I can only concentrate for short times at the moment and try and do only 1 hour a day. I keep this up but wished i could spend more hours on learning. How much time do you spend on learning Python?

No time at all. I already know most of the stuff I have to know, the things I don't know I learn when I need to.

I rarely "learn" Python anymore, although there are always a few "gotchas" I need to hit up the references or standard for from time to time.

Most of my time is spent writing productive code.

I spend about 2-3 hours each day... :)

I would say that I spent an hour or two a day for a couple years. Now I sit around at work for 8 hours a day forgetting it all.

Generally a couple minutes- if I forget something or need to look something up (for instance iter_swap() I looked up yesterday- and managed to corrupt my heap with it in combination with pop_back() in a vector) But I don't spend any more time learning Python itself, Other libraries on the other hand, more time than I care to mention.

14 hours a week, 2 hours a day from 10pm to midnight every night. You never stop learning Python as there is always better ways to be found on how to do things. If you think you know Python language then it is time to start learning other things like building complex software, libraries, game engines, etc. With as huge as the base is for Python you can go into any thing to learn more (socket programming, driver development, making your own SDKs, etc).

Way less time than I wish I spent.

I've stayed relatively up to date on what's been cooking with the Python11 standard, so there isn't really much more to learn in terms of language features. I can by no means recite the ISO paper by heart (nor have I read it in any detail), but most of the time now I spend on learning new idioms. Over the past month, I've dived into the boost::asio internals to see what's to learn from it.

Although, like many others here, I no longer study the syntax of Python; I have recently started running my code through OllyDbg in order to see how some of my more common operations get reduced and spit out. I can tell you that this can be some what heartbreaking to see what I thought was a function clever enough to deserve it's own header become reduced to "Why didn't you just do this JackA--?" by the compiler. And even though this is by far the most tedious and frustrating thing that has ever managed to hold my interest I feel like it's beneficial overall. So in this way I guess I spend about an hour or so each day learning new things about C\Python and Assembly. Don't do this if you are a beginner, it will ruin the hobby for you.

Just for the record, my studying was well beyond syntax--design patters and most of the Python In-Depth series books can take you to the expert level.
