Creative programming practice: art paintings through the 'TURTLE' Library in Python

Creative programming practice: art paintings through the 'TURTLE' Library in Python introduce: ‘Turtle’ is a module in the Python standard library that provides a function of drawing graphics.It simulates a turtle and uses simple commands to move and draw graphics.By using the 'TURTLE' library, we can achieve various painting effects and create vivid and interesting art works. Programming code and configuration: First, we need to import the ‘Turtle’ library: python import turtle Then, we can perform some basic configurations, such as setting the background color and boundary of the canvas: python turtle.setup(800, 600) turtle.bgcolor("white") turtle.screensize(780, 580) Next, we can create a brush and perform some basic configurations, such as setting the color and speed of the brush: the color and speed of the brush: python pen = turtle.Turtle() pen.color("black") pen.speed(5) With the above preparation, we can start painting.Here are some common 'TURTLE' commands: -Pending: `Pen.Forward (distance)`, where the `distance` is a distance of forward. -The back: `Pen.backward (distance)`, where the `distance` is a distance of backward. -The left: `Pen.left (angle)`, where `Angle` is the angle of the left turn. -The right turn: `Pen.right (Angle)`, where `Angle` is the angle of the right turn. -Dipping: `Pen.circle (Radius)`, where `Radius` is the radius of the circle. -Lore up the pen tip: `Pen.up ()`, make the pen tip lift, leave no traces when moving. -Reamed the pen tip: `Pen.down ()`, let the pen tip down, leave traces when moving. In addition, there are other commands and configurations to use, which can be expanded according to specific needs. The following is a simple example of painting, drawing a pentagram: python pen.begin_fill() for _ in range(5): pen.forward(100) pen.right(144) pen.end_fill() In the above code, we use a cycle to draw five straight segments to achieve the effect of five -pointed star.`Begin_fill ()` and `End_fill ()` `` use it to set the colors of the filling, so that the five -pointed star is filled. Finally, we can use `turtle.done ()` command to keep the drawing window display to observe our artistic works: python turtle.done() In this way, we can use the 'TURTLE' library for art painting in Python to create unique art works.You can try different commands and configurations to draw different styles of graphics to give play to your creativity.Enjoy the fun of artistic creation brought by programming!
