Python: combination calculator to targeted sum - validation step

I'm still struggling with this code. It's a number combination calculator to targeted sum. I need to add a validation step to see if the number already exists in my output list - if it exists then the code shouldn’t show this output. I try a lot of ideas, but I can’t solve it (for example if x in numbers etc.). Thank you so much for the advice.
def subset_sum(numbers, target, partial=):
s = sum([int(x) for x in partial])
numbers = [int(x.strip()) for x in combination.split(',')]
if s == int(target):
print("sum(%s)=%s" % (partial, int(target)))
if s >= int(target):
return
for i in range(len(numbers)):
n = numbers[i]
remaining = numbers[i + 1:]
subset_sum(remaining, int(target), partial + [n])
combination = input("combination: ")
target_sum = input("target: ")
if __name__ == "__main__":
subset_sum([combination], target_sum)

In what way didif x in numbersnot work? It sounds like a reasonable approach for checking if a number exists in a list.

@mkrieger1 Forif x in numbersI need to definexbut I don't know how to do it. Ifxis in this codenumbers = [int(x.strip()) for x in combination.split(',')]It will be x = int(x)? Thank you

@mkrieger1 For
if x in numbers I need to define x but I don't know how to do it. If x is in this code numbers = [int(x.strip()) for x in combination.split(',')] It will be x = int(x)? Thank you– Miroslav Navrátil
