在 python 函数中传递和使用动态 arguments

Question

I do have a function that receives a list and some parameters, later this function creates a linear equation from the parameters and the list provided.

def modelFunction(data, a, b, c, offset):
    f = (data[0] * a) + (data[1] * b) + (data[2] * c) + offset
    return f

I would like to create the parameters dinamically and create the linear equation dinamically also. The final objective should be that I can create a different function with a different number of parameters every time I call it. Example: If I need to create a linear equation with 2 parameters and it's intercept then it creates a function like:

data is a list of len=2

def modelFunction(data, a, b,offset):
    f = (data[0] * a) + (data[1] * b) + offset
    return f

If I need to create a linear equation with 3 parameters and it's intercept then it creates a function like:

data is a list of len=3

def modelFunction(data, a, b, c, offset):
    f = (data[0] * a) + (data[1] * b) + (data[2] * c) + offset
    return f

I believe the * operator might help me but hadn't been able to figure it out

Answer 1

Equal length checking omitted for brevity:

def modelFunction(data, *coeffs):
    return sum(d * c for d, c in zip(data, coeffs)) + coeffs[-1]
