Question

以下python libreoffice Uno宏可以工作，但只能使用try..except语句宏允许您选择编写器文档中的文本，并将其发送到默认浏览器中的搜索引擎问题是，如果您选择单个文本，则会填充oSelected.getByIndex(0)，但如果您选择了多个文本oSelected.getByIndex(0)，则不会填充。在这种情况下，数据从oSelected.getByIndex(1)开始，oSelected.getByIndex(0)留空我不知道为什么会这样，并且想知道是否有人可以解释这种奇怪的行为。

您的代码缺少某些内容。这可以在不需要额外的try/except子句的情况下工作：

selected_strings = []
try:
    for i in range(oSelected.getCount()):
        oSel = oSelected.getByIndex(i)
        if oSel.getString():
            selected_strings.append(oSel.getString())
except AttributeError:
    # handle exception...
    return
result = " ".join(selected_strings)

回答关于＆＃34;奇怪行为的问题，＆＃34;这对我来说似乎很简单。如果第0个元素为空，则有多个选择可能需要以不同方式处理。

Pyuno索引问题，我想解释一下
