I'm a student and my university uses Moodle as their learning management system (LMS). They don't have Moodle Web Services enabled and won't be enabling it anytime soon, at least for students. The university programs have the following structure, for example:
1. Bachelor's Degree in Computer Science (duration: 8 semesters) 1.1. Unit 01: Mathematics Fundamental (duration: 1 semester) 1.1.1. Algebra I (first 3 months) 1.1.2. Algebra II (first 3 months) 1.1.3. Calculus I (last 3 months) 1.1.4. Calculus II (last 3 months) 1.1.5. Unit Project (throughout the semester) 1.2. Unit 02: Programming (duration: 1 semester) 1.2.1. Programming Logic (first 3 months) 1.2.2. Data Modelling with UML (first 3 months) 1.2.3. Python I (last 3 months) 1.2.4. Python II (last 3 months) 1.2.5. Unit Project (throughout the semester) Each course/project have a bunch of assignments + one final assignment. This goes on, totalizing 8 (eight) units, which will make up for a 4-year program. I'm building my own client-side Moodle API to be consumed by my scripts. Currently I'm using 'requests' + 'bs4' to do the job.

How can I change the logic so it just gets the data I need at a given moment? For example, I may need to dump data for an entire unit, or just one course, or maybe even just one assignment. How can I achieve this behavior? Another "issue", I feel like handing my 'session' that I instantiated at user.py to program, then unit, then course and then assignment is a poor design, how can I make it better? Any other suggestions are welcome. -- https://mail.python.org/mailman/listinfo/python-list
