python - 另一个列表理解问题

Question

我有这个:

    if Setting["Language"] == "en":
        f.m_radioBox3.SetSelection(0)
    elif Setting["Language"] == "pt":
        f.m_radioBox3.SetSelection(1)
    elif Setting["Language"] == "fr":
        f.m_radioBox3.SetSelection(2)
    elif Setting["Language"] == "es":
        f.m_radioBox3.SetSelection(3)

然后我这样做了:

    Linguas = ["en","pt","fr","es"]
    a = 0
    for i in Linguas:
        if i == Setting["Language"]:
            f.m_radioBox3.SetSelection(a)
        a += 1

是否可以进一步简化它并使其成为一行？

Answer 1

Linguas = ["en","pt","fr","es"]

if Setting["Language"] in Linguas:
    f.m_radioBox3.SetSelection(Linguas.index(Setting["Language"]))

或者你可以用字典来做:

Linguas = {"en":0,"pt":1,"fr":2,"es":3}

if Setting["Language"] in Linguas:
    f.m_radioBox3.SetSelection(Linguas[Setting["Language"]])
