NumPy's datetime_data(~) method extracts information about the unit as well as the step-size.

WARNING

Due to a lack of explanation in the official documentation, we do not understand what the step-size means.

Parameters

1. dtype | string or type

The datetime from which to extract information.

Return value

A tuple that contains the following:

The unit given as a string
The steps-size given as an integer

Examples

To extract the units from an existing datetime64 object:


        
        
            
                
                
                    dt = np.datetime64(np."2020-05-25")
np.datetime_data(dt)
                
            
            ('D', 1)

Here, the output tells us that our datetime has a unit of days (i.e. "D"). Again, we're not too sure what the first unit is about, so if you have any insights, we'd love to talk with you!

To extract the units from an existing timedelta64 object:


        
        
            
                
                
                    td = np.timedelta(20, "s")
np.datetime_data(td)
                
            
            ('s', 1)
