I have a python function which takes as input an arbitrary number of parameters. I beleive this is implemented via *args (thanks @Anurag Wagh for pointing this out). I would like to be able to pass to it a list of values. Here is the specific code I have:
from sympy import solve_poly_system, symbols
x,y,z = symbols('x y z')
print(solve_poly_system([y**2 - x**3 + 1, y*x], x, y))
Instead of passing x and y to solve_poly_system, I want to be able to pass it a list L something like so:
print(solve_poly_system([y**2 - x**3 + 1, y*x], L))
where L = [x,y].
Is this possible? Please note, although I am interested in the specific case of the solve_poly_system function, I am more broadly interested in the passing a list to any function in python that takes an arbitrary number of inputs.
To put this another way, I want to know how to pass a list of values to a function which takes *args as input. In particular I am interested in the case where the length of the list is not known until run time and may change during run time.
From your question, it looks like you know how to use *args in function definition and you are looking for a way to pass all the elements of a list to that function regardless of the length of the list. If that's your question, then here's your answer:
def function(x, *args):
print(x)
print(args)
x = 10
l = [5, 6, 7, 8]
function(x, *l)
Output:
10
(5, 6, 7, 8)
