TypeError 接受 2 个位置参数，但给出了 3 个

Question

我正在开发一个程序，将图像转换为 .mcfunction 文件，用于我的世界基岩版和 java 版。 在我的程序中，我使用 for 循环在image.getpixel中插入 x 和 y 坐标。 然而，整个晚上我都被错误困住了

TypeError: getpixel() 接受 2 个位置参数，但给出了 3 个

并且不确定是什么原因造成的。 我以前没有这个问题，但我最近添加了一个旋转图像预览的功能，突然这开始发生了。 这是我的程序：

好的，所以错误来了，因为你写了

imgfcalc.getpixel(i,j)

并且根据错误， getpixel方法仅采用两个位置参数。 但是你给了 i ， j 是两个位置参数，一个位置参数是imgfcalc(self) 。 因此，您总共给出了 3 个参数并且您需要删除一个参数。 该函数可能会采用元组/列表中的那些 i,j 参数尝试将参数作为 (i,j) 而不是 i,j
