Easy password box in Python

background

Since it was necessary to enter the user's password when executing a Python command, I created a pop-up to enter the password with a simple code.

reference

Tkinter has little information and is a little inconvenient to use, but posted by nnahito is well organized, so I think it will be helpful.

code

The operation was done with python 2.7.10. Tkinter is built into the python standard, so you don't need to install it. Since the code is minimal, if you want to change the GUI, please change the code below.

# -*- coding: utf-8 -*-
import Tkinter

class PswdBox(Tkinter.Tk):
    def __init__(self):
        Tkinter.Tk.__init__(self)
        self.title('Enter password')
        self.ent = Tkinter.Entry(self, show='*')
        self.ent.pack()
        self.lbl = Tkinter.Label(self, foreground='#ff0000')
        self.lbl.pack()
        self.btn = Tkinter.Button(self, text='Submit', command=self.submit)
        self.btn.pack()
        #Define the correct password here or import from a file, etc.
        self.correct_pass = 'pass'

    def submit(self):
        self.pswd = self.ent.get()
        if self.pswd == self.correct_pass: #correct
            self.destroy() #close the window
        else: #Wrong
            self.lbl['text'] = 'Try again!'
            print(self.pswd)


if __name__ == '__main__':
    pb = PswdBox()
    pb.mainloop()
    print(pb.pswd)
