Python小白在Python3.6中运行书上代码报错，该如何解决？

代码内容：
import wx
def hello(event):
print (“Hello,word!”)


app=wx.App()

win=wx.Frame(None,title=“Hello,wxPython!”,
size=(200,100))


button=wx.Button(win,label=“Hello”)
button.Bind(wx.EVT_BUTTON,hello)
win.show()
app.MainLoop()


错误提示：
Traceback (most recent call last):
File “C:\Users\infin\Desktop\Hello Word!.py”, line 12, in <module>
win.show()
AttributeError: ‘Frame’ object has no attribute 'show’
