Thonny has a bunch of other great features to help you write more accurate code more quickly. Thonny highlights lines with syntax errors so you can find them more easily. You can also View the Assistant to see what the problem is more detail.
Thonny can highlight the names of variables. Because it knows about variable scope, it can tell the difference between local and global variables. This feature isn’t turned on by default, but you can opt into it.
Thonny can also perform code completion. This is handy because it can let you know what’s available from a module that you’ve imported. It can also help you avoid typos and reduce the amount of time it takes to type.
Thonny’s package manager is also useful. Packages are one of Python’s greatest strengths. They are downloadable modules that allow you to extend Python’s functionality and create programs without having to reinvent the wheel.
