我只是不知道这是怎么回事。。。

        Food.update()

我每次都会得到以下信息：

  File "Bugs.py" line 53
    def new(self, x=False, y=False, sex=2, speed=0, generation=0, genes=[]):
                                                                           ^
Indentation Error: unindent does not match any outer indentation level

文件中可能混合了制表符和空格。可以使用python帮助检查此类错误

python -m tabnanny <name of python file>
