应该可以，请参阅 https://docs.python.org/3.4/tutorial/ controlflow.html＃keyword-arguments [ ^ ]。

def arithmetic_mean(first, *values):
""" This function calculates the arithmetic mean of a non-empty
arbitrary number of numerical values """

return (first + sum(values)) / (1 + len(values))

x= [('a', 232), ('b', 343), ('c', 543), ('d', 23)]
y= [[('a', 232), ('b', 343), ('c', 543), ('d', 23)]]

What I have tried:

can it be possible by zip method or any other way possible?

It should be possible, see https://docs.python.org/3.4/tutorial/controlflow.html#keyword-arguments[^].
