我已经创建了一个TreeView，但是当我调用特定的函数时，我希望能够隐藏某些列。所以这个TreeView最初是创建的，但是当我调用一个函数时，可以说除了[trackArtist]之外所有的列都被隐藏了。我该怎么做呢？我可以通过在函数中重写TreeView的部分（我想要出现的列）来使它工作，但这看起来非常多余。

self.tree.configure(yscrollcommand=ysb.set)
self.tree.configure(xscrollcommand=xsb.set)
self.tree["columns"]=("trackNumber", "trackTitle", "artistCat", "artistDisplay", "trackArtist", "album",
"albumLabel", "composer", "year", "trackDuration", "albumAsin", "albumItunes", "ISRC",
"filename", "albumCoverName", "notes")

您应该可以使用
这样做 self.tree["displaycolumns"]=("artistCat", "artistDisplay")
在Documentation上找到。
要显示除一个以外的所有内容，您可以在for循环中构建它
exclusionlist=[...]
displaycolumns=[]
for col in tree["columns"]:
if not "%s"%col in exclusionlist:
displaycolumns.append(col)
tree["displaycolumns"]=displaycolumns
查找以下不会弄乱数据的工作代码。 仅使用tree["displaycolumns"]=[...]
