Python Set Operations – Python Tutorial

Python Set Operations : In this tutorial, we will learn about different python set operations, some of them are as follows :
- Set Contains
- Set Not Contains
- Set Length
- Set Deletion
- Set Min & Max
Set Contains
Operator in can be used to check, if a given element is present in the set or not. If a element is present in the set then return True otherwise return False.
# create set object and assign it to variable s
s = {1,2,3,4,5}
# example of contains
contains = 1 in s
print(contains)
contains = 6 in s
print(contains)
Set Not Contains
Operator not in can be used to check, if a given element is present in the set or not. If a element is present in the set then return False otherwise return True.
# create set object and assign it to variable s
s = {1,2,3,4,5}
# example of not contains
not_contain = 1 not in s
print(not_contain)
not_contain = 6 not in s
print(not_contain)
Set Length
Python’s len() function can be used to get the length of a set.
Syntax: len(< Set Object >)
For example:
# create set object and assign it to variable s
s = {1,2,3,4,5,5,6,6}
# call len() method to get length of the set s
length = len(s)
# print the value of variable length
print(length)
Set Deletion
We can use del statement to delete set object entirely. For example:
# create set object and assign it to variable s
s = {'Jan','Feb','Mar'}
# print set s
print(s)
# delete set s
del s
# print set s
print(s)
Set Min & Max
Python’s min() and max() function can be used to get minimum and maximum element in the set.
Syntax: min(< Set Object >)
max(< Set Object >)
For example:
# create set object and assign it to variable s
s = {1,2,3,4,5}
# call min() method to get minimum element in the set s
minimum = min(s)
# print the value of variable minimum
print(minimum)
# call max() method to get maximum element in the ser s
maximum = max(s)
# print the value of variable maximum
print(maximum)
