In Python, indentation is typically done using spaces rather than the tab key. Most style guides, including PEP 8 (the Python Enhancement Proposal that describes the style guide for Python code), recommend using 4 spaces for each level of indentation.
In modern code editors and IDEs, when you press the “Tab” key, it often inserts spaces instead of an actual tab character by default.
So try using the space key and give 4 spaces for each level of indentation.
Thank you. I am taking “JavaScript Algorithms and Data Structures (Beta)”. I’m not sure if you have a specific accessibility feature set in your browser, but I don’t remember changing it.
FYI, you can control whether the Tab key inserts a tab or moves you to the Check Your Code button using the Ctrl+m toggle. While your keyboard focus is in the editor, press Ctrl+m to toggle between these two options. Inserting tabs is the default, so perhaps you accidentally hit Ctrl+m and turned that off by mistake?
