>>> root=Tk()
>>> entry=ttk.Entry(root,width=30) #character 最多可以填30个字符串。 中文的好想不对
>>> entry.pack()   #排版
>>> entry.get()  #你手动在框子里面敲你好。 他就获取他的value为你好！
‘你好！‘
>>> entry.delete(0,2) #删除第0到第二个字符。
>>> entry.get()
‘！‘
>>> entry.delete(0,END) #删除到底
>>> entry.insert(0,"Enter Your Password") #通过脚本输入
>>> entry.config(show="*")  #设置输入时候一个字符对应一个星号，比如输密码
>>> entry.get()
‘sdfdsf‘
>>> entry.state([‘disabled‘])  #让框子无法输入内容
(‘!disabled‘,)
