Seven Segment Digits Clock With The System Time In Python Tkinter With Strftime

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') c

Solution 1:

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
)

classDigit:
    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'))

    defshow(self, num):
        for iid, on inzip(self.segs, digits[num]):
            self.canvas.itemconfigure(iid, state='normal'if on else'hidden')

deftick():
    global canvas_list
    for ndex, num inenumerate(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 = 0for i inrange(5):
    if i == 2:
        tk.Label(clock_frame, text=":", font = ("times", 40, "bold")).grid(row=0, column=time_col)
        time_col += 1else:
        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.
