python - Convert Procedural to Object Oriented: Python3.4 -


in interest of being more "pythonic" (and being more modular), want convert procedural code class. object of interest here idea of marriage of husband , wife, referred here lastname, shared , unique attributes among each spouse. these attributes being filled in file generator object via yield.

part of me wants perform these 2 parsing functions get_husband , get_wife (and maybe final zip function) class function still uses iterator object fill in attributes of marriage.firstname, marriage.husbandscore, marriage.wifescore, etc. create methods perform further analysis on information each marriage object spit out generator.

but part of me unsure whether parsing definitions best kept methods, since returning self not generator need downstream work...

from itertools import izip  def get_husband(husbandfile):     lastname, firstname, husbandscore = '', '', ''     line in husbandfile.readlines():         # parse files fill out names, wifescores in wifefile         yield name, husbandscore  def get_wife(wifefile):     lastname, firstname, wifescore = '', '',''     line in wifefile.readlines():         # parse files fill out names, wifescores in wifefile         yield name, wifescore  def make_family(husbandfile, wifefile):     husband, wife in izip(get_husband(husbandfile), get_wife(wifefile)):         if husband[0] == wife[0]:             lastname = husband[0]             parentscore = husband[1] + wife[0]              yield lastname, parentscore         else:             raise exception("these 2 aren't married

what suppose best way factor class can like: min_score = marriage.parentscore.min()

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
