pandas两列转换成字典的健和值

两列转换成字典的key和value

df:

name	age
Mary	26
Sellina	28
Zaca	27

想将name这列变成字典的健，年龄对应成字典的值，健值对应如下：
{‘Mary’:26,‘Sellina’:28,‘Zaca’:27}

import pandas as pd
import pandas as pd
a = ['Mary','Sellina','Zaca']
b = [26,28,27]
data = {'name':a,'age':b}
df = pd.DataFrame(data)
print(df)

结果如下：

      name  age
0     Mary   26
1  Sellina   28
2     Zaca   27

python代码实现转换成字典：

df1 = df.set_index(['name'])['age'].to_dict()
print(df1)
结果如下：
{'Mary': 26, 'Sellina': 28, 'Zaca': 27}

列名变成字典的key

df2 = df.to_dict(orient = 'list')
结果如下：
{'name': ['Mary', 'Sellina', 'Zaca'], 'age': [26, 28, 27]}
