Python – Find Length of a Set

To find the length of a Set in Python, you can call Python built-in function len() and pass the set as argument to the function. len() function returns an integer representing the number of elements in the Set.


In the following program, we initialize a Python Set aSet with some integers and find the length of this Set using len() function.


# initialize set
aSet = {'apple', 'cherry', 'banana'}

# find set length
n = len(aSet)

# print the length
print(f'Length of the set is : {n}')
Try Online


Length of the set is : 3



In this Python Tutorial, we learned how to find the length of a given Set using len() function with the help of example Python programs.
