我希望能够使用两个搜索栏同时更新两个列表框

Question

我希望能够使用两个列表同时更新两个列表框，这两个列表在两个搜索栏中具有相同数量的项目。 第一个列表框有一个包含字母的列表，第二个列表框有直接对应于这些字母的数字，例如 A 与 1 对应，B 与 2 对应，依此类推。 我希望能够在左侧的第一个输入框中键入“a”，并且在第一个列表框中仅显示“a”，在第二个列表框中仅显示“2”，或者在列表框中键入“2”第二个框将显示第二个列表框中具有“2”的所有项目，因此第一个列表框也仅显示与此项目对应的项目。 我已经能够做到一个输入框可以处理但只有两个列表框之一，但我希望两者同时更新。

一种可能的解决方案是 zip 包含数据的列表，将元素添加到列表并将其传递给update(x)() function。

zip() function 会从多个容器中获取相似索引的元素。

而既然要相应更新，那就是go的方法。

def checkinlist1(e):  
    ....
        listdata1 = []
        listdata2=[]
        for item,item2 in zip(databaselist1,databaselist2):  # loops though the list
            if searchtyped.lower() in item.lower():
                listdata1.append(item)
                listdata2.append(item2)
    update2(listdata2)
    update1(listdata1)

....
def checkinlist2(e):  
        ....
        listdata2 = []
        listdata1=[]
        for item,item2 in zip(databaselist2,databaselist1):  # loops though the list
            if searchtyped.lower() in item.lower():
                listdata2.append(item)
                listdata1.append(item2)
    update1(listdata1) 
    update2(listdata2)
