Question

    for i in range(len(routes)):
        if routes[i] == location:
              routes.remove(routes[i])
    return routes
         


        

Answer 1

It's very simple. Just use break statement in the loop. So that the loop stops iterating once it satisfies the if condition for the first time. Using remove() is better but if you want to use loop in your code. This might be the answer.

def drop dest(routes,location):
for i in range(len(routes)):
    if routes[i] == location:
          routes.remove(routes[i])
          break
return routes
