Numpy: Checking if a value is NaT

Question

nat = np.datetime64(\'NaT\')
nat == nat
>> FutureWarning: In the future, \'NAT == x\' and \'x == NAT\' will always be False.

np.isnan(nat)
>> TypeError:         


        

Answer 1

Another way would be to catch the exeption:

def is_nat(npdatetime):
    try:
        npdatetime.strftime('%x')
        return False
    except:
        return True
