+**Turtle Graphics**

+#import turtle defines the module turtle which will allow you to create a Turtle object and draw with it.

+**Using properties**
+
+```
+import turtle 
+scrn = turtle.Screen()
+scrn.bgcolor("lavender")
+#the object scrn has color property(which we write as bgcolor)
+arin = turtle.Turtle()
+arin.color("blue")
+arin.pensize(3)
+#the object arin has property/attribute - color,pensize
+arin.forward(100)
+arin.right(90)                    #name.right(90) goes downward

+arin.pensize(4)
+arina.forward(100)
+arina.left(90)                    #name.left(90) goes upward
+arina.forward(90)
+
+#name.right(value)/name.left(value) works for defining angles(degrees).
