    您需要阅读更多关于 python 中的类：https ://docs.python.org/3/tutorial/classes.html

    您没有正确使用它。这是您更正的程序：

    name = input()
meth = input()

class Player:
    def __init__(self, name):
        self.name = name
    def play(self, name):
        return print(name, 'is playing')
    def ff(self, name):
        return print(name, 'is fast forward')
    def rew(self, name):
        return print(name, 'is rewind')
    def stop(self, name):
        return print(name, 'is stop')
pl = Player(name)
if meth == 'play':
    pl.play(name)
elif meth == 'ff':
    pl.ff(name)
elif meth == 'rew':
    pl.rew(name)
elif meth == 'stop':
    pl.stop(name)

    但最好这样做：

    name = input()
meth = input()
class Player:
    def __init__(self, name):
        self.name = name
    def play(self):
        return print(self.name, 'is playing')
    def ff(self):
        return print(self.name, 'is fast forward')
    def rew(self):
        return print(self.name, 'is rewind')
    def stop(self):
        return print(self.name, 'is stop')
    def logic(self, meth):
        if meth == 'play':
            self.play()
        elif meth == 'ff':
            self.ff()
        elif meth == 'rew':
            self.rew()
        elif meth == 'stop':
            self.stop()
pl = Player(name)
pl.logic(meth)
