Lesson 52 of 55
12 mins readPython Comprehensive Practice Challenges
In Plain English
Synthesize everything you have learned with hands-on practice challenges testing type system design, multiple dispatch pipelines, vectorization, and data transformations.
Deep Dive: How It Works
Problem 1: Implement an immutable CelestialBody struct and calculate gravitational attraction.
Problem 2: Build a multiple dispatch pipeline that handles polymorphic scientific units (Meters, Kilometers).
Problem 3: Implement an efficient moving average algorithm using views.
Core Rules to Remember

Multi-Concept Integration: Combine multiple dispatch, type stability, and broadcasting.

Production Julia Patterns: Idiomatic zero-allocation programming.

Micro Exercise
Implement Moving Average Filter
Define `function moving_avg(v; window=3) [sum(@views v[i:i+window-1])/window for i in 1:(length(v)-window+1)] end`.
Run `res = moving_avg([1.0, 2.0, 3.0, 4.0, 5.0])`.
Print `"Moving Avg: $res"`.
