Answer : I created a board of labels and color them according to which is clicked: import Tkinter as tk board = [ [None]*10 for _ in range(10) ] counter = 0 root = tk.Tk() def on_click(i,j,event): global counter color = "red" if counter%2 else "black" event.widget.config(bg=color) board[i][j] = color counter += 1 for i,row in enumerate(board): for j,column in enumerate(row): L = tk.Label(root,text=' ',bg='grey') L.grid(row=i,column=j) L.bind('<Button-1>',lambda e,i=i,j=j: on_click(i,j,e)) root.mainloop() This doesn't do any validation (to make sure that the element clicked is at the bottom for example). It would also be much better with classes instead of global data, but that's an exercise for the interested coder :). You probably want to create a grid of Buttons. You can style them according to the values in board , and assign a callback that updates the board when clicke

Answer : The only short circuiting (of a sort) is within Case expression evaluation, so the following ungainly statement does what I think you're asking; Select Case True Case (myObject Is Nothing), Not myObject.test() MsgBox "no instance or test == false" Case Else MsgBox "got instance & test == true" End Select End Sub This is an old question, but this issue is still alive and well. One workaround I've used: Dim success As Boolean ' False by default. If myObj Is Nothing Then ' Object is nothing, success = False already, do nothing. ElseIf Not myObj.test() Then ' Test failed, success = False already, do nothing. Else: success = True ' Object is not nothing and test passed. End If If success Then ' Do stuff... Else ' Do other stuff... End If This basically inverts the logic in the original question, but you get the same result. I think it's a cleaner solution t

Answer : All Kotlin functions declared in a file will be compiled by default to static methods in a class within the same package and with a name derived from the Kotlin source file (First letter capitalized and ".kt" extension replaced with the "Kt" suffix). Methods generated for extension functions will have an additional first parameter with the extension function receiver type. Applying it to the original question, Java compiler will see Kotlin source file with the name example.kt package com.test.extensions public fun MyModel.bar(): Int { /* actual code */ } as if the following Java class was declared package com.test.extensions class ExampleKt { public static int bar(MyModel receiver) { /* actual code */ } } As nothing happens with the extended class from the Java point of view, you can't just use dot-syntax to access such methods. But they are still callable as normal Java static methods: import com.test.extensions.ExampleKt; MyMod

Answer : Here's a quick and dirty way to get what you want. Background WordPress stores admin menu sections in a global array called $menu . To add a separator you add an element to the $menu array using an index that is between the indexes of the options that you want to separate. Using the add_admin_menu_separator() function So I've written a function to encapsulate the logic for this I called add_admin_menu_separator() . You'll need to pick an array index number that is higher than the option after which you want to add a separator, and then call the function add_admin_menu_separator() passing said index as your parameter. For example: add_admin_menu_separator(37); The add_admin_menu_separator() function itself Here's the definition of the function add_admin_menu_separator() which you can copy into your theme's functions.php file. Yes it is arcane but then so is the code that creates and uses the global $menu array. (Plans are to eventu

Example 1: continue python The continue statement in Python returns the control to the beginning of the while loop . The continue statement rejects all the remaining statements in the current iteration of the loop and moves the control back to the top of the loop . The continue statement can be used in both while and for loops . Example 2: python continue for i in range ( 10 ) : if i == 3 : # skips if i is 3 continue print ( i ) Example 3: continue statement python import numpy as np values = np . arange ( 0 , 10 ) for value in values : if value == 3 : continue elif value == 8 : print ( 'Eight value' ) elif value == 9 : break Example 4: python for continue >>> for num in range ( 2 , 10 ) : . . . if num % 2 == 0 : . . . print ( "Found an even number" , num ) . . . continue . . . print ( "Found a number" , num ) Found an even number 2 Found a number 3 Found an

Answer : You can have multiple files in the .github/workflows folder. All files will be read and run as independent tests. The 'on' parameter on each file will tell when it must be called. Following your idea you could have: dev.workflow.yml - To run some kind of testing maybe (only on dev branch, when push) name: Dev Workflow - Test and check thing on: push: branches: - dev jobs: ... prod.workflow.yml - To build and deploy your project (only on master branch, when a PR is closed) name: Master Workflow - Build and deploy to production on: pull_request: types: closed branches: - master jobs: ... Since this question was asked, GitHub has made a few changes to workflows. They are now written in YAML syntax rather than HCL, and instead of being stored in a .github/main.workflow file, they are stored in a .github/workflows directory. The documentation says that "You must store workflow files" (note the plural) "in the .gith

Example: compilation vs runtime error in c A runtime error happens during the running of the program. A compiler error happens when you try to compile the code. If you are unable to compile your code, that is a compiler error. If you compile and run your code, but then it fails during execution, that is runtime.

