Maze Solver: Breadth-First Pathfinding
Generate a maze, then watch breadth-first search flood it and trace the shortest way out. The graph algorithm interviewers actually ask about.
What you'll be able to build
Generate a maze, then watch breadth-first search flood it and trace the shortest way out. The graph algorithm interviewers actually ask about. Along the way you pick up real, transferable Python skills, not just this one project:
- modeling a grid/graph as nodes & edges
- the queue (collections.deque) & BFS
- visited-set tracking to avoid cycles
- reconstructing a shortest path from parents
- 2D coordinate math & neighbors
- rendering the solved path as ascii
A course like this one
Yours is built from your own placement, so module count and depth will differ. This map shows what a intermediate-level Python learner building Maze Solver actually gets.
- Module 1: Values and output5 lessons
Builds the script for your maze solver.
- Module 2: Collections and data5 lessons
Builds the data flow workflow for your maze solver.
- Module 3: Branching and state5 lessons
Builds the function that powers your maze solver.
- Module 4: Functions and tests5 lessons
Builds the reusable module for your maze solver.
- Module 5: Files, APIs, and persistence5 lessons
Builds the service boundary for your maze solver.
- Module 6: Packaging and review3 lessons
Builds the release package for your maze solver.
How the lessons actually work
Every lesson has you predict what a piece of Python code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Maze Solver, and a runnable proof page tied to your own code.
Common questions
How long does the Maze Solver: Breadth-First Pathfinding course take?
about 7 hours, across 6 modules and 28 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.
Do I need experience?
Some. This is an intermediate-tier Python project, so it assumes you're comfortable with Python basics and pushes past them.
How much does it cost?
$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.
