TypeError缺少3个必需的位置参数

Question

我有一个tkinter按钮，当按下该按钮时会调用命令“ nadirpatch”。 当我按下按钮时，出现以下错误：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/__init__.py", line 1699, in __call__
    return self.func(*args)
TypeError: nadirpatch() missing 3 required positional arguments: 'photoSphere', 'nadir', and 'photospherePath'

这是我的“ nadirpatch”代码：（变量已经定义）

def nadirpatch(photoSphere, nadir, photospherePath):
    for photospherePath in photospherePath:
        photoSphere = Image.open(photospherePath) 
        nadir = Image.open(nadirPath)
        nadir = nadir.resize((photoSphere.size), resample=0)
        photoSphere.paste(nadir, (0, 0), nadir) 
        photoSphere.save((stitchedPath+"/patchedsphere"+(str(fileNum+1))+".jpeg"), "JPEG")
        fileNum +=1

谢谢！

您需要在Button定义中传递参数，如下所示：

# Sample code
button = Tk.Button(master=frame, text='press', command= lambda: nadirpatch(photoSphere, nadir, photospherePath))
