Python: Remove items from Python set

Python sets: Exercise-4 with Solution

Write a Python program to remove item(s) from a given set.

Sample Solution-1:

Python Code:

Remove single element from a given set:

num_set = set([0, 1, 3, 4, 5])
print("Original set:")
print(num_set)
num_set.pop()
print("\nAfter removing the first element from the said set:")
print(num_set)

Sample Output:

Original set:
{0, 1, 3, 4, 5}

After removing the first element from the said set:
{1, 3, 4, 5}

Sample Solution-2:

Python Code:

Remove all elements from a given set:

def remove_all_elements(num_set):
    while num_set:
        num_set.pop()
    return num_set
num_set = set([0, 1, 3, 4, 5])
print("Original set:")
print(num_set)
print("\nAfter removing all elements from the said set:")
print(remove_all_elements(num_set))

Sample Output:

Original set:
{0, 1, 3, 4, 5}

After removing all elements from the said set:
set()
