Just use a if...else statement. I guess what you want is:

def person_detail(Person):
    Age, Sex = Person
    if Age<16:
        return 3 if Sex else 2
    else:
        return Sex

您可以使用多个if语句，if-else语句或字典：

d = {(0, 0): 0, (0, 1): 1, (1, 0): 2, (1, 1): 3}

def person_detail(Person):
    Age, Sex = Person
    return d[Age < 16, Sex]

In my opinion, you should just use a "long" if/else as suggested by @miindlek to make the different outcomes of the function clear. Also, I would suggest not just to return Sex but to return 1 if Sex else 0 , again to make exactly clear what the function returns.

But if you prefer to have a very short return line, you could also use a ternary statement like so:

return Sex + 2 if Age < 16 else Sex

Or even shorter (but not easier to understand):

return (Age < 16) * 2 + Sex
