numpy 日期问题 - 将浮点年-周格式转换为 numpy 的日期格式

Question

I have a floating point value representing the date with year-week format as follows:

201423.0000

where the 2014 is the year and 23 is the week number. How can I convert this floating point value to numpy's datetime format ?

Answer 1

Here is one way:

In [43]: a = 201423.0000

In [48]: date = np.datetime64(str(int(a // 100)), 'Y') + np.timedelta64(int(a%100), 'W')

In [49]: date
Out[49]: numpy.datetime64('2014-06-05')
