PYTHON语法错误吗？

Question

I keep getting an "invalid syntax" message when I try to run this program. It highlights "age" in red after the "else" statement. I'm not sure what I did wrong.

age = float(input('How old are you? '))
citizen = float(input('How long have you been an American citizen? '))
if age >= 30 and citizen >= 9:
    print('You are eligible to become a US Senator and a House Representative!')
else age < 30 >= 25 and citizen < 9 >= 7:
    print('You are only eligible to become a House Representative.')
if age < 25 or citizen < 7:
    print('You are not eligible to become a US Senator or a House Represenatative.')

Answer 1

else age < 30 >= 25 and citizen < 9 >= 7:

is a syntax error. You can't have anything other than a : after an else statement.

Maybe you wanted an elif clause ¹ ?

elif 30 > age >= 25 and 9 > citizen >= 7:
    ...

^{1 Note that I also had to switch around your values a bit to make sense of the operator chaining that you were doing ...}

Answer 2

else age < 30 >= 25 and citizen < 9 >= 7:的else应当更改为elif 。
