Can we convert set object to list object?
We can convert a Set to List in Python using the built-in list() method. Lets take a look at some examples using this function. Show Methods to Convert a Set to List in PythonWell go over simple methods that will allow the conversion of a python set object to a list object quickly. 1. Using list() FunctionThe list() function takes an iterable as an argument and converts that into a List type object. This is a built-in method ready for you to use. my_list = list(my_iterable)
Since a set is also iterable, we can pass it into the list() method and get our corresponding list. my_set = set({1, 4, 3, 5})
my_list = list(my_set)
print(my_list)
The output, as expected, will be a list containing the above values. [1, 3, 4, 5]
Note that the order of the list can be random, and not necessarily sorted. For example, take the below snippet. s = set()
s.add("A")
s.add("B")
print(list(s))
Output in my case: ['B', 'A']
2. Using Manual IterationWe can also manually add the elements to the list since the set is iterable. This method does not have any real-world advantage over using the list() method apart from being written by you. s = set({1, 2, 3})
a = []
for i in s:
a.append(i)
print(a)
Again, the output is a list: [1, 2, 3]
Convert a frozenset to a listThe Python frozenset object is similar to a set but is immutable. Therefore, we cannot modify the elements of a frozenset. We can convert this type of set too, using list(). f_set = frozenset({1, 3, 2, 5})
a = list(f_set)
print(a)
Output [1, 2, 3, 5]
