python分秒加减法

以下是使用strftime()和gmtime()函数将秒转换为时分秒的示例代码：

from time import gmtime, strftime

def seconds_to_hms(seconds):
    time_struct = gmtime(seconds)
    hms = strftime("%H:%M:%S", time_struct)
    return hms

seconds = 3666
hms = seconds_to_hms(seconds)
print("Time in HH:MM:SS format:", hms)  # 输出：Time in HH:MM:SS format: 01:01:06

以下是使用divmod()函数进行分秒加减法的示例代码：

def add_seconds(time, seconds):
    hours, minutes, old_seconds = map(int, time.split(':'))
    total_seconds = hours * 3600 + minutes * 60 + old_seconds
    new_total_seconds = total_seconds + seconds
    new_hours, remaining_seconds = divmod(new_total_seconds, 3600)
    new_minutes, new_seconds = divmod(remaining_seconds, 60)
    new_time = f"{new_hours:02d}:{new_minutes:02d}:{new_seconds:02d}"
    return new_time

time = "01:01:06"
seconds_to_add = 120
new_time = add_seconds(time, seconds_to_add)
print("New time after adding seconds:", new_time)  # 输出：New time after adding seconds: 01:03:06
