pop()是Python中的内置函数，可从列表或给定的索引值中删除并返回最后一个值。
用法:
list_name.pop(index)
参数：
index (optional) - The value at index is popped out and removed. If the index is not given, then the last element is popped out and removed.
返回值：
The last value or the given index value from the list
异常：
When index is out of range, it returns IndexError
代码1：
# Python3 program for pop() method
list1 = [ 1, 2, 3, 4, 5, 6 ]
# Pops and removes the last element from the list
print(list1.pop())
# Print list after removing last element
print("New List after pop:", list1, "\n")
list2 = [1, 2, 3, ('cat', 'bat'), 4]
# Pop last three element
print(list2.pop())
print(list2.pop())
print(list2.pop())
# Print list
print("New List after pop:", list2, "\n")输出：
6
New List after pop: [1, 2, 3, 4, 5]
4
('cat', 'bat')
3
New List after pop: [1, 2]
代码2：
# Python3 program showing pop() method
# and remaining list after each pop
list1 = [ 1, 2, 3, 4, 5, 6 ]
# Pops and removes the last
# element from the list
print(list1.pop(), list1)
# Pops and removes the 0th index
# element from the list
print(list1.pop(0), list1)输出：
6 [1, 2, 3, 4, 5] 1 [2, 3, 4, 5]
代码3： IndexError
# Python3 program for error in pop() method
list1 = [ 1, 2, 3, 4, 5, 6 ]
print(list1.pop(8))输出：
Traceback (most recent call last):
File "/home/1875538d94d5aecde6edea47b57a2212.py", line 5, in
print(list1.pop(8))
IndexError:pop index out of range
实际示例：
列表中的水果包含fruit_name和表示其水果的属性。另一个清单上的消费有两项果汁和食物。借助pop()和append()，我们可以做一些有趣的事情。
# Python3 program demonstrating
# practical use of list pop()
fruit = [['Orange','Fruit'],['Banana','Fruit'], ['Mango', 'Fruit']]
consume = ['Juice', 'Eat']
possible = []
# Iterating item in list fruit
for item in fruit:
# Inerating use in list consume
for use in consume:
item.append(use)
result.append(item[:])
item.pop(-1)
print(result)输出：
[['Orange', 'Fruit', 'Juice'], ['Orange', 'Fruit', 'Eat'], ['Banana', 'Fruit', 'Juice'], ['Banana', 'Fruit', 'Eat'], ['Mango', 'Fruit', 'Juice'], ['Mango', 'Fruit', 'Eat']]
