In this tutorial, we explore various methods to replace values in a list in Python. We will cover several methods including:. Each method is explained with code examples and outputs. Data Structure.

Strings in Python: A string is a sequence of characters that can be a combination of letters, numbers, and special characters. It can be declared in python by using single quotes, double quotes, or even triple quotes. Lists in Python:Lists are one of the most powerful data structures in python. Lists are sequenced data types. In Python, an empty list is created using list function. Tuples in Python: A tuple is a sequence of immutable Python objects. Tuples are just like lists with the exception that tuples cannot be changed once declared.

In simple language, a list is a collection of things, enclosed in [ ] and separated by commas. The list is a sequence data type which is used to store the collection of data. Tuples and String are other types of sequence data types. Lists are the simplest containers that are an integral part of the Python language. Lists need not be homogeneous always which makes it the most powerful tool in Python. Lists are mutable, and hence, they can be altered even after their creation. Lists in Python can be created by just placing the sequence inside the square brackets[]. A list may contain duplicate values with their distinct positions and hence, multiple distinct or duplicate values can be passed as a sequence at the time of list creation. In order to access the list items refer to the index number. Use the index operator [ ] to access an item in a list. The index must be an integer.

Note: The position mentioned should be within the range of List, as in this case between 0 and 4, else wise would throw IndexError. We have mentioned some essential Python list functions along with their syntax and example:. What happens if a numeric value is not used as a parameter? Returns the index of the first occurrence. The start and end indexes are not necessary parameters. To Delete one or more elements, i. Note: The index must be in the range of the List, elsewise IndexErrors occur.

We are given two lists and our task is to show the implementation of list comprehension with those two lists. In this article, we will see how we can use list comprehension with two list in Python and perform various operations on them. Below are some of the ways by which we can use list comprehension with multiple lists in Python :. The result is a new list containing the sums. It filters out elements whose sum is not even.
