The Python set pop method is one of the set method, which is used to remove a random from a set. This is because, the Python set will not store the items using indexes. You can assign that removed item to a new variable for further reference.
The syntax behind this Python set pop method is
set.pop()
TIP: Please refer Python set article to understand everything about Sets.
Python set pop example
In this example, we declared a numeric set. Next, we used this set pop function to remove a random set item from the existing set.
# Python set pop
numeric_set = {150, 250, 350, 450, 550}
print('The Original Set : ', numeric_set )
numeric_set.pop()
print('The Set after pop: ', numeric_set)OUTPUT
This is same as the above example. However, this time we are assigning the removed set value to a new variable and printing the same.
numeric_set = {150, 250, 350, 450, 550}
print('The Original Set : ', numeric_set )
x = numeric_set.pop()
print('\npop Item : ', x)
print('The Set after pop: ', numeric_set)OUTPUT
Python pop example 2
In this example, we are using the set pop method to remove all the existing set items one after the other.
numeric_set = {15, 25, 35, 45, 55}
print('The Original Set : ', numeric_set )
x = numeric_set.pop()
print('\npop Item : ', x)
print('The Set after pop: ', numeric_set)
y = numeric_set.pop()
print('\npop Item : ', y)
print('The Set after pop: ', numeric_set)
z = numeric_set.pop()
print('\npop Item : ', z)
print('The Set after pop: ', numeric_set)
zz = numeric_set.pop()
print('\npop Item : ', zz)
print('The Set after pop: ', numeric_set)OUTPUT
This is same as the above example. However, this time, we are working with Python pop function on string set
fruits_set = {'Mango', 'Cherry', 'Apple', 'Kiwi'}
print('The Original Set : ', fruits_set)
x = fruits_set.pop()
print('pop Item : ', x)
print('The Set after pop: ', fruits_set)
y = fruits_set.pop()
print('\npop Item : ', y)
print('The Set after pop: ', fruits_set)OUTPUT
Here, we declared a mixed set. Next, we used the set pop method to remove a random item from a set.
mixed_set = {'Mango', 10, 'Cherry', 20, 'Apple', 30, 'Kiwi'}
print('The Original Set : ', mixed_set)
x = mixed_set.pop()
print('\npop Item : ', x)
print('The Set after pop: ', mixed_set)
y = mixed_set.pop()
print('\npop Item : ', y)
print('The Set after pop: ', mixed_set)OUTPUT
