将浮点数转换为hh：mm格式 [英] Converting a float to hh:mm format

问题描述

我想以hh：mm格式以时间字符串形式打印经过数学运算后得到的浮点值。目前，我有9.888888888888886之类的浮动货币，我想按09:50之类的时间发布。我尝试了以下代码：

I want to print a float value that I've got after performing some math as time string in the hh:mm format. Currently I have the float like 9.888888888888886 and I want it in time like 09:50. I have tried the following code:

    time = str(time)
    time = time.split(".")
    time[1] = float(time[1])
    time[1] *= 0.6
    time[1] = str(time[1])

打印时我使用

    str(time[0]) + ":" + time[1][:2]

有什么办法能够持续地达到这种效果吗？如果使用更高级的输入，上述代码将无法正常工作，并输出错误的时间。

Any way to achieve this effect consistently? With more advanced inputs my above code does not work properly, and outputs the wrong time.

推荐答案

或者使用 datetime ，您可以使用带有一些数学运算的简单格式，例如：

Alternatively to using datetime, you can just use simple formatting with a bit of maths, eg:

result = '{0:02.0f}:{1:02.0f}'.format(*divmod(time * 60, 60))
