如何定义Function参数随输入文件变化？

Question

I have a CBR function which takes 4 parameters like
CBR (w1,w2,w3,w4,x_train,y_train) w1 to wn changes according to the input file. w1 to wn are weights of independent parameters. Thus, according to the input file and the size of the input parameters, w1 to wn changes (N size of input parameters). How can I define such a function? Could you give me an example? Thanks

Answer 1

To pass a variable number of arguments you can use

def CBR(x_train, y_train, *args):
   ...

The special syntax *args is used to pass a variable number of arguments to a function.

The syntax is to use the symbol * to take in a variable number of arguments; by convention, it is often used with the word args but you can use w if you prefer.
