PYTHON语法错误无效？

PYTHON Invalid Syntax Error?

当我试图运行这个程序时，我一直收到一条"无效语法"消息。它在"else"语句后以红色突出显示"age"。我不知道我做错了什么。

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.')

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

是语法错误。在else语句之后，不能有除:之外的任何内容。

也许你想要一个elif第1条？

1 2	elif 30 > age >= 25 and 9 > citizen >= 7: ...

1请注意，我还必须稍微转换一下您的值，以便理解您正在进行的运算符链接…
