TypeError：__init __（）得到了一個意外的關鍵字參數'列'

Question

我想在wxpython中創建一個插件並運行到下面的錯誤，任何人都可以幫助理解爲什麼我遇到這個錯誤以及如何解決這個問題？

import wx 
from wx.lib.agw import ultimatelistctrl as ULC 


class TestFrame(wx.App): 
    def __init__(self): 
     wx.App.__init__(self) 
     APPNAME = 'plugin' 
     self.frame = wx.Frame(None, -1, size=wx.Size(600,700), title=APPNAME, style=wx.DEFAULT_FRAME_STYLE) 
     splitter = wx.SplitterWindow(self.frame, -1) 
     splitter.SetMinimumPaneSize(180) 
     panel1 = wx.Panel(splitter, size=wx.Size(-1, 300)) 
     commands_panel = wx.Panel(panel1, -1) 
     package_panel = wx.Panel(commands_panel, -1) 
     self.view_listctrl = ULC.UltimateListCtrl(package_panel, id=-1,columns=2,selectionType=1) 
     package_vbox.Add(self.view_listctrl, 2, wx.EXPAND | wx.ALL, 5) 
     #view_listctrl = ULC.UltimateListCtrl(package_panel, id=-1) 
     itemCount = int('2') 
     for x in range(0,itemCount): 
      view_listctrl.SetItemKind(x, 2 , 1) 

if __name__ == "__main__": 
    app = wx.App(False) 
    frame = TestFrame() 
    app.MainLoop() 

錯誤： -

Traceback (most recent call last): 
    File "listctr.py", line 26, in <module> 
    frame = TestFrame() 
    File "listctr.py", line 15, in __init__ 
    self.view_listctrl = ULC.UltimateListCtrl(package_panel, id=-1,columns=2,selectionType=1) 
TypeError: __init__() got an unexpected keyword argument 'columns' 

Answer 1

如果你看一下the documentation for the class's __init__，你可以看到它有沒有keyword argumentcolumns，可是你想傳遞一個：

self.view_listctrl = ULC.UltimateListCtrl(package_panel, id=-1,columns=2,selectionType=1) 

這基本上就是錯誤信息告訴你的。
