python - Getting and calculating stuff through tkinter widets -


i wondering how calculate stuff using tkinter buttons. i'm making simple program calculate seconds hours:minutes:seconds. user inputs integer using entry widget on seconds box , when press calculate, result via converted time line. i'm confused on how start calculating it. know integer via .get, i'm stuck on how , calculate in h:m:s format. code far.

import tkinter tkinter import *     class timeconverterui():       def __init__(self):          self.root_window = tk()         self.root_window.geometry('400x150')         self.root_window.title('seconds converter')         self.text()         self.calculate_button()         self.quit_button()         self.root_window.wait_window()       def text(self):          row_label = tkinter.label(               master = self.root_window, text = 'seconds: ')          row_label.grid( row = 0, column = 0, columnspan=2, padx=10, pady=10,                            sticky = tkinter.w)          secondsentry = entry(master = self.root_window)         secondsentry.grid(row = 0, column = 1)          row_label = tkinter.label(               master = self.root_window, text = 'converted time(h:m:s): ').grid(row=1)      def calculate_button(self):          quit = button(self.root_window, text = "calculate", command = self.calculate)         quit.grid(row = 3, column = 0, columnspan = 3, pady=20,                   sticky = tkinter.w)      def calculate(self):          pass      def quit_button(self):          quit = button(self.root_window, text = "quit", command = self.quit)         quit.grid(row = 3, column = 3, columnspan = 3, pady=20,                   sticky = tkinter.e)      def quit(self) -> bool:          self.root_window.destroy()         return true      if __name__ == '__main__':      convert=timeconverterui()

first break code below 2 lines if ever want use row_label later because return nonetype. should define first use .grid on (just button).

row_label = tkinter.label(               master = self.root_window, text = 'converted time(h:m:s): ').grid(row=1)

now can create label show result. remember put self. before name can use in calculate function. change secondsentry self.secondsentry same reason.
now use int(self.secondsentry.get()) in function , required calculations.
set result result label .configure(text=str(result))

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...

angular - DownloadURL return null in below code -

when change file updated in firebase storage when try downloadurl show null. filechange(event: any) { const imagefolder: string = this.employee.id; const filelist: filelist = event.target.files; const file: file = filelist[0]; const storageref = firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file); console.log(storageref.snapshot.downloadurl); } the put() asynchronous. if want url after file uploaded have this: firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file).then((snapshot) => { storageref = snapshot.downloadurl: console.log(snapshot.downloadurl); });

during login process of laravel spark need request token of remote api. api stores exact same users , passwords laravel spark application. therefore need username , non hashed password of user during authentication process. i thought overriding authenticated method solution problem. in routes/web.php override post /login endpoint , pointing endpoint own logincontroller: <?php namespace app\http\controllers\auth; use illuminate\support\facades\log; use illuminate\http\request; use laravel\spark\http\controllers\auth\logincontroller sparklogincontroller; class logincontroller extends sparklogincontroller { /** * create new login controller instance. * * @return void */ public function __construct() { parent::__construct(); } /** * handle successful authentication attempt. * * @param request $request * @param \illuminate\contracts\auth\authenticatable $user * @return response */ public fu...
