GUIDED BY: PROF. PALLAVI MANKAR GRAPHICS USING PYTHON What is Turtle Graphics? Logo is an educational programming language designed in 1967 by Daniel G. Bobrow, Wally Feurzeig, Seymour Papert and Cynthia Solomon. Today the language is remembered mainly for its use of “Turtle Graphics” which commands for movement and drawing produced line graphics on screen with a small pointer called a “Turtle”. Turtle in Python
To make graphic designs using Python, imagine a robotic turtle
starting at (0,0) in the x-y plane. Execute the import turtle Python command. This will import the turtle library so as to use the functions already present in the library. We can use these functions to create our own graphic design. Functions in Turtle Module Method Parameter Description Turtle() None Creates and returns a new turtle object forward() amount Moves the turtle forward by the specified amount backward() amount Moves the turtle backward by the specified amount right() angle Turns the turtle clockwise left() angle Turns the turtle counterclockwise penup() None Picks up the turtle’s Pen pendown() None Puts down the turtle’s Pen up() None Picks up the turtle’s Pen down() None Puts down the turtle’s Pen Functions in Turtle Module Method Parameter Description color() Color name Changes the color of the turtle’s pen fillcolor() Color name Changes the color of the turtle will use to fill a polygon heading() None Returns the current heading position() None Returns the current position goto() x,y Move the turtle to position x,y begin_fill() None Remember the starting point for a filled polygon end_fill() None Close the polygon and fill with the current fill color dot() None Leave the dot at the current position stamp() None Leaves an impression of a turtle shape at the current location shape() shapename Should be ‘arrow’, ‘classic’, ‘turtle’ or ‘circle’ SPIROGRAPHIC To use the turtle library start with import turtle.
For the background color we can use the turtle function bgcolor(). Set the background color to black.
Next we need to create the object turtle using Turtle() and store it in the variable t. SPIROGRAPHIC The colors purple and violet are used. We can define them here in a list.
We need to set the speed of the robotic turtle in order to move it with a uniform speed. The speed() function does this job. SPIROGRAPHIC We can use a for loop here and loop about 400 times with the range() function.
With the forward() function we draw a straight line. Next we need to define the angle. In one iteration of the loop we want to use purple, the next iteration violet and keep alternating like that in each iteration. SPIROGRAPHIC Finally let write turtle.done() to keep the screen open after the code is done running.
