set remove() method examples in Python

Below are the different types of examples of the remove() method.

Example 1:

s = {2,3,4,5}
s.remove(4)
print(s)

Run Code >>

Output :

{2, 3, 5}

Example 2:

s = {2,3,4,5}
s.remove(10)
print(s)

Run Code >>

Output :

Traceback (most recent call last):
 File "E:\Python files\kmtomile.py", line 30, in <module>
   s.remove(10)
KeyError: 10

Example 3:

s = {2,3,4,5}
s.remove("2")
print(s)

Run Code >>

Output :

Traceback (most recent call last):
   s.remove("2")
KeyError: '2'

As you can see, here you remove the element “2” of string type, but in the specified set there is a 2 of integer type. Therefore, you got an error.

Example 4:

s= set((1,2,3))
s.remove(2)
print(s)

Run Code >>

Output :

{1,3}
