由于某些原因，我的代码在读取fi时没有前进

Question

基本上，我试图让程序读取文件，并采取的价值观，以绘制一些简单的形状。代码没有前进，而是将形状指定为第一行，并且不会执行任何其他操作。你知道吗

这是我要读的文件：

SQUARE
r
b
200#200
40
RECTANGLE
b
g
100#100
10
SQUARE
r
b
500#355
40
SQUARE
g
b
600#60
15
END

我试过在这个地方移动readline（），但似乎并没有解决问题，就像whileloop之前那样。你知道吗

       pygame.draw.circle(screen,(circle_colour,x,y,(diameter/2))
       pygame.display.update()

shapefile.close()

上面写着“x=int（坐标[0]） ValueError:基数为10的int（）的文本无效：“SQUARE”

我不明白为什么，但它应该打印出的形状，是假定的。你知道吗

Answer 1

您可以改用for循环：

with open( 'file', 'r') as f:
    for line in f:
        print(line)

这样您就不必使用停止条件，而且更容易调试。你知道吗
