What You'll Learn
- Differentiate programs, processes, and threads and explain shared-state risks in multithreaded code
- Analyze concurrency vs parallelism and relate cooperative vs preemptive scheduling to system behavior
- Evaluate throughput vs latency tradeoffs and choose threading, multiprocessing, or asyncio appropriately
- Apply Python threading primitives (Lock, RLock, Condition, Semaphore, Event, Barrier, Timer) to sync work
- Implement multiprocessing patterns using start methods, IPC (queues/pipes), Pools, and Managers for sharing state
- Build asyncio solutions with generators, coroutines, futures/tasks, and event loops for non-blocking I/O
- Solve classic concurrency problems (RW lock, token bucket, philosophers, barber, queues, merge sort) in Python

About this course
WHY I WROTE THIS COURSE
Concurrency in Python is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage. This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors, Event Loops and Deferred Callbacks in depth. It also builds simple and complete solutions to popular concurrency problems that can be asked about in interviews like the Reader-Writer Problem and the Dining Philosopher Problem. While prior knowledge of concurrency is not required to follow through with this course, familiarity with the very basic Python would be helpful.
