可以看到,name_age_dict是一个字典,包含两个键值对,键分别为name和age,值分别为对应的列数据。 5. 序列图 下面是一个使用mermaid语法表示的序列图,展示了将DataFrame两列转换为字典的过程: name_age_dictto_dictDataFramename_age_dictto_dictDataFrameto_dict(orient='list')返回字典 上述序列图描述了以下过程:...
Just make sure to call it in the right order. If you want to have a value of the first dict then you should callupdate()function on the second. # Get value of first dict states_2.update(states_1) print(states_2) 4.2 Use second dictionary value ...
字典是从键对象到值对象的映射。 Dictionaries are mappings from key objects to value objects. 字典由键:值对组成,其中键必须是不可变的,值可以是任何值。 Dictionaries consists of Key:Value pairs, where th...
