Title of the talk

Mental Model of Concurrency in the Python World from a Beginner's Perspective

Description

'Building a Mental Model of Concurrency in Python.' In this talk, aimed at those new to the world of programming, we'll explore the fundamentals of concurrency, Python's concurrency models (including Gevent and asyncio), and how they enable multiple tasks to run simultaneously. We'll also delve into Gevent's efficient approach, its use of shared stacks, and how it reduces context-switching overhead. Whether you're a complete beginner or looking to enhance your understanding of Python's concurrency, this talk will provide you with valuable insights into the world of concurrent programming

Table of contents

Introduction (2 minutes)

• Explain the importance of understanding concurrency in programming.

Section 2: Python's Concurrency Models (4 minutes)

• Introduce Python's concurrency models:
  • Threading
  • Multiprocessing
  • Gevent
  • Asynchronous programming (async/await)

Section 3: Building Intuition for Further Talk (4 minutes)

• Explore the theoretical aspects of concurrency in Python, including the concept of multithreading, the role of event loops in managing asynchronous operations, and how coroutines, built upon generators, form a fundamental building block of asynchronous programming.

Section 4: Gevent's Efficient Concurrency Model (4 minutes)

• Elaborate on Gevent's approach to concurrency. How it uses the same stack to perform concurrent operations and avoids the overhead of context switches. Explain the concept of green threads, which are lightweight, user-space threads that Gevent employs.

Section 5: Asynchronous Programming with Asyncio (4 minutes)

• Introduce asyncio, Python's built-in asynchronous programming library.
• Explain the concept of asynchronous programming using async/await.

Section 6: Building a Mental Model (2 minutes)

• Highlight that Gevent and asyncio are two options, with Gevent focusing on coroutines and shared stacks, and asyncio using async/await for asynchronous I/O.
• Encourage beginners to explore concurrency in Python further.
• Provide references for continued learning.

Conclusion (1 minute)

• Summarize the key takeaways of the talk.
• Reiterate the importance of understanding concurrency in Python.
