I'm on Problem set 3, problem 1. The question seems easy enough, but I keep getting stuck in a loop. For some reason I can't add to my start variable. Probably something simple, but if anyone has any suggestions I would appreciate it. Here's my code:
def countSubStringMatch(target,key):
start=0
count=0
ans = find(target,key,start)
while ans != 1:
start = start +ans +len(key)
count = count + 1
return count

Best ResponseYou've already chosen the best response.0The problem isn't your start variable, it's your ans variable. Your while loop will continue as long as ans != 1. Since ans is only assigned once (and not inside your loop) the value of ans does not change. Therefore if the program enters the loop initially (because ans is not 1) it will never be able to leave it (because ans will never be 1). Perhaps you want to add an additional call to find inside your loop?
