we can import modules using the module name and import keyword
we can import the full module or specific functions in that module
if there is any reference warning right click on the function and choose ignore
unresolved references

# turtle.forward(400)
# turtle.circle(250)

# #the done function is used to hold the screen to see the result
# #or else we can use the time module and sleep function
#
#
# for i in range(0,100,10):
# turtle.forward(i)
# turtle.circle(i)
# turtle.right(i)
#
#
# turtle.done()
#if we need only the particular functions we can code like below
# from turtle import circle,done
#
# circle(70)
# done()
#or else we can do use *
# from turtle import *
#
# circle(70)
# done()
#we will get the error if we run the below piece of code
#since the done is common here,we declared as string,but the turtle method
#also has the "done" as function
