大神求解，为何无效，怎么弄正确？

问题
  File "C:\python\.py\python15\kjwxframe.py", line 5
    wx.Frame.__init__(self,parent,id,title="创建Frame",pos=(100,100),size=(300,300)))
                                                                                  ^
SyntaxError: invalid syntax


代码
import wx

class MyFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,title="创建Frame",pos=(100,100),size=(300,300)))

app = wx.App()
frame = MyFrame(parent=None,id=-1)
frame.Show()
app.MainLoop()
