在Python中将整数转换为字符串MM:SS

Question

我想知道是否有办法将整数的值转换成某种时间戳，就像使用strftime("%H:%M", gmtime())将输出当前的小时和分钟一样。你知道吗

我希望修复的代码片段如下所示：

#The full program includes an input system which makes this snippet run.
import time
initial_time = time.time()
print "It has been " + str(int(time.time()-initial_time)) + " since you said that."

假设程序运行时，整数的值是596，大约是9分56秒。我需要程序做的是输出09:56而不是596。如果有办法的话，请告诉我。你知道吗

另外，如果有办法使用格式化操作符%将str(int(time.time()-initial_time))引入字符串，请告诉我。你知道吗

Answer 1

timedelta是我处理这个问题的方式（正如其他人已经建议的那样）。但为了完整起见，我要提到模运算：

In [86]: import time

In [87]: initial_time = time.time()

In [88]: end_time = time.time()

In [89]: print "It has been %d:%d since you said that" %(int(end_time-initial_time)/60, int(end_time-initial_time)%60)
It has been 0:56 since you said that

此外，要解决您的问题：

In [90]: print "It has been", str(int(end_time-initial_time)/60) + ":" + str(int(end_time-initial_time)%60), "since you said that"
It has been 0:56 since you said that

Answer 2

In [1]: import datetime

In [2]: str(datetime.timedelta(seconds=596))
Out[2]: '0:09:56'

Answer 3

您可以使用^{}：

>>> import datetime
>>> str(datetime.timedelta(seconds=596))
'0:09:56'
