學了兩天的gui，現在終於可以寫乙個最簡單的登入介面了，瞬間覺得python加上tkinter簡單到爆啊，如果不是專門做gui，只是輔助做做影象介面的，這簡直是逆天啊！
__author__ = 'freedom'
from tkinter import *
class reg (frame):
def __init__(self,master):
frame = frame(master)
frame.pack()
self.lab1 = label(frame,text = "user:")
self.lab1.grid(row = 0,column = 0,sticky = w)
self.ent1 = entry(frame)
self.ent1.grid(row = 0,column = 1,sticky = w)
self.lab2 = label(frame,text = "password:")
self.lab2.grid(row = 1,column = 0)
self.ent2 = entry(frame,show = "*")
self.ent2.grid(row = 1,column = 1,sticky = w)
self.button = button(frame,text = "submit",command = self.submit)
self.button.grid(row = 2,column = 1,sticky = e)
self.lab3 = label(frame,text = "")
self.lab3.grid(row = 3,column = 0,sticky = w)
self.button2 = button(frame,text = "quit",command = frame.quit)
self.button2.grid(row = 3,column = 3,sticky = e)
def submit(self):
s1 = self.ent1.get()
s2 = self.ent2.get()
if s1 == 'freedom' and s2 == '123':
self.lab3["text"] = "confirm"
else:
self.lab3["text"] = "error!"
self.ent1.delete(0,len(s1))
self.ent2.delete(0,len(s2))
root = tk()
root.title("register")
root.mainloop()
