python - 我如何使用 % 在 Python 中将秒转换为分钟和秒

Question

def main():
    import math
    print('Period of a pendulum')
    Earth_gravity = 9.8
    Mars_gravity = 3.7263
    Jupiter_gravity = 23.12
    print('     ')
    pen = float(input('How long is the pendulum (m)? '))
    if pen < 0:
        print('illegal length, length set to 1')
        pen = 1
        period1 = (2 * 3.14159265359) * math.sqrt(pen / Earth_gravity)
        period2 = (2 * 3.14159265359) * math.sqrt(pen / Mars_gravity)
        period3 = (2 * 3.14159265359) * math.sqrt(pen / Jupiter_gravity)        
        print('     ')
        print('The period is', round(period1,3))
        minutes1 = period1 / 60
        minutes2 = period1 / 60
        minutes3 = period1 / 60
        seconds1 = minutes1 % 60
        seconds2 = minutes2 % 60
        print('or', round(minutes1,1), 'minutes and', seconds, 'seconds on 
Earth')
        print('     ')
        print('The period is', round(period2,3))
        print('or', round(minutes2,1), 'minutes and', seconds, 'seconds on 
Mars')
        print('     ')
        print('The period is', round(period3,3))
        print('or', round(minutes3,1), 'minutes and', seconds, 'seconds on 
Jupiter')        
    else:
        period1 = (2 * 3.14159265359) * math.sqrt(pen / Earth_gravity)
        period2 = (2 * 3.14159265359) * math.sqrt(pen / Mars_gravity)
        period3 = (2 * 3.14159265359) * math.sqrt(pen / Jupiter_gravity)        
        print('     ')
        print('The period is', round(period1,3))
        minutes1 = period1 // 60
        minutes2 = period2 // 60
        minutes3 = period3 // 60
        seconds1 = minutes1 % 60
        seconds2 = minutes2 % 60
        seconds3 = minutes3 % 60
        print('or', round(minutes1,1), 'minutes and', seconds1, 'seconds on 
Earth')
        print('     ')
        print('The period is', round(period2,3))
        print('or', round(minutes2,1), 'minutes and', seconds2, 'seconds on 
Mars')
        print('     ')
        print('The period is', round(period3,3))
        print('or', round(minutes3,1), 'minutes and', seconds3, 'seconds on Jupiter')        

main()

好的，所以我需要将秒数转换为秒数和分钟数。我不确定如何使用 % 来获取输出中的秒数和分钟数。我需要在此使用//和 %。我对此很陌生，所以如果草率或矫枉过正，我深表歉意。困惑的区域是包含 % 的行。谢谢!

您可以简单地使用 divmod它返回整数除数和模数，非常适合您的情况:

>>> seconds = 1000
>>> minutes, seconds = divmod(seconds, 60)
>>> hours, minutes = divmod(minutes, 60)
>>> days, hours = divmod(hours, 24)
>>> days, hours, minutes, seconds
(0, 0, 16, 40)

似乎您只需要第一行 minutes, seconds = divmod(seconds, 60) 但我想展示如果还有更多转换，如何使用它。 :)
