Python - Create a List of Floats Last Updated : 28 Nov, 2024 Comments Improve Suggest changes Like Article Like Report Creating a list of floats in Python can be done in several simple ways. The easiest way to create a list of floats is to define the numbers directly. Here’s how we can do it: Python a = [0.1, 2.3, 4.5, 6.7] print(a) Output[0.1, 2.3, 4.5, 6.7] Using List ComprehensionList comprehension is a shorter way to create lists. It’s very useful when we need to perform an operation while creating the list. Here’s how we can create a list of float numbers: Python a = [x * 0.5 for x in range(5)] print(a) Output[0.0, 0.5, 1.0, 1.5, 2.0] Using range() with map and lambdaIf you want to create a list of floats based on a mathematical operation, map() combined with lambda can be efficient. Python a = list(map(lambda x: x * 0.5, range(10))) print(a) Output[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5] Using numpy (for large lists or more complex operations)If you're dealing with a large number of floats or need specialized functionality like linspace, numpy is a highly optimized library for handling numerical operations. Python import numpy as np # List of 10 floats from 0.0 to 5.0 a = np.linspace(0.0, 5.0, num=10) print(a) Output[0. 0.55555556 1.11111111 1.66666667 2.22222222 2.77777778 3.33333333 3.88888889 4.44444444 5. ] Comment More infoAdvertise with us Next Article Python - Create a List of Floats P pragya22r4 Follow Improve Article Tags : Python Python Programs python-list Python list-programs Practice Tags : pythonpython-list Similar Reads Create a List of Strings in Python Creating a list of strings in Python is easy and helps in managing collections of text. For example, if we have names of people in a group, we can store them in a list. We can create a list of strings by using Square Brackets [] . We just need to type the strings inside the brackets and separate the 3 min read Python - Create List of Size n Creating a list of size n in Python can be done in several ways. The easiest and most efficient way to create a list of size n is by multiplying a list. This method works well if we want to fill the list with a default value, like 0 or None.Python# Size of the list n = 5 # Creating a list of size n 2 min read Average of Float Numbers - Python The task of calculating the average of float numbers in Python involves summing all the numbers in a given list and dividing the total by the number of elements in the list. For example, given a list of float numbers a = [6.1, 7.2, 3.3, 9.4, 10.6, 15.7], the goal is to compute the sum of the numbers 2 min read Python List Creation Programs Python provides multiple ways to create lists based on different requirements, such as generating lists of numbers, creating nested lists, forming lists of tuples or dictionaries, and more.This article covers various ways to create lists efficiently, including:Generating lists of numbers, strings, a 2 min read How to Add Floats to a List in Python Adding floats to a list in Python is simple and can be done in several ways. The easiest way to add a float to a list is by using the append() method. This method adds a single value to the end of the list.Pythona = [1.2, 3.4, 5.6] #Add a float value (7.8) to the end of the list a.append(7.8) print( 2 min read Like
