Remove an element from a Python list Using pop() method
List =[1,2,3,4,5]# Removing element from the# Set using the pop() method
List.pop()print("
List after popping an element: ")print(List)# Removing element at a# specific location from the# Set using the pop() method
List.pop(1)print("
List after popping a specific element: ")print(List)
# create a list of prime numbers
prime_numbers =[2,3,5,7]# remove the element at index 2
removed_element = prime_numbers.pop(2)print('Removed Element:', removed_element)print('Updated List:', prime_numbers)# Output: # Removed Element: 5# Updated List: [2, 3, 7]
