Could not find a version that satisfies the requirement turtule (from versions: none)

The error message you are seeing indicates that the package "turtule" is not available in any version compatible with your current environment. This is likely due to a typo in the package name: the correct package name is "turtle" (without the extra "u"). To install it, you can use pip, the Python package installer, by running the following command in your terminal:

pip install turtle

This should install the "turtle" package and allow you to use it in your Python code.
