Python unittest DDT and if there are changes, how to do after the change of parameters-CodePudding

DDT pass parameters if have change, how to do after the change of parameters?

For example, the following code after I want to change a value, printed after the change of a value, can be achieved?

 
Data_dict=[{10, 'a' : 'b' : 20, 'c' : 30}, {11, 'a' : 'b' : 21, 'c' : 31}, {12, 'a' : 'b' : 22, 'c' : 32}] 

@ DDT. DDT 
The class MyClass (unittest. TestCase) : 

Data_dict @ DDT. Data (*) 
Def test1 (self, data) : 
Print (data) 
Data [' a ']=22 
Print (data_dict) 

If __name__=="__main__ ': 
Unittest. The main ()
