In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. In this article, we will show you how to reverse the objects/elements in a list using python. The following are the 4 different methods to accomplish this task − Using built-in reverse() method Using the builtin reversed() method Using Slicing Using For Loop, pop() and append() Functions Assume we have taken a list containing some elements. We will return a new list after reversing all the items ... Read More

To remove items (elements) from a list in Python, use the list functions clear(), pop(), and remove(). You can also delete items with the del statement by specifying a position or range with an index or slice. In this article, we will show you how to remove an object/element from a list using Python. The following are the 4 different methods to accomplish this task − Using remove() method Using del keyword Using pop() method Using clear() method Assume we have taken a list containing some elements. We will return a resultant list after removing the given item ... Read More

In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. In this article, we will show you how to insert an item/object in a list at a given position using python. − Insert an item at a specific position in a list Insert an item at the first position in the list Insert an item at the last/end position in the list Assume we have taken a list containing some elements. We will insert an object in ... Read More

In this article, we will show you how to find the index of an object in a given input list using python. Below are the 3 different methods to accomplish this task − Using index() method Using For Loop Using List comprehension and enumerate() Function Assume we have taken a list containing some elements. We will return the index of a specified object in a given input list. Method 1: Using index() method The index() function in Python allows you to find the index position of an element or item within a string of characters or a list ... Read More

List is one of the most commonly used data structures provided by python. List is a data structure in python that is mutable and has an ordered sequence of elements. Following is a list of integer values − Example Following is a list of integer values. lis= [1, 2, 7, 5, 9, 1, 4, 8, 10, 1] print(lis) Output If you execute the above snippet, it produces the following output. [1, 2, 7, 5, 9, 1, 4, 8, 10, 1] In this article, we will discuss how to find the total count of occurrences of an object in ... Read More

Character classA "character class", or a "character set", is a set of characters put in square brackets. The regex engine matches only one out of several characters in the character class or character set. We place the characters we want to match between square brackets. If you want to match any vowel, we use the character set [aeiou].A character class or set matches only a single character. The order of the characters inside a character class or set does not matter. The results are identical.We use a hyphen inside a character class to specify a range of characters. [0-9] matches ... Read More

You can import any built-in module while writing Python script using TutorialsPoint's online IDE. For example you can import time, sys, os, re modules. However, the modules that are not bundled with the distribution - the one which needs to be installed using package managers like pip or conda - can not be imported.
