求助:在wxpython中使用if 条件，运行结果不正确。求高手帮我，谢谢。
程序代码：import wx
import datetime
num=19.2
class MyFrame(wx.Frame):
def __init__(self,parent,id):
wx.Frame.__init__(self,parent,id,'地铁充值',size=(280,300))
panel=wx.Panel(self)
self.zhan=wx.StaticText(panel,label='请输站名')
self.zhan1=wx.TextCtrl(panel,style=wx.TE_LEFT)
hsize=wx.BoxSizer(wx.HORIZONTAL)
hsize.Add(self.zhan,proportion=0,flag=wx.ALL,border=10)
hsize.Add(self.zhan1,proportion=0,flag=wx.ALL,border=10)
self.mony=wx.StaticText(panel,label='充值金额')
self.mony1=wx.TextCtrl(panel,style=wx.TE_PROCESS_ENTER)
self.Bind(wx.EVT_TEXT_ENTER, self.text_enter,self.mony1)
hsize1=wx.BoxSizer(wx.HORIZONTAL)
hsize1.Add(self.mony,proportion=0,flag=wx.ALL,border=10)
