How to remove variable from last iteration of while loop in python -

-
im not expert @ python , ive got following while loop. padding iterations buffer. however, results in unwanted padding in last iteration of while loop. there way can remove this? # send data packets. bytes_sent = 0 while (bytes_sent < len(padded_buf)): bytes_to_send = len(padded_buf) - bytes_sent assert bytes_to_send % 4 == 0 bytes_this_block = min(_max_block_size, bytes_to_send) s.send(padded_buf[bytes_sent:(bytes_sent + bytes_this_block)]) bytes_sent += bytes_this_block # clean , return. s.close() return bytes_sent cheers helps. i'm not sure you're trying remove… whatever is, can easily. if want remove after fact, can. of variables define inside while loop still available after done, value last iteration. can this: padded_buf = padded_buf[:-bytes_this_block] but really, better not add in first place. put if statement in middle of while , break if you've reached end.

python - Route testing with Tornado -

-
i'm new tornado, , working on project involves rather complex routing. in of other frameworks i've used i've been able isolate routing testing, without spinning server or doing terribly complex. i'd prefer use pytest testing framework, i'm not sure matters. is there way to, say, create project's instance of tornado.web.application , , pass arbitrary paths , assert requesthandler invoked based on path? no, not possible test in tornado via public interface (as of tornado version 4.3). it's straightforward avoid spinning server, although requires nontrivial amount of code: interface between httpserver , application well-defined , documented. trickier part other side: there no supported way determine handler invoked before handler is invoked. i recommend testing routing via end-to-end tests reason. store url route list before passing tornado, , tests against - internal logic of "take first regex match" pretty easy replicate.
