- Python list to set using set() constructor. This is the direct and most common way to convert a Python list to a set. The built-in set() constructor takes an iterable (like a list) and returns its set equivalent, automatically removing any duplicates.
- Python convert list into set using set comprehension. Set comprehension provides a concise way to create sets in Python, similar to how list comprehension works for lists.
- Use for loop to convert list into set in Python. This manual approach involves iterating over a Python list and adding each element to a set using a for loop.
- Python list to set using map() function. The map() function in Python applies a function to each item in the list. It’s ideal when we want to transform each list item before converting it to a Python set.

List in python is defined as the ordered collection values of different data typesinside a square bracket . From the above image, we can have an overview of the list. Here, 0,1 and 2 are the index. Alia, Meera, and Arya are the values or elements of the list having ‘string’ data type. But the list can beLi = [0, ‘Suman’, 0.24, True].The length of t...
Set in python is defined as the unordered collection of unique items having different data types inside a curly bracket {}. For example, Se = {1, ‘Mandeep’, True} or may be Se = {‘Sheetal’, ‘Karun’}.
You may be wondering if both list and set can hold items having different data types than what is the difference between them? Till now you have understood the concepts of list and set. But the question is why do we need this conversion from the list to set? The answer is that set does not allow duplicate elements. If we use a set then the elements...
we need to remove duplicate elements because there are many instances when we don’t need duplicate values. Well, let me explain this with the help of an example. In real life whenever a user makes an entry into the database, there are high chances that he might commit a mistake while entering data. Suppose a teacher is entering the marks of student...
You have understood why we need to convert List to Set. Now let’s explore how to convert the list to a set. There are many approaches to doing this.
Every algorithm and every code in this world has a certain space and time complexity. The time complexity of converting a list to a set is linear i.e., the number of elements present in the list. So, if the set has ‘n’ elements, the time complexity is O(n). The reason behind this is that the loop will iterate over each element present in the list t...
As we all know python is a very simple language to understand because of its simplicity. Due to this the conversion of the python list becomes simpler and easier to read. It’s even simple to understand at what cost we can convert through the time complexity. The time complexity is O(n) which is minimal.
List in python is ordered collection values.It can have any type of data.List is mutable.It can have duplicate elements.Let’s go through some questions to make our learning funand interactive. We can add a small exercise after every topic so that learners can perform them to gain their confidence. 1. Predict the output of the code? Ans: – 2. Complete the missing part of the code so that it displays the following as the correct output. {‘Abhishek’, ‘Ramesh’, ‘Mohan’,...
Learn how to convert a list to a set in python using three different methods: set(), custom function, and dict.fromkeys(). See the syntax, examples, and time complexity of each method.
Learn how to convert a list of elements into a set in Python using set() function or curly braces. See the difference between list and set, and how to handle duplicates.
- Using the set() Function. The simplest and most straightforward method to convert a list to a set in Python is by using the set() function. The set() function takes an iterable, such as a list, as an argument and returns a set containing all the unique elements from the iterable.
- Using a For Loop and the add() Method. Another method to convert a list to a set is by using a for loop to iterate over each element of the list and adding it to a set using the add() method.
- Using Set Comprehension. Set comprehension is a concise and elegant way to generate sets in Python. It allows you to create a set in a single line of code, using an in-place for loop to iterate over the elements of a list.
- Using the dict.fromkeys() Though not as commonly used as the previous methods, you can also convert a list to a set by first converting the list to a dictionary using the dict.fromkeys() method, and then extracting the keys of the dictionary as a set.
Feb 2, 2024 · The simplest way to convert a list to a set is by using Python’s built-in method, the set() method. Converting a List with duplicate values will be automatically removed by the set() method and will retain the same unique elements as the initial List. The set() method only accepts one parameter as an argument:
May 24, 2020 · Learn how to convert a list to a set in Python using the set(...) constructor and the list(set(...)) method. See examples, time complexity, and how to preserve order or remove duplicates.
Feb 20, 2024 · Learn how to remove duplicates from a list by converting it to a set using different methods in Python. See examples of set constructor, set comprehension, loop, filter function, and union function.
