如何在不导致程序崩溃的情况下结束if-else循环？

for i in range(10):
    if i == 5:
        break
    print(i)

def check_number(num):
    if num > 10:
        return "大于10"
    else:
        return "小于等于10"

result = check_number(15)
print(result)

flag = False
for i in range(10):
    if i == 5:
        flag = True
    if flag:
        break
    print(i)
