NameError: name ‘screen’ is not defined. Did you mean: ‘Screen’?

In python NameError: name ‘screen’ is not defined. Did you mean: ‘Screen’? we face this error message when we import screen from turtle and convert screen variable [small s ]  then we need to use value Screen [Capital S ] but we use screen [small s ] then the python interpreter shows this error message, If you want to fix this error you need to just remove screen [small s ]  and type Screen [Capital S ], For more clarification, see the below example.

Wrong Code

import turtle
from turtle import Screen
screen = screen()
turtle.shape("turtle")
turtle.color("red")

# Step 2 set turtle starting position
turtle.penup()
turtle.goto(0, -100)
turtle.pendown()
turtle.pensize(5)

# Step 3 Draw a heart shape
turtle.begin_fill()
turtle.left(140)
turtle.forward(224)
turtle.circle(-112, 200)
turtle.setheading(60)
turtle.circle(-112, 200)
turtle.forward(224)
turtle.end_fill()

screen.exitonclick()
