Basically I need to record the time stamp of a keystroke as well as the key pressed. From there I can put it trim it down to a record of the overall rhythm you type the password in. I'm not very far at this point so bare with me.

from tkinter import # tkinter had to be lowercase for my version

from time import time

start_time = end_time = 0

master = Tk()

e = Entry(master)

e.pack()

e.focus_set()

#* Mine

entList = [] # this will be a 2-dimentional list

entInx = 0 # I wasn't sure what this is

def key(event):

    if event.char == '\r':
        e.unbind("<Key>")
        return

    print ("pressed", repr(event.char))  # print seems to need an extra cupping
    end_time = time()
    meas_time = int(end_time-start_time)  #determine the measured time
    print ("measured time:", meas_time)
    entPair = [0,0]  # I put this here so it would restart each keypress
    entPair[0] = event.char  # place the char into pos 1 of the line
    entPair[1] = meas_time   # place the int time into pos 2 of the line
    entList.append(entPair)  # place the line into the 2d list

    print(entList)  # print the list and make Luka smile

e.bind("<Key>", key)

start_time = time()

mainloop()
