问题 So I'm trying to make in Ruby so that it "Idk how to express myself" parse JSON from this API so the output is: {"infected"=>19334, "deceased"=>429, "recovered"=>14047, "tested"=>515395, "tested24hours"=>8393, "infected24hours"=>351, "deceased24hours"=>11, "sourceUrl"=>"https://covid19.rs/homepage-english/", "lastUpdatedAtApify"=>"2020-07-15T14:00:00.000Z", "readMe"=>"https://apify.com/krakorj/covid-serbia"} and I would like it to only show for example "infected"=>19334, as number 19334 I'm

问题 I've been trying to turn the output of the following two commands into variables, so that I can use them in a batch file, however I'm not having any luck: WMIC /namespace:\\root\SecurityCenter2 PATH AntiVirusProduct WHERE (displayName="Emsisoft Anti-Malware" or displayName="Emsisoft Internet Security") GET displayName /value WMIC /namespace:\\root\SecurityCenter2 PATH AntiVirusProduct WHERE (displayName="Emsisoft Anti-Malware" or displayName="Emsisoft Internet Security") GET

问题 I'm trying to get output in decimal form. Please tell me what I can do to get the same variable in decimal instead of ASCII. .model small .stack 100h .data msg_1 db 'Number Is = $' var_1 db 12 .code add_1 proc mov ax, @data mov ds, ax mov ah, 09 lea dx, msg_1 int 21h mov ah, 02 mov dl, var_1 int 21h mov ah, 4ch int 21h add_1 endp end add_1 回答1: These 3 lines that you wrote: mov ah, 02 mov dl, var_1 int 21h print the character represented by the ASCII code held in your var_1 variable. To print

问题 So how can I ask the user to provide me with an input file and an output file? I want the content inside the input file provided by the user to print into the output file the user provided. In this case, the user would put in this Enter the input file name: copyFrom.txt Enter the output file name: copyTo.txt inside the input file is just the text "hello world" . Thanks. Please keep it as simple as you can if possible 回答1: If you just want to copy the file, shutil’s copy file does the loop

问题 I have following code to read and redict the output of gawk to a textfile (instead of doing this with shell-execute and using > ): var processStartInfo = new ProcessStartInfo { FileName = "gawk.exe", Arguments = $@"-F ""{separator}"" -f ""{scriptFullFileName}"" ""{inputFullFileName}""", UseShellExecute = false, WorkingDirectory = workingDirectory, RedirectStandardOutput = true, CreateNoWindow = true }; using (var process = Process.Start(processStartInfo)) { using (var streamReader = process

问题 I have a shiny app and my server function looks like this: shinyServer(function(input, output, session) { filedata <- reactive({ infile <- input$file1 if (is.null(infile)) { return(NULL) } myDF <- fread(infile$datapath) return(myDF) # Return the requested graph graphInput <- reactive({ switch(input$graph, "Plot1" = plot1, "Plot2" = plot2) }) output$selected_graph <- renderPlot({ paste(input$graph) }) output$plot1 <- renderPlot({ #fill in code to create a plot1 }) output$plot2 <- renderPlot({

问题 How is the threshold for scientific notation set in an ipython notebook? I want to set all number outisde of something like [0.01, 100] to be printed in scientific notation, but the threshold seems to be much higher. i.e. In [165]: x = sympy.Symbol('x'); 1.e8*x Out[165]: 100000000.0*x but In [166]: 1.e28*x Out[166]: 1.0e+28*x Because I'm using sympy, I can't send the number to a formatted print statement, i.e. In [167]: print "%.2e" % (1.e8*x) ERROR: TypeError: float argument required, not

问题 Suppose I have a function that gives out unknown number of output arguments (it depends on input,thus change through the loops). How to get all of them? nargout doesn't help as the function uses varargout (the result is -1) And of course I can't rewrite the function, otherwise the question wouldn't arise :- ) 回答1: Well, thanks to all partisipated in discussion. Summing up, it seems the problem has no general solution, because MatLab itself estimates the number of desired outputs before the

问题 I want to read lines from a .txt file (in this case input.txt) and write them in two other .txt files depending on whether the integer number at the start of each line is odd or even. I have to use DataInputStream / DataOutputStream and BufferedInputStream / BufferedOutputStream. The input file looks like this. 1 String1 1.1 2 String2 2.2 3 String3 3.3 4 String4 4.4 5 String5 5.5 6 String6 6.6 7 String7 7.7 8 String8 8.8 9 String9 9.9 10 String10 10.1 When I run the program I get an
