Adding multiple numbers using a function in python

hi guys! so I am trying to add numbers using a function in python. this is the code:

def add(*numbers): for _ in numbers: return sum(_)

digits = int(input('enter numbers to add separated by comma> '))

print(add(digits))

But i get this error: Traceback (most recent call last): File "C:/Users/sani21550/PycharmProjects/MyProjects/random.py", line 60, in <module> digits = int(input('enter numbers to add seperated by comma> ')) ValueError: invalid literal for int() with base 10: '1, 2'

I seem to be suck here.

Apparently, since input takes a single value at a time (However if the input values are in a limited number, you can unpack the values like a,b = input('>>') ) passing in an unlimited amount of values require some conversions.

Since I am no master, there can be a better method, but anyways, my version does the trick

def add(numbers):
    input_data = numbers.split(",")
    final_data = []
    for _ in input_data:
        final_data.append(int(_))   
    return sum(final_data)

digits = input('enter numbers to add separated by comma> ')

print(add(digits))

To polish this even further you might need exception handling.in case a str was passed, but if it is played by the rules of int there should be no problem

Thanks!!! Your method works. I will add the exception handling to polish the code.
