在Python中從數據框創建字典

Question

我想從我的數據框中創建字典。數據幀是這樣的：

Vehical | Brand | Model Name 
car  | Suzuki | abc 
car  | Honda | def 
bike | Suzuki | xyz 
bike | Honda | asd 

我想我的字典，如：

{car : {Suzuki : abc, Honda : def}, bike : {Suzuki : xyz, Honda : asd}} 

Answer 1

你能做到這樣：

In [28]: df.pivot(index='Vehical', columns='Brand', values='Model Name') 
Out[28]: 
Brand Honda Suzuki 
Vehical 
bike  asd xyz 
car  def abc
