两次相加，结果是0

Question

def add_two(h,m):

    try:
        att1 = datetime.strptime(h,"%H:%M %p")
        result = att1 + timedelta(minutes=int(m))   
        return result.strftime("%H:%M")
    except:
        return 0

结果为0

Answer 1

“try”实际上并不起作用-它只是确认它是有效的。你知道吗

像这样使用else:：

else:
    att1 = datetime.strptime(h,"%H:%M %p")
    result = att1 + timedelta(minutes=int(m))

Answer 2

尝试此更新

import datetime

try:
    att1 = datetime.datetime.strptime(h,"%H:%M %p")
    result = att1 + datetime.timedelta(minutes=int(m))
    return result.strftime("%H:%M")
expect:
    return 0
