# Quick examples of removing last element from list # Initialize the list of strings technology = ["Python", "Spark", "Hadoop", "Pandas"] # Example 1: Remove the last element from the list # Using pop() method last_element = technology.pop() # Example 2: Remove the last element fro...
list.insert(index,obj)---在索引量为index的位置插入对象obj。 list.pop(index=-1)---删除并返回指定位置的对象,默认是最后一个对象 list.remove(obj)---从列表中删除对象obj list.reverse()---对列表进行倒序 list.sort(func=None, key=None,reverse=False)---以指定的方式排序列表中的成员,如果func和k...
Thedelfunction in python is used to delete objects. And since in python everything is an object so we can delete any list or part of the list with the help ofdelkeyword. To delete the last element from the list we can just use the negative index,e.g-2and it will remove the last ...
Traceback (most recent call last): File "<pyshell#7>", line 1, in <module> list1.remove(6) ValueError: list.remove(x): x not in list 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 当要删除list1中值为6的元素时,因为list1中不包含改元素,因此程序会显示异常,该异常的信息...
6. Remove Multiple Elements from List by Index To remove the multiple elements/items from the python list by index, you can use any above-mentioned methods, however, I will use the del keyword to explain. In order to use this you need a list of element indexes you wanted to remove and...
list()与tuple()接受可迭代对象作为参数,并通过浅拷贝数据来创建一个新的列表或元组。如果不考虑range()函数,python中没有特定用于列表的内建函数。range()函数接受一个数值作为输入,输出一个符合标准的列表。列表类型内建函数列表:---list.append(obj)---向列表中添加一个对象objlist.count(obj)---返回一个对...

Lists cannot be accessed beyond the rightmost index boundary. Here is an example : >>> myList[5] Traceback (most recent call last): File "<stdin>", line 1, in <module> IndexError: list index out of range So we see that when we tried to access myList index 5, an error was thro...
Please note that list.pop() returns the remove element, but del statement does not return the removed element. It raises IndexError if list is empty as it is trying to access an index that is out of range. Using slicing We can also use slicing to remove the last element. We can get...
python list.remove(),del()和filter & lambda 面试题之中的一个。 下面代码能执行吗? l = [1,2,3,4,5] for i in range(0,len(l)): print i if l[i] % 2 == 0: del l[i] print l 结果: Traceback (most recent call last):...
