I need a seven-segment clock with time.strftime. I have this for the clock:

import sys

from tkinter import *

import time



def tick():

    time_string = time.strftime("%M:%S")

    clock.config(text=time_string)

    clock.after(200, tick)



root = Tk()

clock = Label(root, font = ("times", 250, "bold"), bg="white")

clock.grid(row=0, column=1)

tick()

root.mainloop()

And this for the digits:

offsets = (

    (0, 0, 1, 0),  # top

    (1, 0, 1, 1),  # upper right

    (1, 1, 1, 2),  # lower right

    (0, 2, 1, 2),  # bottom

    (0, 1, 0, 2),  # lower left

    (0, 0, 0, 1),  # upper left

    (0, 1, 1, 1),  # middle

)



digits = (

    (1, 1, 1, 1, 1, 1, 0),  # 0

    (0, 1, 1, 0, 0, 0, 0),  # 1

    (1, 1, 0, 1, 1, 0, 1),  # 2

    (1, 1, 1, 1, 0, 0, 1),  # 3

    (0, 1, 1, 0, 0, 1, 1),  # 4

    (1, 0, 1, 1, 0, 1, 1),  # 5

    (1, 0, 1, 1, 1, 1, 1),  # 6

    (1, 1, 1, 0, 0, 0, 0),  # 7

    (1, 1, 1, 1, 1, 1, 1),  # 8

    (1, 1, 1, 1, 0, 1, 1),  # 9

    (1, 1, 1, 0, 1, 1, 1),  # 10=A

    (0, 0, 1, 1, 1, 1, 1),  # 11=b

    (1, 0, 0, 1, 1, 1, 0),  # 12=C

    (0, 1, 1, 1, 1, 0, 1),  # 13=d

    (1, 0, 0, 1, 1, 1, 1),  # 14=E

    (1, 0, 0, 0, 1, 1, 1),  # 15=F

)





class Digit:

    def __init__(self, canvas, *, x=10, y=10, length=20, width=3):

        self.canvas = canvas

        l = length

        self.segs = 

        for x0, y0, x1, y1 in offsets:

            self.segs.append(canvas.create_line(

                x + x0*l, y + y0*l, x + x1*l, y + y1*l,

                width=width, state = 'hidden'))

    def show(self, num):

        for iid, on in zip(self.segs, digits[num]):

            self.canvas.itemconfigure(iid, state = 'normal' if on else 'hidden')

But, I have no idea how to combine them.

Any improvements of the actual code will be appreciated, and if you find that something should be removed or replaced, feel free to do the change. I don't need to use this exact implementation, but this is all I have. If there is a function in a library or something to make the job a hole lot easier, please let me know.

Ok so here is my attempt to convert strftime to a 7 segment clock based on the code you provided.

My goal was to generate a list of canvas's for each digit of the formatted timestrafe string. Then on each lap of the clock simply use the Digit class to update each canvas item.

Let me know if you have any questions.

import tkinter as tk

import time

# Order 7 segments clockwise from top left, with crossbar last.

# Coordinates of each segment are (x0, y0, x1, y1) 

# given as offsets from top left measured in segment lengths.

offsets = (

    (0, 0, 1, 0),  # top

    (1, 0, 1, 1),  # upper right

    (1, 1, 1, 2),  # lower right

    (0, 2, 1, 2),  # bottom

    (0, 1, 0, 2),  # lower left

    (0, 0, 0, 1),  # upper left

    (0, 1, 1, 1),  # middle

    )

# Segments used for each digit; 0, 1 = off, on.

digits = (

    (1, 1, 1, 1, 1, 1, 0),  # 0

    (0, 1, 1, 0, 0, 0, 0),  # 1

    (1, 1, 0, 1, 1, 0, 1),  # 2

    (1, 1, 1, 1, 0, 0, 1),  # 3

    (0, 1, 1, 0, 0, 1, 1),  # 4

    (1, 0, 1, 1, 0, 1, 1),  # 5

    (1, 0, 1, 1, 1, 1, 1),  # 6

    (1, 1, 1, 0, 0, 0, 0),  # 7

    (1, 1, 1, 1, 1, 1, 1),  # 8

    (1, 1, 1, 1, 0, 1, 1),  # 9

    (1, 1, 1, 0, 1, 1, 1),  # 10=A

    (0, 0, 1, 1, 1, 1, 1),  # 11=b

    (1, 0, 0, 1, 1, 1, 0),  # 12=C

    (0, 1, 1, 1, 1, 0, 1),  # 13=d

    (1, 0, 0, 1, 1, 1, 1),  # 14=E

    (1, 0, 0, 0, 1, 1, 1),  # 15=F

)



class Digit:

    def __init__(self, canvas, *, x=10, y=10, l=20, wt=3):

        self.canvas = canvas

        canvas.delete("all")

        self.segs = 

        for x0, y0, x1, y1 in offsets:

            self.segs.append(canvas.create_line(x + x0*l, y + y0*l, x + x1*l, y + y1*l, width=wt, state='hidden'))



    def show(self, num):

        for iid, on in zip(self.segs, digits[num]):

            self.canvas.itemconfigure(iid, state='normal' if on else 'hidden')



def tick():

    global canvas_list

    for ndex, num in enumerate(time.strftime("%M:%S").replace(':', '')):

        Digit(canvas_list[ndex]).show(int(num))

    root.after(1000, tick)



root = tk.Tk()

clock_frame = tk.Frame(root)

clock_frame.grid(row=1, column=0)



canvas_list = 



time_col = 0

canvas_count = 0



for i in range(5):

    if i == 2:

        tk.Label(clock_frame, text=":", font = ("times", 40, "bold")).grid(row=0, column=time_col)

        time_col += 1

    else:

        canvas_list.append(tk.Canvas(clock_frame, width=30, height=50))

        canvas_list[canvas_count].grid(row=0, column=time_col)

        canvas_count += 1

        time_col += 1



tick()

root.mainloop()

Keep in mind the OP's code was just looking at min/sec so this clock will reflect that.
