问题 I am trying to send some text to a printer. I need just the text printed, wrapped at the page margin and flowing to another page if necessary. Here is a minimal example of what I am doing now: @FXML private void print() { TextArea printArea = new TextArea(textArea.getText()); printArea.setWrapText(true); printArea.getChildrenUnmodifiable().forEach(node -> node.setStyle("-fx-background-color: transparent")); printArea.setStyle("-fx-background-color: transparent"); PrinterJob printerJob =

问题 I am using the following code to try to print a variable to file. my $filename = "test/test.csv"; open FILE, "<$filename"; my $xml = get "http://someurl.com"; print $xml; print FILE $xml; close FILE; So print $xml prints the correct output to the screen. But print FILE $xml doesn't do anything. Why does the printing to file line not work? Perl seems to often have these things that just don't work... For the print to file line to work, is it necessary that the file already exists? 回答1: The <

问题 I have a program which deals with nested data structures where the underlying type usually ends up being a decimal. e.g. x={'a':[1.05600000001,2.34581736481,[1.1111111112,9.999990111111]],...} Is there a simple pythonic way to print such a variable but rounding all floats to (say) 3dp and not assuming a particular configuration of lists and dictionaries? e.g. {'a':[1.056,2.346,[1.111,10.000],...} I'm thinking something like pformat(x,round=3) or maybe pformat(x,conversions={'float':lambda x:

问题 Let's say I write a for loop that will output all the numbers 1 to x: x=4 for number in xrange(1,x+1): print number, #Output: 1 2 3 4 Now, putting that same for loop into a function: def counter(x): for number in xrange(1,x+1): return number print counter(4) #Output: 1 Why do I only obtain one value when I put the for-loop into a function? I have been evading this problem by appending all the results of the for-loop to a list, and then returning the list. Why does the for loop append all the
