How to make Triangle in Python Turtle using onscreenclick?

Turtle” is a Python feature like a drawing board, which lets us command a turtle to draw all over it! We can use functions like turtle.forward(…) and turtle.right(…) which can move the turtle around. Turtle is also Known as Logo Programming language which commands for movement and drawing produced line or vector graphics, either on screen or with a small robot termed a turtle.

Functions used

  • Turtle(): This Method is used to make object.
  • onscreenclick(functionname,1):  This turtle function which sends the current coordinate to function which further utilise to form triangle, 1 is for left click and 3 is for Right click
  • speed(): This is used to increse or decrease the speed of turtle pointer.
  • listen(): This allows the server to listen to incoming connections.
  • done(): This is used to hold the the screen.  
  • penup(): This is built in function in turtle library to draw out the line.
  • pendown(): This is built in function in turtle library to draw in the line.
  • forward(): This is built in function in turtle library to move turtle forward direction.it takes pixel unit as an argument
  • left(): This is built in function in turtle library to turn turtle left direction.it takes angle in degree as an argument

    # it is used to draw out the pen
    tess.penup()
      
    # it is used to move curson at x 
    # and y position
    tess.goto(x,y)
      
    # it is used to draw in the pen
    tess.pendown()
    for i in range(3):
        
          # move cursor 100 unit 
        # digit forward
        tess.forward(100)
          
        # turn cursor 120 degree left
        tess.left(120)
          
        # Again,move cursor 100 unit 
        # digit forward
        tess.forward(100)
          
# special built in function to send current 
# position of cursor to traingle
turtle.onscreenclick(triangle,1)
  
turtle.listen()
  
# hold the screen 
turtle.done()
