Each Python Programming example takes a typical course question and works through it in full, so you can see what markers are looking for.
Open a topic for the full explanation, workings and any code.
You're given a list of integers `nums`, sorted in ascending order, and a value `target`. Write a function that returns the index of `target` if it's in the list and `-1` if it isn't. Your solution has to run in O(log n) time.
Build a small web API in Python with Flask and SQLite that stores `assignments` (title, subject, deadline). It must let a client list all assignments and add a new one, reply in JSON and use sensible HTTP status codes. Show how the same pattern extends to update and delete.
A dataset of student submissions has duplicate rows, subject names typed in different ways, a missing score and dates in two formats. Clean it with Pandas so it's ready for analysis, then print summary statistics.
Given the `head` node of a singly linked list, reverse the list in place and return the new head. Use O(n) time and only O(1) extra space.
