问题 Is there a way to have Sass print out a variable to the terminal? 回答1: Sass 3.3 and older There are 2 error related directives: @debug The @debug directive prints the value of a SassScript expression to the standard error output stream. @debug 10em + 12em; outputs: Line 1 DEBUG: 22em @warn The @warn directive prints the value of a SassScript expression to the standard error output stream.

For example, if the user entered X:0 and Y:0 it would change the value '9' in the image below to a predefined value (in this case I want to change the value 9 to 0). My question is, is it possible to update the output of the console so that the '0' would override the '9' without printing out the entire grid again. I want to be able to do this multiple times. If that is not possible, how

问题 I have a simple Python script which uses selenium and webdriver to open up Facebook in a Chrome window and log in automatically. When I run it, the Chromedriver console window opens up and stays open even after the entire program has finished execution, until I close it myself. Is there a way to hide this console window? I have tried keeping a ".pyw" extension for my script, but that doesn't help since it's not the script's console window but the Chromedriver subprocess' console window that I
