我正在尝试制作屏幕截图功能，但每次我尝试时，它都会给我这个错误：

这是截图的部分

def Screenie(self):
file_name = Filename('whatever.png')

self.win.saveScreenshot(file_name)

  base.accept('f9', Screenie)

有人可以告诉我它有什么问题吗？我正在尝试修复它，但不知道该怎么做...

错误很明显

TypeError: Screenie() takes exactly 1 argument (0 given)

您的Screenie函数接受一个参数 ( self)，但无论调用它，都没有给出任何参数（即Screenie()，而不是Screenie(obj)）。

您选择self作为参数Screenie让我认为它是一个类方法。在那种情况下，你应该有这样的东西。

class SomeCLass(object):
    # <snip>
    def Screenie(self):
        file_name = Filename('whatever.png')
        self.win.saveScreenshot(file_name)

# Create instance
instance = SomeClass()

# Bind keypress to bound method on instance
base.accept('f9', instance.Screenie)

这可以确保self参数 ofScreenie绑定到instance对象，并且您的代码应该可以工作。