Answer : IE11 uses an older version of the Grid specification. The properties you are using don't exist in the older grid spec. Using prefixes makes no difference. Here are three problems I see right off the bat. repeat() The repeat() function doesn't exist in the older spec, so it isn't supported by IE11. You need to use the correct syntax, which is covered in another answer to this post, or declare all row and column lengths. Instead of: .grid { display: -ms-grid; display: grid; -ms-grid-columns: repeat( 4, 1fr ); grid-template-columns: repeat( 4, 1fr ); -ms-grid-rows: repeat( 4, 270px ); grid-template-rows: repeat( 4, 270px ); grid-gap: 30px; } Use: .grid { display: -ms-grid; display: grid; -ms-grid-columns: 1fr 1fr 1fr 1fr; /* adjusted */ grid-template-columns: repeat( 4, 1fr ); -ms-grid-rows: 270px 270px 270px 270px; /* adjusted */ grid-template-rows: repeat( 4, 270px ); grid-gap: 30px; } Older spec re

Answer : Telegram is a popular messaging application. This library is meant to make it easy for you to write Python programs that can interact with Telegram. Think of it as a wrapper that has already done the heavy job for you, so you can focus on developing an application. If you are the owner of the Telegram channel/group, you can use BotFather to create a bot. However, if you are not the admin of the channel/group, you can use Telethon to create Telegram bot Telethon is an asyncio Python 3 MTProto library to interact with Telegram's API as a user or through a bot account (bot API alternative). Install Telethon # The first thing is install Telethon pip install telethon Create Application # Before working with Telegram’s API, you need to get your own API ID and hash: Login to your Telegram account with

Answer : I faced the same problem in my network. When you use this command: ping icecream It uses WINS server since you have used icecream not icecream.my.domain . When looking for such words, Windows looks for NETBIOS names, but when you look for complete domain records, it will look in the DNS server. You can use one of the solutions below: Make sure you have correct records for that station in your WINS server. Use the complete domain name instead of using the host file. E.g. icecream.my.domain You don't have DNS suffixes configured. Either configure them, or use FQDN like this and it should work: ping icecream.my.domain

Answer : sequence from 18.04 to 20.04 sudo apt update sudo apt upgrade sudo apt dist-upgrade sudo apt autoremove sudo do-release-upgrade -d -f DistUpgradeViewGtk3 Follow onscreen instruction. Good luck! I was also experiencing the same issue. However, when I ran the usual upgrade commands ( sudo apt upgrade , sudo apt full-upgrade , sudo apt-get dist-upgrade ), they were all reporting that there are no packages to upgrade and no held packages : 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. In the end, I copied the file /usr/bin/do-release-upgrade to my home and modified it as follows: for pkg in upgradable: if 'Phased-Update-Percentage' in pkg.candidate.record: # P-U-P does not exist if it is fully phased continue else: install_count += 1 print(pkg) # <--- ADD THIS LINE # one upgradeable package is enough to stop the dist-upgrade # break # <--- COMMENT THIS LINE OUT This change will print the names of all

Answer : I use File -> Switch Workspace -> Other... and type in my new workspace name. (EDIT: Added the composite screen shot.) Once in the new workspace, File -> Import... and under General choose "Existing Projects into Workspace. Press the Next button and then Browse for the old projects you would like to import. Check "Copy projects into workspace" to make a copy. In Window->Preferences->General->Startup and Shutdown->Workspaces , make sure that 'Prompt for Workspace on startup' is checked. Then close eclipse and reopen. Then you'll be prompted for a workspace to open. You can create a new workspace from that dialogue. Or File->Switch Workspace->Other... You can create multiple workspaces in Eclipse. You have to just specify the path of the workspace during Eclipse startup. You can even switch workspaces via File→Switch workspace. You can then import project to your workspace, copy paste project to your new workspace folder

Answer : No. Those files are gone. (Just checked on Linux: git clean calls unlink() , and does not backup up anything beforehand.) git clean -fdxn Will do a dry run, and show you what files would be deleted if you ran git clean -fdx (of course this is only helpful if you know this ahead of time, but for next time) IntelliJ/Android Studio allows restoring files from local history.

Answer : According to the CSS basic box model, an element's width and height are applied to its content box. Padding falls outside of that content box and increases the element's overall size. As a result, if you set an element with padding to 100% width, its padding will make it wider than 100% of its containing element. In your context, inputs become wider than their parent. You can change the way the box model treats padding and width. Set the box-sizing CSS property to border-box to prevent padding from affecting an element's width or height: border-box : The width and height properties include the padding and border, but not the margin... Note that padding and border will be inside of the box. Note the browser compatibility of box-sizing (IE8+). At the time of this edit, no prefixes are necessary. Paul Irish and Chris Coyier recommend the "inherited" usage below: html { box-sizing: border-box; } *, *:before, *:after { box-sizing: inherit; } For ref
