求解答一下，cannot unpack non-iterable TextCtrl object

问题相关代码，请勿粘贴截图

import wx
class MyFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,title="新的一天",pos = (100,100),size = (400,400))
        panel = wx.Panel(self)
        self.title = wx.StaticText(panel,label = "账户登录",pos = (200,20))
        font = wx.Font(20,wx.DEFAULT,wx.NORMAL,wx.NORMAL)
        self.title.SetFont(font)
        self.user = wx.StaticText(panel,label = "用户名：",pos = (50,150))
        self,user_text = wx.TextCtrl(panel,pos = (100,150),size = (150,50),style = wx.TE_LEFT)
        self.password = wx.StaticText(panel,label = "密码：",pos = (50,200))
        self,password_text = wx.TextCtrl(panel,pos = (100,200),size = (150,50),style = wx.TE_PASSWORD)




if __name__ == '__main__':
       app = wx.App()
       frame = MyFrame(parent = None,id = -1)
       frame.Show()
       app.MainLoop()

运行结果及报错内容

Traceback (most recent call last):
  File "C:/Users/jmy/Desktop/py练习/demof21_11_28.py", line 16, in <module>
    frame = MyFrame(parent = None,id = -1)
  File "C:/Users/jmy/Desktop/py练习/demof21_11_28.py", line 10, in __init__
    self,user_text = wx.TextCtrl(panel,pos = (100,150),size = (150,50),style = wx.TE_LEFT)
TypeError: cannot unpack non-iterable TextCtrl object

我想要达到的结果

第10行报错，TextCtrl对象不是可迭代对象，无法拆包为两个变量。
应该是self.user_text ,将逗号改成点号。
