In this Python tutorial, you will learn how to use list.index() method to find the index of specified element in the list, when there is one occurrence, multiple occurrences, or no occurrence of the specified element in the list with example programs. Python List index() – Get index of...
my_tuple[2][0]=0# 修改my_tuple的元素列表的内容print(my_list)print(my_tuple) 输出结果: 可见my_list也被修改了 这是因为:python的赋值语句不会创建对象的副本,仅仅创建引用。这里的my_list和my_tuple嵌入的列表共同引用同一个内存对象。 改变my_tuple所引用的对象的值时,my_list的值也会被改变,反之亦...

In Python, lists are versatile data structures that allow you to store and manipulate a collection of items. Sorting a list is a common operation that arranges the elements in a specific order, such as ascending or descending. Sometimes, you may also need to know the original position or in...
In this example,my_listcontains three elements, so the highest valid positive index is 2 (my_list[2]). Attempting to accessmy_list[3]results in anIndexErrorbecause there is no fourth element in the list. The Python interpreter's response to such an error is to halt the execution of the...
In this example, we have a list of five elements. We use the index function to find the index of element 30. The index of 30 is 2, which is printed on the screen. Example 2 of index() Function in Python In this example, we will find the index of a specific element in a string...
