On the eve of Valentine's day , There are also many private letters from friends Dream, Can you help me take it off and place an order , Issue a confession artifact ！ Many friends used this last year ： python Cross year declaration artifact – You deserve it ！, This year, he successfully joined the sea king , Thank you in succession Dream, Ask me if there is anything else good . A senior old sea king's autobiography （ No ）： There are good things ！ There are still a lot of it ！
So I took the risk of not spending Valentine's day with my girlfriend ,Dream The latest confession artifact was made overnight . It's coming to meet the needs of our friends ： Valentine's day exclusive gift , Give it to her who you love most ~ If you don't talk much, see the effect first ：

Now let's talk slowly , Please take a seat in the front row , Take your own popcorn （ give the thumbs-up + A collection is equivalent to a popcorn ）

Two 、 The production process

1. Interactive interface

Here we use the definition clear_screen() Function to clear the screen for each animation , Conducive to the next animation display . The overall situation applies turtle library 、time Time bank 、random Random library , as well as tkinter Kuhe threading library .
Installation method ：cmd And then directly pip install turtle( The name of the required Library )

#  Realization of clean screen 
def clear_screen():
    turtle.penup()             # Brush up 
    turtle.goto(0,0)        # Locate the （0,0）
    turtle.color('white')
    turtle.pensize(800)         # Brush thickness 
    turtle.pendown()           # The paintbrush falls 
    turtle.setheading(0)        # Set orientation 
    turtle.fd(300)       # Forward 
    turtle.bk(600)      # back off 

#  Initialize the turtle's position 
def go_start(x, y, state):
    turtle.pendown() if state else turtle.penup()
    turtle.goto(x, y)

# Draw line ,state When true, the turtle returns to the origin , When it's false, it doesn't go back to the original starting point 
def draw_line(length, angle, state):
    turtle.pensize(1)
    turtle.pendown()
    turtle.setheading(angle)
    turtle.fd(length)
    turtle.bk(length) if state else turtle.penup()
    turtle.penup()

2. Draw a little man who emits love

Here are some operations of turtle drawing ：

#  Draw a picture of a little man who radiates love 
def draw_people(x, y):
    turtle.speed(0)
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.pensize(2)
    turtle.color('black')
    turtle.setheading(0)
    turtle.circle(35, 360)
    turtle.penup()
    turtle.pensize(3)
    turtle.setheading(90)
    turtle.fd(45)
    turtle.setheading(180)

4. Romantic pop-up painting

It's used here tkinter Module to draw a small pop-up window , Finally, I use for Loop to realize the repeatability and randomness of pop-up window , This is also the biggest innovation I think ！ A lot of surprises , Full of heart and romance , Ha ha ha .

def dow():
    window = tk.Tk()
    width = window.winfo_screenwidth()
    height = window.winfo_screenheight()
    a = random.randrange(0, width)
    b = random.randrange(0, height)
    window.title(' baby ！')
    window.geometry("200x50" + "+" + str(a) + "+" + str(b))
    tk.Label(window,
             text=' I love you baby ！',  #  Label text 
             bg='pink',  #  The background color 
             font=('..', 17),  #  Font and font size 
             width=18, height=2  #  Label length and width 
             ).pack()  #  Fixed window position 
    window.mainloop()



number=[3,2,1]    # Store the countdown number on the display screen 1,2,3

if __name__ == '__main__':
    turtle.setup(900, 500)     # Adjust the size of the canvas 
    for i in number:
        draw_0(i)
        clear_screen()
    draw_1()
    clear_screen()
    draw_2()
    clear_screen()
    draw_3()
    clear_screen()
    draw_4()
    time.sleep(5)
    #  Pop up settings 
    threads = []
    for i in range(200):  #  Number of cartridges required 
        t = threading.Thread(target=dow)
        threads.append(t)
        time.sleep(0.01)
        threads[i].start()
