dt = matlab.datetime.compatibility.convertDatenum(d) dt =datetime02-Jan-2022 This function also converts serial date numbers. Create a serial date number and convert it to adatetimevalue. d = datenum(d) d = 738523 dt = matlab.datetime.compatibility.convertDatenum(d) ...
然后,创建一个datetime64数组: dt_array = np.array(['2022-01-01', '2022-01-02', '2022-01-03'], dtype='datetime64') 接下来,使用astype()函数将datetime64数组转换为整数: int_array = dt_array.astype(np.int64) 最后,打印转换后的整数数组: print(int_array) 这样就可以将datetime64数组转换为...

return sum(int(digit) for digit in str(n)) months = [ {'year': 1900, 'first_day': datetime.datetime(1900, 1, 1)}, {'year': 1901, 'first_day': datetime.datetime(1901, 1, 1)}, {'year': 1902, 'first_day': datetime.datetime(1902, 1, 1)}, {'year': 1903, 'first_day'...
Thus, MATLAB and Python users should be cautious when using datetime-fortran's date2num() function.Since version 1.0.5, date2num is timezone aware, i.e. the datetime instance is first converted to UTC before calculating the number of days....
