由于某种原因，每次我按现在的方式运行代码时，都会出现此错误：

ParseError: bad input on line 103

但是我什么都试过了，还是不行。有人可以帮忙吗？ - 仅供参考，第 103 行是：

for colorados in ("BlanchedAlmond", "PeachPuff", "Azure", "MistyRose", "LightPink", "PaleVioletRed", "MediumOrchid", "Sienna", "SandyBrown", "NavajoWHite2", "Bisque", "LavenderBlush2","Thistle", "BlueViolet", "Magenta", "Maroon1", "DeepPink2", "Brown4", "SaddleBrown", "Dark Olive Green", "DarkSeaGreen", "LightSeaGreen", "LimeGreen", "Gold", "DarkGoldenrod", "DarkOrange", "tan", "wheat", "aliceblue", "cyan", "steelblue"):

就上下文而言，这是一个 Python Turtle 代码，旨在以圆形的一般形状创建几个不同的形状，并且第 103 行中的所有这些字符串都是颜色阴影。

【问题讨论】：

您在上一行的末尾缺少)。

如果您在其他问题中搜索该错误消息，您会发现这几乎总是原因。

【参考方案1】：

您在第 100 行的 time.sleep(1 中缺少结束 ) 您还忘记使用 scr.colormode(255) 来允许 0 到 255 之间的 RGB 值
