For situations in which we do not know how many arguments we will pass into a function, Python provides an "unpacking operator", denoted by an asterisk in front of the parameter's variable name:
def my_unpacking_function(*many_things):
print(many_things)The function will then take how ever many arguments and put them all into a list:
In fact, print() is the most well-known example of a built-in method in Python that unpacks an arbitrary number of arguments!
