• Item 26: Mixins
  • Good to see practice formalized
  • No __init__ was a new practice for us.  Would add cleanliness to some code.
• Item 28: collections.abc
  • Fluently pythonic objects are great.  We should do more of them.  This makes it easy.

Notes

• Coroutines: Confusing example.  What is the benefit?
  • Separates dumb client and smart server
  • Probably not the kind of thing we want to write in edX production code (probably)
• concurrent.futures
  • Allows you to send data in chunks
• When to use threads vs. concurrent.futures:
  • lower level – to implement different patterns of work.
• subprocess doesn't let you interact with the called process.  Use pyexpect ( ?)
  • subprocess creates two threads to deal with I&O, 
• LMS Grading has a five day timeout before getting hard-killed. 
  
  • This should be parallelizable.
