If you've ever tried to learn Python consistently, you know the problem: you do a tutorial, feel great, then open your laptop three days later and have forgotten everything. That's why I built DuCode — a platform that gives you one Python coding challenge every day, tracks your streak, and rewards you with XP. ## How it works Every day a new challenge drops. You get a code snippet like this: def make_counter ( start = 0 ): def counter ( step = 1 , * , reset = False ): if reset : counter . _val = start return counter . _val counter . _val = getattr ( counter , ' _val ' , start ) + step return counter . _val counter . _val = start return counter c = make_counter ( 10 ) results = [ c (), c ( 2 ), c (), c ( reset = True ), c ( 3 ), c ()] print ( sum ( results )) Enter fullscreen mode Exit fullscreen mode And you have to figure out the output before the timer runs out. The faster you answer, the more XP you earn. Wrong answers cost XP — so it pays to think before you type.…
