list.pop python3 code example

Example 1: insert python3

a = [1,2,3,4,5]

#a.insert(index_to_insert_at, num_to_insert)
a.insert(0, -1)

# a is now: [-1,1,2,3,4,5]

Example 2: python pop

# Python list method pop() removes
# and returns last object or obj from the list.
# .pop() last element .pop(0) first element

my_list = [123, 'Add', 'Grepper', 'Answer'];
print "Pop default: ", my_list.pop()
> Pop default:  Answer
# List updated to [123, 'Add', 'Grepper']
print "Pop index: ", my_list.pop(1)
> Pop index: Add
# List updated to [123, 'Grepper']

Example 3: 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]

Example 4: python list pop

# removes last element of list unless parameter is given
l1 = [1,2,3,4,5]
print(l1.pop()) # returns [1, 2, 3, 4]
print(l1.pop(2)) # returns [1, 2, 4, 5] removes element at given index
