Create a new class instance with arguments stored in a list in Python

Question

I'm wondering if there is a way to use an argument list for class initialization in Python.

For example in this class:

class TestClass:
    def __init__(self, a, b, c):
        self.result = a + b + c

t = TestClass(1, 2, 3)
print(t.result)
# 6

I use arguments a, b, c. If I have those arguments stored in list l = [1, 2, 3], can I somehow apply TestClass() constructor to this list?

I'm looking for something similar as an apply function in Common Lisp, that would work with Python class constructors.
