The simplest data collection in Python is a list. In while loop way of iterating the list, we will follow a similar approach as we observed in our first way, i.e., for-loop method. You can use python set () function to convert list to set.It is simplest way to convert list to set. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. Sets are used to store multiple items in a single variable. If it’s not a requirement to preserve the original order, we can deduplicate a list using the built-in set data structure. In this article we will see how to convert a Python set to a Python dictionary. Let’s understand with the help of example. In this post, we will see how to convert set to list in Python.

Practice 100+ Java coding questions Learn about Garbage collection in java A indepth guide to Java 8 Stream API Sets are written with curly brackets. The principle outlined above generally applies: where a set is expected, methods will typically accept any iterable as an argument, but operators require actual sets as operands. This approach is a bit faster but suffers from readability. numbers = [1, 2, 2, 3, 3, 4, 5] unique_numbers = list(set(numbers)) print(unique_numbers) Although this code looks very different from the first example, the idea is the same. my_set = {'Geeks', 'for', 'geeks'} s = list(my_set) print(s) chevron_right filter_none Output: ['Geeks', 'for', 'geeks'] edit. How to Convert Pandas DataFrame into a List?
