Control - Z In Python Code -

-

in idle, there's no clear screen, , after reading forums best method plainly print ton of "\n"s. however, after playing idle, made discovery. when game waiting input after printing out instructions using print statements, instead of inputting useful character, entered 'control-z,' , idle began remove text display print statements, 1 one.

my main question is, how manually in code enter 'control-z', can utilize functionality?

if you're confused story, here's example code , try hitting control-z.

print("some text") print("more text") input("the input (hit control - z here):")

^z bit of mess. ascii control char ^d interpreted eot, end of transmission, on unix , many other systems means end of file, close application. ascii ^z meant interpreted sub, substitute, whatever means. editors ofter use undo (meaning undo ^x cut). microsoft (and few other old systems) @ least interprets ^z end of file, same effect ^d on *nix.

the windows console closes text app after ^z . ^d passes on app. idle, cross-platform app, closes on ^d. idle used close on ^z on windows, now, me, erases prompt. (i don't know if alternative intended.) not see progressive deletion report. os , python version running?

to answer main question: can't. input used in assignment statements: string = input('prompt'). way imitate input statements directly assign 'user input': s = 'simulated user input'. however, not work characters intercepted programs managing input window , never sent python program.

idle's shell imitates python's interactive console. latter (at least on windows) makes everything, except current input, read-only. shell follows suite. imitation strict regards executing user code. intended user code tested in idle should run in python without idle. wrong idle clear interactive shell in response user code when python cannot.

for editor , output windows, ^a (select all) followed backspace (delete), delete, or ^x (cut) clear window.

shell does, however, has more editing commands many (most? all?) consoles , menu system. these additions allowed since interactive , not accessible user code. there have been various proposals , patches enable clearing part or of shell window. https://bugs.python.org/issue6143 has of discussions , proposals.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
