Python 如何向这个稍微复杂的方法调用添加参数？

我有一段代码如下所示：

rv.append(get_quest_guide_char("lindsey", **{"marker":  ["items cake_slice","items bottle pepelepsi","items apple"] for x in [1] * (game.location == lindsey.location)}))

实际上，它的工作原理是

如果game.location不等于lindsey.location，则结果调用如下所示，只传递一个参数，即lindsey参数

rv.append(get_quest_guide_char("lindsey"))

然而，如果它是真的，那么第二个参数被添加如下

rv.append(get_quest_guide_char("lindsey", marker = ["items cake_slice","items bottle pepelepsi","items apple"]))

如果结果为真，如何插入要添加的第三个条件？我试过的代码看起来像这样，但不起作用

rv.append(get_quest_guide_char("lindsey", **{"marker_sector": "right_bottom", "marker":  ["items cake_slice","items bottle pepelepsi","items apple"] for x in [1] * (game.location == lindsey.location)}))

---

其中第三个参数是marker_sector=“right_bottom”

如果我理解您的意图，请尝试以下方法：

rv.append(get_quest_guide_char("lindsey", marker_sector="right_bottom", **{"marker":  ["items cake_slice","items bottle pepelepsi","items apple"] for x in [1] * (game.location == lindsey.location)}))

它将在没有条件的情况下添加另一个kwarg，并简化代码

但是，我建议您重构这段代码，可能在append之外的变量上定义参数

if game.location == lindsey.location:
    marker = ["items cake_slice", "items bottle pepelepsi", "items apple"]
else:
    marker = None

rv.append(get_quest_guide_char("lindsey", marker_sector="right_bottom", marker=marker))
