Is this code allowed?

Courses often use a restricted subset of a programming language and its library, to reduce cognitive load, focus on concepts, simplify marking, detect use of copied code, etc.

allowed is a program that checks if code files (and Jupyter notebooks) only use the Python constructs that were taught.

allowed enables teachers to check in advance their examples, exercises and assessment for inadvertent use of constructs that weren’t taught. It also allows students and teachers to check submitted code against the taught constructs.

To do its job, allowed requires a short file that lists which constructs were introduced in which ‘unit’ of the course. That file can be used as a reference document to onboard new teachers and to discuss the design of the course, e.g. to check if important constructs are missing or if some units are overloaded.

• To install the tool, enter pip install allowed in a terminal
• To get a summary of the options, enter allowed -h
• To check a file with the default configuration, enter allowed yourfile.py
• To check a homework submission against the constructs taught up to unit 5, enter 
• allowed -u 5 yourfile.py
