obspy.core.event.catalog.Catalog.copy

Catalog.copy()

Returns a deepcopy of the Catalog object.

Return type:

Catalog

Returns:

Copy of current catalog.

Examples

1. Create a Catalog and copy it

   >>> from obspy.core.event import read_events
   >>> cat = read_events()
   >>> cat2 = cat.copy()
   

   The two objects are not the same:

   >>> cat is cat2
   False
   

   But they have equal data:

   >>> cat == cat2
   True
   

2. The following example shows how to make an alias but not copy the data. Any changes on cat3 would also change the contents of cat.

   >>> cat3 = cat
   >>> cat is cat3
   True
   >>> cat == cat3
   True
