On the other hand, the lists in Python are a well-ordered group of items that can be accessed using an index value. Lists are also changeable, but you can add, alter, or remove the items from the list anytime you need. Come and let’s dive down to understand how to convert sets into a Python list.
Note: Spyder tool on Windows 10 has been used in this guide.
In this example, we discuss the method for converting a set into a Python list. We elaborate this method by using the list() function. To convert the set into the list, we use a Spyder compiler to create a new file and learn how the list() function works. Python provides many built-in functions, and the list() function is one of them which converts sets into a list.
First, you create the set by adding values to it. Use list() function for set conversion into a list. In this function, you pass the set in the list as a parameter. So, in this program, we fed “set(roll_no)” as a list parameter to change the set into a list and assign it to the variable “res”. Then, we utilize the print() function to print the altered list on the terminal screen:
To check the output of the set conversion using the list() function, save your code file with the “.py” extension and then press F5 to compile the code:
In our second example, we use the manual iteration approach for converting a set into a Python list. We elaborate this method by manually adding the elements in the Python list. This method is time-consuming, and it is not commonly used compared to the list() method. This method takes too much time to add items to the list manually. To further explain the method, we use the same code file and apply modifications to it.
First, we create the set by adding values to it. Then, we create a blank list to manually fill it by elements. Next, we use a for loop that traverses over the set and adds elements in the list using the append() function. After this, we utilize the print() function to print the list on the terminal screen.
my_=list = 
for I in set_rollno:
Again, save your code file extension. Then, hit F5 to run the code and check the output on the console screen:
In our third example, we use the frozenset approach for converting a set into a Python list. The frozenset object in Python is an unchallengeable unorganized group of data items. Therefore, you cannot change the items of the frozenset. To change it into a list, apply the list function as an argument to access the list elements.
First, we create the frozenset by adding values to it. Then, we utilize the list method and pass the set as an argument. After this, we utilize the print() function to print the list on the terminal screen:
a_list = list(set_rollno)
Once again, save and run the program file to view the frozenset output on the console screen.
This tutorial recommends some basic approaches to convert a set to a Python list, along with a brief comparison and explanation of the list and sets. We have briefed three unique examples to explain the process of converting Python sets into a list. You can utilize any method to get a basic understanding of this topic.
