对象不带参数

Question

当我运行以下代码时出现上述错误：

class Song(object):
    def _init_(self,lyrics):
        self.lyrics=lyrics

happy_bday = Song([ "happy birthday to you.",
                    "i don't want to get sued.",
                    "so i will stop right here."])

当我从 PowerShell 运行它时，我得到这个错误：

Traceback (most recent call last):
 File "qa.py", line 12, in <module>
    "so i will stop right here".])
TypeError:object() takes no parameters

Answer 1

您的 init 方法需要两边 2 _，而不仅仅是 1

def __init__(self, lyrics):

Answer 2

再次检查您的源代码。错误消息和您的来源之间存在差异。你的消息来源说：

"so i will stop right here."])

但您的错误消息显示：

"so i will stop right here".])

引号外而不是引号内的句点很重要！
