An in-depth look at generators

Generators have been evolving in Python over quite a long time:

  • Generators added in Python 2.2 (PEP 255)
  • Generator Expressions added in Python 2.4 (PEP 289)
  • Enhanced Generators added in Python 2.5 (PEP 342)
  • "yield from" added in Python 3.3 (PEP 380)

They have grown from a simple concept for lazily generating a (perhaps infinite) series of data values into a coroutine capability through the last two additions above.

Bruce will do an in-depth look at generators: the good, the bad, and the ugly...

    Bruce's presentation was very thorough. He used the ipython Notebooks webserver to present the material, which was a perfect followup to Daniel Dye's presentation of this technology.

    Generators seem to be the python equivalent of Java's java.util.Enumeration interface. Also learned the 'yield' statement. Thanks Bruce!

    Was super informative. I feel a lot more comfortable with generators, iterators, and for loops.
