如何在Python中将浮点数转换为时间格式-分钟、秒和微秒？

import datetime

def float_to_time(float_num):
    minutes = int(float_num)
    seconds = int((float_num - minutes) * 60)
    microseconds = int(((float_num - minutes) * 60 - seconds) * 1000000)
    time_obj = datetime.time(0, minutes, seconds, microseconds)
    return time_obj

# 示例调用
float_num = 1.5
time_obj = float_to_time(float_num)
print(time_obj)
