Method 1: Using the list() function

The list() function is the most straightforward and commonly used method to convert a set to a list in Python, as shown in the below program. It creates a new list containing all the elements from the set, in the same order as they appear in the set. 

# Sample set
my_set = {3, 1, 4, 2, 5}

# Convert set to list
my_list = list(my_set)

# Print the list
print(my_list)

Output:

[1, 2, 3, 4, 5]

In this example, the my_set set contains five elements in an unordered manner. We use the list() function to convert the set to a list called my_list. The resulting list contains all the elements from the set in ascending order, as per the default behavior of the list() function.

Method 2: Using the sorted() function

If you need to convert a set to a list with the elements sorted in a specific order, you can use the sorted() function along with the list() function. The sorted() function in Python returns a sorted list of elements from a collection, such as a set or a list, based on a specified sorting criteria. You can pass the set as an argument to the sorted() function and then convert the resulting sorted set to a list using the list() function.

# Sample set
my_set = {3, 1, 4, 2, 5}

# Convert set to list with sorted elements
my_list = list(sorted(my_set))

# Print the list
print(my_list)

Output:

[1, 2, 3, 4, 5]

In this example, we have a set called my_set containing five elements. We use the sorted() function along with the list() function to convert the set to a list called my_list. The sorted() function sorts the elements of the set in ascending order by default, and the resulting list contains the sorted elements of the set.

Method 3: Using list comprehension

To convert a set to a list in Python is by using list comprehension, which is a concise and efficient way to create lists in Python. List comprehension allows you to generate a list by specifying a concise expression and an iterable (such as a set) to loop over. 

# Sample set
my_set = {3, 1, 4, 2, 5}

# Convert set to list using list comprehension
my_list = [x for x in my_set]

# Print the list
print(my_list)

Output:

[1, 2, 3, 4, 5]

In this example, we use list comprehension to loop over the elements of the set my_set and create a list called my_list with the same elements. The resulting list contains all the elements from the set in the same order as they appear in the set.

Method 4: Using the extend() method

You can also use the extend() method of a list to append elements from a set to an existing list, effectively converting the set to a list. The extend() method takes an iterable (such as a set) as an argument and appends its elements to the end of the list.

# Sample set
my_set = {3, 1, 4, 2, 5}

# Create an empty list
my_list = []

# Convert set to list using extend() method
my_list.extend(my_set)

# Print the list
print(my_list)

Output:

[1, 2, 3, 4, 5]

In this example, we create an empty list called my_list and then use the extend() method to append the elements of the set my_set to the end of the list. The resulting list contains all the elements from the set in the same order as they appear in the set.
