Python Classroom notes 22/Aug/2026

Threads, Thread pool, Concurrency and Async

• CPU Intensive activities use multiprocessing
• IO intensive activities: (async)
  • Calls are blocked

Lets create a simple python module which demonstrates the async

• We are supposed to download files from internet
  • we have a python function
    python
def download_file(url:str):
pass
• When we are downloding multiple files (blocking style)

for url in urls:
    download_file(url)

Async await and loop

• Refer Here for async

• Refer Here for examples
