get_attribute

This will only return the first attribute with the given name. To get other attributes of that name (for example, other TEL attributes if a contact has multiple telephone numbers), use get_attributes and iterate over the list searching for matching attributes.

This method iterates over all attributes in the VCard, so should not be called often. If extracting a large number of attributes from a vCard, it is more efficient to iterate once over the list returned by get_attributes.
