在Python中，如何使用%将秒转换为分钟和秒

main()

好的，我需要把秒转换成秒和分。我不知道如何使用%来获得输出中的秒和分。我需要在这里使用//and%。我在这方面很新，所以我道歉，如果它是草率或过度。混乱的区域是包含%的行。谢谢您！在

整数将向下舍入到最接近的整数。%或模运算符只报告除法运算的剩余部分。在

所以135%60返回15。这是因为60比135大两倍，而剩下的15比60少。60到135的两次运算不会返回，因此需要使用标准除法运算符来查找该值。在

您可以除以60得到分钟，然后还可以使用模运算符返回剩余的秒数。在

time = 135

minutes = time / 60
seconds = time % 60

print minutes
print seconds
