1) There are four widgets- two Entry (single line textboxes), one button, one label in the program.
2) The user enters username in the first textbox. Password in the second textbox. But the password is encrypted (not shown)
3) After user hits the sign up button, the username is displayed on the label and the password is stored.
We will not store the password now, just make a dummy password entry function stub. The password can be stored in files in encrypted format or by other methods once we cover file handling in Python. Till that time, assume that the
storepassword() function stores the passwords and username automatically
We don't want others to see our passwords while we type them right? This can be achieved using the
TB1=tk.Entry(form,width = 20,show="*")
import tkinter as tk form=tk.Tk() form.title("Example of Entry widget") form.geometry('400x200') TB1=tk.Entry(form,width = 20,show="*") TB1.pack() def show(): button.config(text=TB1.get()) button=tk.Button(form,text="", command=show) button.pack() form.mainloop() show()
We already have got the specifications of the program, so now let us start building it. Here is the code for the program, commented for explaination. Be sure to give it a try first before seeing the solution.
import tkinter as tk # import the Tkinter module form=tk.Tk() # create the blank window. form.title("password manager") # set the title as password manager form.geometry('400x200') # set the default geometry of the window. TB1=tk.Entry(form, width = 20) # make an entry widget with 20 spaces for the username TB2=tk.Entry(form,show="*", width = 20) # entry widget for password and hide the keys whenever pressed. # TB1 is for username, TB2 is for password TB1.pack() TB2.pack() # pack the widgets into 'form' label=tk.Label(form,text="") # make a label to display the username def show(): #function to be executed once the button is pressed. a=TB1.get() # get username b=TB2.get() # get password if(a!="" and b!=""): label.config(text="Welcome "+a+" to python GUI",fg="Green") # display the label storepassword(a,b) # store password and username else: label.config(text="Please enter a valid username and password.",fg="Red") # blank screens def storepassword(username, password): #//Some mechanism to store password// pass #stubbed button=tk.Button(form,text="Sign Up", command=show) # setup the button button.pack() label.pack() form.mainloop() show()
Homework Run the above application (without seeing) debug and test it. Store the application in a file passwordmanager.pyw. and send me a pic on the comments below.
Well today's password manager is very secure....But tomorrow we will see a mechanism to steal the passwords by a spyware😈
So stay tuned for updates by following me.
