Why does my while loop not stop？

Question

RANDOM_COR=random.randrange(5,6) 

def check_xy_data():     

    global COUNT 
    COUNT=0 

    input_xy=input("input(x,y) : ") 

    think_xy=list(map(int,input_xy.split(","))) 

    if(random_array[think_xy[0]][think_xy[1]] == "C"): 
     screen_array[think_xy[0]][think_xy[1]] = "O" 
     COUNT=COUNT+1 
    else: 
     screen_array[think_xy[0]][think_xy[1]] = "X" 



def main(): 

    make_intro() 

    init_screen_array() 
    init_random_array() 

    make_random_num(RANDOM_COR) 


    while(True): 
     check_xy_data() 

     draw_outline_start(TOTAL_COL_NUM//2) 

     draw_out_rowline(TOTAL_COL_NUM//2, "Input : ") 
     draw_out_rowline(TOTAL_COL_NUM//2, "Correct : ") 
     draw_out_rowline(TOTAL_COL_NUM//2, "Error : ") 
     draw_out_rowline(TOTAL_COL_NUM//2, "Total : ") 

     draw_outline_mid(TOTAL_COL_NUM//2) 
     if(COUNT==RANDOM_COR-1): 
      break 

The if at the bottom of my code is supposed to get me out of the while loop、but I'm stuck in an infinite loop。 Help？

Answer 1

Try this change：

RANDOM_COR=random.randrange(5,6) 
COUNT = 0 

def check_xy_data():     

    global COUNT 

With COUNT inside check_xy_data、you set it back to 0 on every call。 It can never reach more than 1 Your check is whether it's in the range 5-6 This is never true、so you can never leave the loop。

Note that trivial debugging skills would have found this：just stick a print statement before you test your loop condition、to see what the values are。 Use that next time ... :-)
