pop() Python list pop() method is used to remove the element at the given index from the list. In order to remove an item from a Python list, we can use the list.remove () method. The List method in python can be defined as a data type used for storing a single or group of elements/ variables, and these data can be an integer, a character or a float. Creating a list is as simple as putting different comma-separated values between square brackets. Below are the list of python built-in methods which we can use on list: append(x) Adds an element at the end of the list. By default the pop() function uses -1 index, which is the last element of the list, and if the given index is out of range then it throws IndexError: pop index out of range exception. The list method can be functioning with a number of operators like sort(), copy(), append(), clear(), reverse(), remove(), pop(), insert(), count(), extend() and index(). The list is a most versatile datatype available in Python which can be written as a list of comma-separated values (items) between square brackets. A few of the basic list operations used in Python programming are extend (), insert (), append (), remove (), pop (), Slice, Reverse (), min () & max (), concatenate (), count … index, which is optional.
