seconds

I'm learing Python and Pygame, and my first thing I'm making is a simple Snake game. I'm trying to make it so that the snake moves once every 0.25 seconds. Here is the part of my code that loops: while True: check_for_quit() clear_screen() draw_snake() draw_food() check_for_direction_change() move_snake() #How do I make it so that this loop runs at normal speed, but move_snake() only executes once every 0.25 seconds? pygame.display.update() I want all of the other function to run normally, but move_snake() to only occur once every 0.25 seconds. I've looked it up and found a few answers but

I've got an amount of seconds that passed from a certain event. It's stored in a NSTimeInterval data type. I want to convert it into minutes and seconds . For example I have: "326.4" seconds and I want to convert it into the following string: "5:26". What is the best way to achieve this goal? Thanks. pseudo-code: minutes = floor(326.4/60) seconds = round(326.4 - minutes * 60) Brief Description The answer from Brian Ramsay is more convenient if you only want to convert to minutes. If you want Cocoa API do it for you and convert your NSTimeInterval not only to minutes but also to days, months,

I want to parse a hh:mm:ss string. A simple one is ([0-1]?\d|2[0-3]):([0-5]?\d):([0-5]?\d) which expects 2:3:24 or 02:03:24 string. I want to take it a step further and pass the validation even in cases like if you enter just 56, it should be pass, as 56 can be considered as 56 secs [SS] if you enter 2:3 or 02:03 or 02:3 or 2:03 it should pass. 2 minutes and 3 seconds [MM:SS] If you enter 20:30:12 pass with 20 hrs, 30 minutes and 12 secs [HH:MM:SS] if you enter 78:12 , do not pass 78 minutes is wrong.... Basically, if one ":" is found, consider number before ":" as MM and number after ":" as
