问题 Heys, I recently couldnt figure out how to blit lists onto my pygame screen using certain x and y values, allowing the text to blit say x += 20, moving every other string in my list over 20 units everytime it blits. I recently did some .format stuff with printing just in the console, is there a feature like this for screen.blit so I can use the same formatting in a pygame window? Included my code underneath. Thanks in advance :D import pygame NAMES = ['Deanerys T.', 'Jon S.', 'Gregor C.',

问题 I have searched for days and found one example [here][1] [1]: XSLT formatting numbers, insert '-' after every 4 digits starting from the right most digit, but it doesn't seem to work out as expected. Here is what I need to happen. I have a number that is 7 digits like '1122334' and I need to coerce it to '11-22-33-4'.

问题 I have a specific example below, which works perfectly fine if integers are inputted (see output1), when I try to scan a char using %d specifier in scanf function call I get the output2 below. So, my question is if input a char I hope the type specifier should convert it to an equivalent int value, if not a junk value, even in the either case it should print/segfault. But, here I'm getting continuous prints which I feel is wrong as scanf is getting bypassed every single time. I'm pretty

问题 (First of all: this is not a duplicate of Format numbers with floating points and sign in textbox in C#) I am using the solution from dodald (https://stackoverflow.com/a/27510646/3179989) for formatting numbers with floating points and sign to make them aligned based on the floating point: textbox1.Text = String.Format("{0:+;-}{0,9:0.00000;0.00000}", number1); textbox2.Text = String.Format("{0:+;-}{0,9:0.00000;0.00000}", number2); textbox3.Text = String.Format("{0:+;-}{0,9:0.00000;0.00000}",

问题 I upload images to my App using Ajax and an Iframe. In Development everything works like a charm. But in production Nginx suddenly raises a 404 error. When I look into the log, the request never hits the Rails app. So I guess it has something to do with my Nginx configuration (maybe gzip compression). The failing requests is send to "/images.js". Any ideas on how to solve this? Google couldn't help me... My Nginx config: server { listen 80; server_name www.myapp.de; root /var/www/apps/myapp
