Quickly get started: Use the 'TURTLE' Library in Python to draw basic geometric graphics The 'TURTLE' library in Python is a powerful graphic module that can be used to draw various geometric graphics, including lines, polygons, circles, and so on.It can draw through robots similar to turtles. Through simple orders, you can achieve various interesting graphics effects. This article will introduce how to use the 'Turtle' library in Python to draw basic geometric figures, including straight lines, polygons and circles.We will gradually explain related programming code and configuration. 1. Import the Turtle Library First of all, you need to use the TURTLE library to import it.In Python, you can use the following command to import the TURTLE library: python import turtle 2. Create a canvas Before drawing, we need to create a canvas (window) to display our graphics.You can use the following code to create a canvas: python window = turtle.Screen() 3. Create an example of a turtle Create a turtle instance to draw graphics.You can use the following code to create a turtle example: python my_turtle = turtle.Turtle() 4. Draw straight line Draw a straight line is one of the simplest operations.Using the `FORWARD ()" command allows the turtles to move forward a certain distance, that is, draw a straight line.For example, draw a straight line with a length of 100 to use the following code: python my_turtle.forward(100) 5. Draw polygon To draw a polygon, just draw a straight line repeatedly.For example, the following code can be used to draw a square: python for _ in range(4): my_turtle.forward(100) my_turtle.right(90) In the above code, we use the `for` cycle to repeat 4 times, each drawing line length is 100, and turn 90 degrees to the right to draw the next straight line. 6. Draw circular To draw circles, you can use the `city () code.Among them, the parameter represents a circular radius.For example, draw a circle with a radius of 50 to use the following code: python my_turtle.circle(50) In the above code, we use the `Circle ()" command to specify 50 radius, and turtles will draw a circular round with a radius of 50. 7. Complete the cleaning work after drawing When we complete all drawing, we can do some cleaning work to close the drawing window.You can use the following code to clean up: python turtle.done() In the above code, the `done ()` function will keep the window open until it is manually closed. This is the fast entry guide to draw basic geometric graphics in the 'TURTLE' library in Python.Through these simple code examples, you can start exploring more functions and options for the 'Turtle' library to create more exciting graphics effects.I hope you have fun!
