Question

每当我运行display_data函数（在成功回答至少一个calculation_game问题后有数据运行时），我会收到错误消息：

"ValueError: to_rgba: Invalid rgba arg "o"
to_rgb: Invalid rgb arg "o"
could not convert string to float: 'o'"

当我在没有＆＃34; o＆＃34;的情况下运行代码时定义它工作正常的点的形状并显示蓝点。唯一的问题是我希望能够定义诸如＆＃34; o＆＃34;之类的形状。和＆＃34; v＆＃34;因为该图将在完成后显示来自多个列表的数据。有什么想法吗？

注意：

下面缺少功能。我在这里删除了它们，因为这个问题不需要它们。

Answer 1

知道了，只需从plt.scatter(x, y, c="bo")

中删除c =部分

问题设置matplot指向颜色和形状
