Use the 'TURTLE' Library in Python to realize complex graphic drawing

Using the 'TURTLE' library in Python, we can draw a variety of complex graphics, including geometric shapes, star, patterns, and so on. Python's 'TURTLE' library is a drawing library that allows us to control a turtle by programming and let it draw the graphics we want on the screen.The turtle faces the right side of the right side, can move forward and draw lines, or rotate the direction. To draw complex graphics, we need to introduce the ‘TURTLE’ library first: Import Turtle. Then create a turtle object: tur = turtle.turtle (). Next, we can use a series of commands to control the movement and drawing of turtles. For example, to draw a square, we can use the following code: import turtle # 象 tur = turtle.Turtle() # Draw a square for i in range(4): Tur.Forward (100) # Move 100 pixels forward Tur.right (90) # Right to 90 degrees # 结 结 turtle.done() The above code first creates a turtle object Tur, and then uses for cycle to execute 4 times, move 100 pixels each time, and then turn 90 degrees right, so that the turtles can complete the mission of drawing a square.Finally, the drawing is completed by calling the TURTLE.Done () method. If we want to draw other shapes, we only need to simply change the parameters of movement and rotation. In addition to the above -mentioned drawing, we can also use the 'TURTLE' Library to draw a variety of graphics, such as triangles, pentagrams, spirals, and so on. Example of drawing triangle code: import turtle # 象 tur = turtle.Turtle() # Draw triangle for i in range(3): Tur.Forward (100) # Move 100 pixels forward tur.left (120) # to 120 degrees left to 120 degrees # 结 结 turtle.done() Example of drawing pentagram: import turtle # 象 tur = turtle.Turtle() # for i in range(5): Tur.Forward (100) # Move 100 pixels forward Tur.right (144) # Right to 144 degrees # 结 结 turtle.done() Example of code -shaped code -shaped code: import turtle # 象 tur = turtle.Turtle() # for i in range(150): tur.Forward (i) # Move i pixel forward Tur.right (91) # Right to 91 degrees # 结 结 turtle.done() By using the 'TURTLE' library, we can easily implement complex graphic drawing. You only need to call the corresponding commands and parameters to complete the drawing task.At the same time, we can also create a richer and diverse graphical effect by modifying the parameters and commands in the code.
