title: getting the length of a set in python
in python, sets are unordered collections of unique elements. often, you might need to know the number of elements present in a set. this tutorial will guide you through the process of obtaining the length of a set in python.
using the len() function:
python provides a built-in function called len() to get the length of various data structures, including sets. the len() function returns the number of elements present in the set.
here's how you can use the len() function to get the length of a set:
output:
in this example, the set my_set contains five elements. we use the len() function to obtain the length of the set, which is then printed to the console.
example with an empty set:
what if the set is empty? let's see how the len() function behaves in such a scenario:
output:
even for an empty set, the len() function correctly returns 0, indicating that there are no elements in the set.
summary:
by following this tutorial, you've learned how to use the len() function to get the length of a set in python. this knowledge can be helpful in various programming tasks where you need to work with sets and determine their size.
