在上面的示例中，我们首先创建了一个包含5个元素的列表my_list。然后，我们使用pop(2)移除了索引为2的元素（即数字3），并将移除的元素赋值给变量removed_element。接着，我们打印出移除的元素和更新后的列表。最后，我们调用pop()函数（未指定索引）来移除列表中的最后一个元素，并同样打印出移除的元素和更新后的...
To remove a single element at random index from a list if the order of the rest of list elements doesn't matter: import random L = [1,2,3,4,5,6] i = random.randrange(len(L)) # get random index L[i], L[-1] = L[-1], L[i] # swap with the last element x...
Pythonmy_list = []try:popped_element = my_list.pop()except IndexError:print("Cannot pop from an empty list.")空列表：如果你尝试对一个空列表使用pop()方法，同样会引发IndexError异常。在使用pop()之前，检查列表是否为空是一个好习惯。五、总结 Python的pop()方法是一个功能强大且灵活的工具，它可...
