Python: 出现语法错误。可能是因为PIL库安装不正确

Question

width, height = img.size
total = 0
for row in range(width):
    for col in range(height):
        # This will save the RGBA values of the pixel
        red, green, blue, alpha = img.getpixel( (row, col) )
        new_red = red + new_red
        new_green = green + new_green
        new_blue = blue + new_blue
        total = 1 + total

average_red = new_red/total
average_green = new_green/total
average_blue = new_blue/total
img.putpixel((row, col,), (average_red, average_green, average_blue, 255)
img.show()

我在使用它时遇到语法错误。我猜测可能是PIL模块安装不正确造成的。

有人知道是否是这种情况吗？

如果是这样，有人可以指导我找到有关如何在 Mac OSX 中安装它的安装指南吗？

Answer 1

您在

末尾缺少一个 )

img.putpixel((row, col), (average_red, average_green, average_blue, 255)

应该是

img.putpixel((row, col), (average_red, average_green, average_blue, 255))
