我有这个功能:

def make_happiness_table("word-happiness.csv"):
   ''' make_happiness_table: string -> dict
      creates a dictionary of happiness scores from the given file '''

   return {}

但是在尝试运行程序时我一直遇到语法错误.

File "happiness.py", line 13
def make_happiness_table("word-happiness.csv"):
                                            ^
SyntaxError: invalid syntax

我怎样才能解决这个问题？
