有这样的代码

def late(now, classes, bus):
    now = now.split(':')
    now = timedelta(days=0, hours=int(now[0]), minutes=int(now[1]) + 5)
    classes = classes.split(':')
    classes = timedelta(hours=int(classes[0]), minutes=int(classes[1]))
    for i in bus:
        times = now + timedelta(minutes=15)
        print(times)
        if times < classes:
            return f'Выйти через {i} минут'
    return 'Опаздание'

print(late('12:00', '12:40', [0, 1, 4, 6, 25]))

下面是一个例子，他考虑你是否有时间去上学。首先是现在几点。第二个参数是课程的开始时间。第三个是公共汽车到达的时间（以分钟计）。同时，出去需要5分钟，到那里需要15分钟。一切都很完美，但是timedelta在pm中计算，而不是在am中。如何补充代码以使 timedelta 正确计数。

她让我完全走投无路。我什么都不懂，我明白这很嚣张，但我从来没有陷入过这样的死胡同。怎么算？条件中的 N - 1 是多少？非常混乱。我不是在寻求解决方案，而是寻求帮助解释。

再次假设有 N 个车站和它们之间的票价表。需要找到所有这样的站点对，在这些站点中，通过某个第三个站点的一次换乘比直接从一个站点到另一个站点更便宜。输入格式

输入格式 在第一行输入一个自然数 N — 站数。其后是 N-1 行，占价格表的一半，与本主题前面的问题一样。输出格式

输出格式 显示满足条件的站号对列表（每对由空格分隔）。对必须按第一个数字升序排序，然后按第二个数字，并且不得重复，包括改变对中数字的顺序。

我会尽我所能。我立即为计算机的名称道歉，它发生了：/

我警告你，不要为胆小的人阅读！是的，我一直在学习这门语言，要么是语法错误，要么是空格。函数出错，翻遍了一切，但没有找到答案。也许我不擅长谷歌，或者这样的编译器......

znak = input()
a = input()
b = input()
print (str(znak))
print (int(a))
print (int(b))
if znak == "+":
   plus(1)
elif znak == "-":
   plus(2)
else:
   plus(3)
def plus(znaktyt):
   if znaktyt == 1:
      c = a+b
      print(c)
   break
    elif znaktyt == 2:
      c = a-b
      print(c)
     break
     elif znaktyt == 3:
        print("error")
     break
