TTurtle

The travails of Turtle: Still trying for a generic Valentine's message.

import turtle
import random

screen = turtle.Screen()
screen.setup(width=680, height=680)
screen.bgcolor("midnightblue")
image = "Choco.gif"
screen.bgpic(image)
my_t = turtle.Turtle()
my_t.hideturtle()
my_t.speed(1)
col = ["white", "aquamarine", "yellow"]
my_t.pencolor(random.choice(col))
my_x = [-270,-100]
my_y = [200, 225]
my_t.pu()
my_t.setpos(random.choice(my_x), random.choice(my_y))
my_t.pd()
siz = [18, 22, 26]
look = ["bold", "italic", " "]
my_t.write("SWEETS for my Sweetie...", font = ("Times_Nr", random.choice(siz), random.choice(look)))
my_t2 = turtle.Turtle()
my_t2.color('orange', 'khaki')
my_t2.shape('turtle')
my_t2.pensize(3)
my_t2.hideturtle()
my_t2.pu()
my_t2.goto(-250, 300)
my_t2.showturtle()
my_t2.pendown()
my_t2.forward(500)


screen.mainloop()

Quantum

Found an awesome vid on quantum physics, this morning. Thought

I would share:

A neat way to get clear about the difference between classical and quantum

physics is to look at two versions of the (Young's) double slit experiment.

An an experiment in classical physics at the beginning of the 19th century,

it demonstrates that light is a wave. As a recent experiment, done with individual

electrons, it shows that the quantum has to cross both slits at once, and interfere

with itself. Clean...

Valentinus

Allowed myself a day of reading, as I mull on what my Valentine's Day

turtle project should be. Valentine'sDay is St-Valentine's day in French, and

harps back to the early Christian martyr of the thrid century whose Feast Day is

February 14. Interestingly, there was prior to that in Rome a pagan feast at the date,

where an animal was sacrificed to mark the end of the year. The new year started

on March1.

Valentinus was a given name for male children in Rome; it means strong and

valorous. The first historical Valetinus was a gnostic theologian in the second century AD.

There is some confusion about the precise tennets of Gnosticism, but it existed at the

same time as very early Christianity and overlapped with it. From Wikipedia:

Traveller

There were repurcussions: The US Fed raised the Bank rate

by a modest .25 points yesterday, but did indicate it expected

a further such raise down the road. This morning we find that

the Bank of England has raised its rate by .50 to 4%. and that

the Eurozone rate was also up .50 to 3% with an expected further

.50 raise next month.

Definitions

Below, one sees clearly the difference between the class and the base class. Shape

is called from the base class Turtle - super(shape = 'anything')- whereas color is from

RawTurtle.

from turtle import TurtleScreen, RawTurtle
from tkinter import*
import random

root = Tk()
c1 = Canvas(root, width= 300, height=400)
c1.pack()
screen = TurtleScreen(c1)
screen.bgcolor('sky blue')

def go():
    t1.forward(130)

class turtle(RawTurtle):
    def _init_(self, color):
        super().__init__(shape='shape')
        self.TurtleScreen = 'c1'
        self.color = color

my_list1 = ['Hello!', 'Bonjour!', 'Guten Tag!', 'Hola!']
message1 = random.choice(my_list1)

my_list2 = ['Good-Bye!','Au revoir!', 'Auf Wiedersehen!', 'Chao!']
message2 = random.choice(my_list2)

t1 =turtle(screen, 'turtle')
t1.color('blue', 'red')
t1.pu()
t1.goto(-20, 30)
t1.pd()
t1.write(message2, font=('Ink_Free', 20, 'bold'))
t1.pu()
t1.backward(50)

screen.onkey(fun=go, key="Up")
screen.listen()
root.mainloop()

screen.exitonclick()

Next, I need to define write(message) as a class method ie on the class and not

on any particular instance of it...

* * *

rom turtle import TurtleScreen, RawTurtle
from tkinter import*
import random

root = Tk()
c1 = Canvas(root, width= 300, height=450)
c1.pack()
screen = TurtleScreen(c1)
screen.bgcolor('sky blue')

def go():
    t1.forward(130)

class turtle(RawTurtle):
    def _init_(self, color,message ):
        super().__init__(shape='shape')
        self.TurtleScreen = 'c1'
        self.color = color
        self.message = 'message'
        self.f = write(message)


my_list1 = ['Hello!', 'Bonjour!', 'Guten Tag!', 'Hola!']
message1 = random.choice(my_list1)

my_list2 = ['Good-Bye!','Au revoir!', 'Auf Wiedersehen!', 'Chao!']
message2 = random.choice(my_list2)

@classmethod
def write(turtle, message):
    turtle.write(message)
    turtle.style = ('Ink_Free', 20, 'bold')

t1 =turtle(screen,'turtle')
t1.color('blue', 'red')
t1.pu()
t1.goto(-20, 30)
t1.pd()
t1.write(message1,font='style')
t1.pu()
t1.goto(40,-10)
t1.pd()
t1.write(message2,font ='style')
t1.pu()
t1.backward(150)

screen.onkey(fun=go, key="Up")
screen.listen()
root.mainloop()

screen.exitonclick()
