Built-in Functions and Set Methods

Explore the use of built-in functions and methods to manipulate sets in Python. Understand how to check relationships such as subsets, supersets, and disjoint sets and apply these concepts practically.

We'll cover the following...

Using built-in functions on sets

Many built-in functions can be used with sets, as demonstrated below:

Python 3.8
s = {20, 10, 50, 40, 30}
print(len(s)) # return number of items in set s
print(max(s)) # return maximum element in set s
print(min(s)) # return minimum element in set s
print(sorted(s)) # return sorted list (not sorted set)
print(sum(s)) # return sum of all elements in set s
print(any(s)) # return True if any element of s is True
print(all(s)) # return True if all elements of s are True
