Removing an Element from a Set in Python

The discard method can also be used to remove an element from a set. The only difference from the remove method is that it returns the original set rather than an error when the element to be removed is missing.

Let us have a set:

pythonst = {'a', 'b', 'c'}

Let's remove the element 'b' from it:

pythonst.discard('b')
print(st) # {'a', 'c'}

Now let's remove the element 'd':

pythonst.discard('d')
print(st) # {'a', 'b', 'c'}

pythonst = {'x', 'y', 'z'}

pythonst = {1, 2, 3, 4, 5}

python{1, 3, 5}

pythonst = {'ab', 'cd', 'ef'}
st.discard('b')

print(st)
