'''TKINTER:'''
'''
Welcome to tkinter, the canvas part of Python. With tkinter you can draw lines and \
shapes such as ovals, arcs and rectangles. You can also create some wild digital \
string-art designs with for-loops. With tkinter you can also create buttons and input \
boxes. We will get into all this and more about tkinter, the fun part of Python programming.

# Let's create a simple tkinter window. Type and execute/run this tkinter program
# example below and see what happens.

from tkinter import*

# This simple tkinter program will create an empty window, which is 500 X 500 pixels.
# Type and execute/run this tkinter program example below and see what happens.

from tkinter import*

# So far the tinkter window is empty; no canvas colours or anything, but a simple
# grayed out, empty tkinter window. Now, let's add colour to our empty tkinter window
# to sort of see where we are going with tkinter. Type and execute/run the tkinter
# program example below and see what happens when we add the colour black to our
# empty tkinter window.

from tkinter import*

root=Tk()

draw=Canvas(root,height=500,width=500,bg='black')

draw.pack()

root.mainloop()

# Now that we have our empty tkinter window, which is now a black, empty tkinter
# window. Let's add a simple, blue diagonal line drawing inside our black, empty
# tkinter window and see what happens when you execute/run the tkinter program
# example below.

from tkinter import*

root=Tk()

draw=Canvas(root,height=500,width=500,bg='black')

# Note: hexadecimal values can also be used with the tkinter canvas colour as well as
# the tkinter graphics colour scheme alike. All hexadecimal values in Python start with
# the '#' number sign, then preceding with a six digit hexadecimal number to the right,
# for example '#000000' = black, '#ffffff' = white. See below, a basic hexadecimal RGB
# colour codes list as follows:

# Black = '#000000'
# White = '#ffffff'
# Red = '#ff0000'
# Green = '#00ff00'
# Blue = '#000fff'
# Yellow = '#fff000'
# Pink = '#ff00ff'
# Cyan = '#00ffff'

# Now let's add another diagonal line in the tkinter window and colour it red and
# change the background colour to the hexadecimal colour code, black. type and
# execute/run the tkinter program example below and see what happens.
