python print dict分行显示 Python中字典的分行显示 简介 在Python中,字典(dictionary)是一种非常常用的数据结构,用于存储键值对。当字典中的键值对较多时,如果直接使用print函数打印字典,可能会导致输出结果过长,不易于阅读。因此,我们需要将字典的内容按行显示,以提高可读性。 本文将向刚入行的小白开发者介绍如何实现...
可变数据(3 个):List(列表)、Dictionary(字典)、Set(集合)。 可更改(mutable)与不可更改(immutable)对象 在python 中,strings, tuples, 和 numbers 是不可更改的对象,而 list,dict 等则是可以修改的对象。 不可变类型:变量赋值 a=5 后再赋值 a=10,这里实际是新生成一个 int 值对象 10,再让 a 指向它,...
