partially initialized module 'turtle' has no attribute 'forward' (most likely due to a circular import)

Question

My code

import turtle 
turtle.forward(15)

It shows the error : partially initialized module 'turtle' has no attribute 'forward' (most likely due to a circular import)

Answer 1

Oh yeah I savved my file by turtle.py

^{-- comment by OP}

Don't do that! Your code will not import the Python turtle.py library but rather assume your code is that library. And all the functions and methods, like forward() will be missing.

Answer 2

[Edit: I misinterpreted the problem. The answer below was given on the assumption that the turtle-library only works in an object oriented way.]

The problem with your code is that you to not create an instance of the turtle class before using is. Importing a library with "import turtle" basically only is like telling you program that a library with that name exists. To use the functionality of the imported library, you first have to generate a turtle-object (which you can also name turtle, but I'm using my_turtle to clarify the difference).

import turtle
my_turtle = turtle.Turtle
my_turtle.forward(20)

So you import the turtle library, which contains a class named Turtle, and with "my_turtle = turtle.Turtle", you create an instance of that class, which is a Turtle. Mind that you also have to set a screen on which your turtle draws, using

screen = turtle.Screen
screen.exitonclick()

Additionally, you should refer to the documentation of the turtle library. Turtle is very well documented in a way that even new programmers can easily learn the basic concepts by reading the documentation: https://docs.python.org/3/library/turtle.html
