I just wanted to post my code to request for any improvement. Originally, I did NOT come up with this code, but rather I 'improved' it visually (i.e. not performance). This code originally had several if statements that I wanted to improvise with a dictionary.
In summary, this will generate a canvas named "c" that will start blank. As the click() function is performed, it will randomly select a side on a dice while also animating it. There is an actual 'dice roll' feature to this using Tkinter's grid.
enter code here import tkinter as tk from random import randint def create_dice(): """ Creates the dice with all the sides drawn in a list. The sides are drawn by the draw_dice function. :return: dice list """ dice = list() dice.append(draw_dice('dot0')) # empty dice.append(draw_dice('dot4')) # center dot --> 1 dice.append(draw_dice('dot3', 'dot5')) # dice head 2 dice.append(draw_dice('dot2', 'dot4', 'dot6')) # dice head 3 dice.append(draw_dice('dot1', 'dot2', 'dot6', 'dot9')) # dice head 4 dice.append(draw_dice('dot1', 'dot2', 'dot4', 'dot6', 'dot9')) # dice head 5 dice.append(draw_dice('dot1', 'dot2', 'dot3', 'dot5', 'dot6', 'dot9')) # dice head 6 return dice def draw_dice(*args): """ Creates the individual heads passed in through the create_dice function. :param args: string(s) for certain dots for certain heads :return: c canvas """ w, h = 23, 23 # sets width and height x, y, r = 2, 2, 5 # sets x, y, and radius c = tk.Canvas(root, width=w, height=h, bg='white') # creates canvas c #Dictionary containing lambda functions to draw dots on canvas c dots = { 'dot0': lambda x, y, r: c, 'dot1': lambda x, y, r: c.create_oval(x, y, x + r, y + r, fill='black'), 'dot2': lambda x, y, r: c.create_oval(x + 16, y, (x + 16) + r, y + r, fill='black'), 'dot3': lambda x, y, r: c.create_oval(x, y + 8, x + r, (y + 8) + r, fill='black'), 'dot4': lambda x, y, r: c.create_oval(x + 8, (y + 8), (x + 8) + r, (y + 8) + r, fill='black'), 'dot5': lambda x, y, r: c.create_oval(x + 16, (y + 8), (x + 16) + r, (y + 8) + r, fill='black'), 'dot6': lambda x, y, r: c.create_oval(x, y + 16, x + r, (y + 16) + r, fill='black'), 'dot9': lambda x, y, r: c.create_oval(x + 16, y + 16, (x + 16) + r, (y + 16) + r, fill='black') } for arg in args: dots.get(arg)(x, y, r) # Gets the dictionary keys while passing in x, y, and r values return c def click(): """ Performs the operation of clicking the button.
