Initialize An Empty List With Certain Size In Python To create a list of size 10 (let's say), you can first create an empty array, like np.empty(10) and then convert it to list using arrayname.tolist(). alternately, you can chain them as well. This article explains how to initialize a list of any size (number of elements) with specific values in python. see the following article about initializing a numpy array (numpy.ndarray). an empty list is created as follows. you can get the number of elements in a list using the built in len() function.
How To Initialize An Empty List In Python In python, we often need to create a list with a specific size and initialize all elements with the same value. this is useful when we want to set up a list but don't yet have the exact values we need. there are several ways to do this. let’s start with the simplest way to create a list with repeated values using python. using multiplication. (tl;dr: the exact answer to your question is numpy.empty or numpy.empty like, but you likely don't care and can get away with using mylist = [none]*10000.) you can initialize your list to all the same element.
