If I have a function def f(a, b, c, d)
and two tuples, each with two elements, is there any way to unpack these tuples so that I can send their values to the function?
f(*tup1, *tup2)
As of the release of Python 3.5.0, PEP 448 "Additional Unpacking Generalizations" makes the natural syntax for this valid Python:
>>> f(*tup1, *tup2) 1 2 2 3
In older versions of Python, you can need to concatenate the tuples together to provide a single expanded argument:
>>> tup1 = 1, 2 >>> tup2 = 2, 3 >>> def f(a, b, c, d): print(a, b, c, d) >>> f(*tup1+tup2) 1 2 2 3
