Prerequisite: Turtle Programming Basics
Turtle is an inbuilt module in Python. It provides drawing using a screen (cardboard) and turtle (pen). To draw something on the screen, we need to move the turtle (pen). To move turtle, there are some functions i.e forward(), backward(), etc.
Approach:
Following steps are used :
- Import turtle
- Set screen
- Make turtle
- Draw the y-axis lines
- Draw the x-axis lines
- Draw the x-axis and y-axis with labeling.
Below is the implementation :
Python3
# import package and making objectsimport turtlesc=turtle.Screen()trtl=turtle.Turtle()# method to draw y-axis linesdef drawy(val): # line trtl.forward(300) # set position trtl.up() trtl.setpos(val,300) trtl.down() # another line trtl.backward(300) # set position again trtl.up() trtl.setpos(val+10,0) trtl.down() # method to draw y-axis linesdef drawx(val): # line trtl.forward(300) # set position trtl.up() trtl.setpos(300,val) trtl.down() # another line trtl.backward(300) # set position again trtl.up() trtl.setpos(0,val+10) trtl.down() # method to label the graph griddef lab(): # set position trtl.penup() trtl.setpos(155,155) trtl.pendown() # write 0 trtl.write(0,font=("Verdana", 12, "bold")) # set position again trtl.penup() trtl.setpos(290,155) trtl.pendown() # write x trtl.write("x",font=("Verdana", 12, "bold")) # set position again trtl.penup() trtl.setpos(155,290) trtl.pendown() # write y trtl.write("y",font=("Verdana", 12, "bold")) # Main Section# set screensc.setup(800,800) # set turtle featurestrtl.speed(100)trtl.left(90) trtl.color('lightgreen')# y linesfor i in range(30): drawy(10*(i+1))# set position for x linestrtl.right(90)trtl.up()trtl.setpos(0,0)trtl.down()# x linesfor i in range(30): drawx(10*(i+1))# axistrtl.color('green')# set position for x axistrtl.up()trtl.setpos(0,150)trtl.down()# x-axistrtl.forward(300)# set position for y axistrtl.left(90)trtl.up()trtl.setpos(150,0)trtl.down()# y-axistrtl.forward(300)# labelinglab()# hide the turtletrtl.hideturtle() |
