how to pop things out of list python

>>> l = ['a', 'b', 'c', 'd']
>>> l.pop(0)
'a'
>>> l
['b', 'c', 'd']

python list pop

my_list = [-15, 0, 67,45]
print(my_list) # [-15, 0, 67,45]
my_list.pop(3) # 45
print(my_list) # [-15, 0, 67]
#A negative index is an index that is numbered from the back of a list, instead of from the front.For example, the index -1 refers to the last item in a list, while the index -2 refers to the second-last item in a list.The pop() method can be used to delete an item in a list using a negative index.


my_list.pop(-1) # 0
print(my_list) # [-15,0]

python list pop

# Python pop list

some_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] # normal python list
print(some_list) # prints [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

some_list.pop() # pop() is used to pop out one index from a list (default index in pop is -1)
print(some_list) # prints [1, 2, 3, 4, 5, 6, 7, 8, 9]

=====================================================
# Output:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[1, 2, 3, 4, 5, 6, 7, 8, 9]

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)

python list pop

# 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]
