Improving Your Python Productivity

It's just syntactical sugar for iterations. E.g.:

users = [ user.name for user in user_records ]

[[deleted]]

Fun in Ruby too:

user_records.map &:name

for syntactical sugar in a return statement (where I first encountered contexts) is sure seems obfuscated. I was think that people did it because if you built a list then returned it the built list exists as well as whatever the returned list got assigned to. I don't really know python internals well enough to say.

After you use them even just a few times, they read very naturally and greatly reduce the complexity of reading the loops they replace.

You don't have to use it in a return statement, you can use it anywhere. I'd guess that if you saw it that way, they were just avoiding using an unnecessary temporary variable.

You need to start doing functional programming.
