Ausgabe Einstellung matplot Punkte Farbe und Form

Question

Jedes Mal, wenn ich die display_data Funktion ausführen (wenn es Daten gibt, nach dem erfolgreichen Beantwortung mindestens eine calculation_game Frage ausgeführt werden) Ich erhalte eine Fehlermeldung, die sagt:

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

Wenn ich laufe der Code ohne das "o", um die Form der Punkte zu definieren, funktioniert es gut und zeigt blaue Punkte an. Einzige Sache ist, dass ich Formen wie "o" und "v" definieren kann, weil das Diagramm Daten von mehreren Listen zeigt, wenn es fertig ist. Irgendwelche Ideen?

HINWEIS:

Es fehlen Funktionen unten. Ich habe sie hier entfernt, weil sie für die Frage nicht benötigt werden.

Verstanden, musste nur die c entfernen = Teil von plt.scatter(x, y, c="bo")
