Coding with Python IDE (Pydroid 3) "Lecture day 2" - The Turtle Module of Python

Hello Friends

Designed on Canva

In my previous class, I told us why I love coding with Python, and I went further to tell us about a module in the Python library called Turtle, where we can import and design beautiful animations easily.
The turtle module of Python is very interesting, especially when you begin to create amazing designs and logos. For this week lecture, I will be showing you the basic commands and their functions in a turtle module. With this basic commands, you can direct the turtle on what to do, whereby creating something really simple and attractive.

So in this class we will be designing 2 objects, and I would be releasing the codes of my design to my students.

---

For the first part of our design today, we will be writing the code to design the image of a virus.

• Remember the first step is always to import the turtle module. I then set my background color as black which is represented in code as bg color("black").
  And I used ht() to hide the turtle pen and make it invisible.
  I then proceeded into giving the instructions for my design, where I assigned heading to begin at -90, and speed at 30.

From line 8 of my code, I instructed my design on how to display by given it a color and a pattern of movement which is represented as fd(i * 3)

---

The second design for today is the logo of Facebook, and to begin with, we import turtle as usual, I then define the def function for both left (l) and right(r) as y and x.

From 10th line of my code, I decided to to first design a blue and fill a blue round circle. To perform this, I insert blue as color, and I then inserted my desired width of the circle (3).
The blue filling was assigned to start and end between the radius of 140 and 360.

So it's time to carve out the F-like shape from our turtle,, and we know it's fill color is white.

So all I did from line 23 - 39 was to instruct the turtle on how to move **left, right, forward, and circle within a specified distance as seen in the brackets(). I ended the fill and my code was done. And the program was successfully running.

I will be sharing the codes of our above tasks today, for those interested in trying it out. And most importantly I will be equally sharing a bonus code as requested by a friend @fantvwiki.

Below are some of the source codes to our tasks today

1st object to Design(Image of a Virus)	Source Code

from turtle import *

bgcolor("black")
ht()
bk(180)
setheading(-90)
speed(30)
for i in range(180):
color("blue")
lt(i)
fd(i * 3)
color("red")
lt(i)
fd(i * 3)

done()

2nd object to Design(Facebook logo)	Source Code

from turtle import *

def l(y,x):
lt(y)
fd(x)

def r(y,x):
rt(y)
fd(x)

color("pblue")
width(3)
ht()
begin_fill()
circle(140,360)
end_fill()

rt(7)
bk(32)
color("white")

begin_fill()
l(97,98)
l(90,40)
r(90,40)
r(90,40)
l(90,34)
circle(-45,90)
fd(40)
r(90,40)
r(90,20)
circle(17,90)
fd(23)
l(90,40)
r(100,40)
r(80,30)
l(90,110)
r(90,50)
end_fill()

done()

Bonus object to Design(I ❤️ U Steemit)	Source Code

---

import turtle
st = turtle.Turtle()
turtle.Screen().bgcolor("green")

st.penup()
st.goto(-220,155)
st.pendown()

st.pencolor('white')
st.pensize(13)
st.forward(97)
st.backward(47)
st.right(90)
st.forward(166)
st.right(90)
st.forward(47)
st.backward(97)

st.penup()
st.goto(0,0)
st.pendown()

st.color("red")
st.begin_fill()
st.right(127)
st.forward(130)
st.circle(50,200)
st.right(137)
st.circle(50,200)
st.forward(130)
st.end_fill()

st.penup()
st.setpos(137, 170)
st.pendown()

st.pencolor("white")
st.right(40)
st.forward(120)
st.circle(57,170)
st.forward(120)

st.penup()
st.goto(-145,-145)
st.pendown()
st.color('white')
st.write("steemit by @preye2", font=("Courier",11,"bold"))

Conclusion

This will surely be an interesting journey friends, as I have lots of wonderful and interesting designs to teach us in this class using python. I guess they might be some challenges and questions regarding this class you might want to ask, feel free to drop them on the comment section.
