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 this article, we will explore the functionality and usage of the index() function in Python. We will dive into the syntax, parameters, and various techniques to effectively utilize this function in your code. By understanding how to use the index() function, you will be equipped with a ...
Thereindex()function is another way to alter the DataFrame index. It conforms the data to match a given set of labels along a particular axis. This can be useful when you want to re-order the rows in a specific order, not just the default integer order. Let’s see it in action: df...
# v = "k1" in dic # print(v) # v = "v1" in dic.values() # print(v) #六、布尔值 # 0 1 # bool(...) # None "" () [] {} 0 ==> False ### # list # 类,列表 # li = [1, 12, 9, "age", ["石振文", ["19", 10], "庞麦郎"], "alex", True]...
Python中两种基本的数据结构是序列和映射,序列包含:可变的列表和不可变的元组;而当序列不够用时就出现了映射:字典。列表中的元素是可以变化的,元组里面的元素一旦初始化后就不可更改。列表和元组只是一类元数据的集合体,还不能满足通过名字引用值的数据,故字典就充当了这个功能角色。
Python的元组与列表类似,不同之处在于元组的元素不能修改,元组使用小括号,列表使用方括号,元组创建很简单,只需要在括号中添加元素,并使用逗号隔开即可。本文主要介绍Python 元组(tuple) index() 方法 原文地址: …
