Hi,
I'm using xarray to read netcdf data and I had to time in my data the
values:
xarray.DataArray 'time' (time: 507)>
array(['1979-01-01T00:00:00.0', '1979-02-01T00:00:00.0',
'1979-03-01T00:00:00.0', ...,
'2021-01-01T00:00:00.0',
'2021-02-01T00:00:00.0', '2021-03-01T00:00:00.0'],
dtype='datetime64[ns]')
Please, how can I get the years and months values from this array.
Thanks,

Hi,
maybe this :
from datetime import datetime
import time
# Convert Event to a string
Event="1979-01-01T00:00:00.0"
strDate=time.strftime(Event)
print("Date string ",strDate)
# Get the Year from the string strDate
print("Year ",strDate[0:4])
# Get the month from the string strDate
print("Month ",strDate[5:7])
print()
#
# Convert Event to a datetime object
Event="1979-01-01T00:00:00.0"
dtmDate=datetime.strptime(Event,"%Y-%m-%dT%H:%M:%S.0")
print("datetime object",dtmDate)
# Get the Year from the datetime object
print("Year ",dtmDate.year)
# Get the month from the datetime object
print("Month ",dtmDate.month)

Looks like your "time" values are ISO-8601 dates, stored as strings.
You should be able to parse them easily by hand, or hand them to
datetime.datetime.fromisoformat().
The dtype is a strong hint that there is a numpy or pandas datetime
object underneath the misleading repr().
Assuming that x is the column array I'd try
[d.year for d in x]
or
x.map(operator.attrgetter("year"))
