python - Sympy fails to find Fourier Transform of Complex Hyperbolic Secant (Sech) Function -


i'm trying use sympy find fourier transform of hyperbolic secant function ("sech") complex argument.

import sympy sy c, t, t0, f, w = sy.symbols('c, t, t_0, f, omega', real=true) ut = sy.sech(t/t0) * sy.exp(-sy.sqrt(-1) * c / 2 * t * t / (t0 * t0)) uf = sy.fourier_transform(ut, t, f)

unfortunately, sympy seems hang when request this.

is bug or there better way present request sympy?

thanks

it's bug, unfortunately. sympy cannot handle integral, , gets stuck in integration algorithm.

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
