How to convert numpy.timedelta64 to minutes
提问by Behzad Shahbaz
I have a date time column in a Pandas DataFrame and I'd like to convert it to minutes or seconds.
我在 Pandas DataFrame 中有一个日期时间列，我想将其转换为分钟或秒。
For example: I want to convert 00:27:00to 27 mins.
例如：我想转换00:27:00为 27 分钟。
example = data['duration'][0]
example
result: numpy.timedelta64(1620000000000,'ns')
结果： numpy.timedelta64(1620000000000,'ns')
What's the best way to achieve this?
实现这一目标的最佳方法是什么？

Use array.astype()to convert the type of an array safely:
用于array.astype()安全地转换数组的类型：
>>> import numpy as np
>>> a = np.timedelta64(1620000000000,'ns')
>>> a.astype('timedelta64[m]')
numpy.timedelta64(27,'m')
