i getting following error:

error: unexpected ')' in "name = "weather111")"

the problem here failed note first error noted @zero323. higher possibly not visible:

> mcweather111 <- new("markovchain", states = c("start", "1", "2","3","4","5","6", "7", "8", "9,"10", "11","12", "13", "14", "15", "16", "17","18", "19", "20", "21", "22","23","24","end"), error: unexpected numeric constant in "mcweather111 <- new("markovchain", states = c("start", "1", "2","3","4","5","6", "7", "8", "9,"10" > transitionmatrix = matrix(data = c( + 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0,

the missing double-quote visible near end of error display.

errors appear subsequent first error not "real" errors. however, if fix error, error displayed not occur, but there error thrown markovchain's error checking logic:

.... snipped of upper text... 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0), byrow = true, nrow = 26), + name = "weather111") error in validobject(.object) :    invalid class “markovchain” object: error! row sums not equal 1

that's error in data entry. need fix it:

> rowsums(transitionmatrix)  [1] 1.0 1.0 1.0 1.0 1.0 1.0 0.9 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 [20] 1.0 1.0 1.0 1.0 0.5 1.0 0.0

resizing Telegram inline keyboard -

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...
