Here is the syntax to override def copy function in your module:

def copy(self, cr, uid, id, default=None, context=None):
"""
Duplicate record with given id updating it with default values
:param default: dictionary of field values to override in the original values of the copied record, e.g: ``{'field_name': overriden_value, ...}``
:type default: dictionary
"""
if default is None:
default = {}
#Todo code (You can pass your value of any field in default)
default.update({'your_field': value})

with new api:
@api.one
def copy(self, default=None):
default = dict(default or {})
default.update({
'[field you want to change the default value of]': '[value you want]',
})
return super([class you are changing], self).copy(default)

Write a new function that overrides the original one and calls the original with your changes:

def copy(self, cr, uid, id, default={}, context=None):
if not default:
default = {}
default.update({
'[field you want to change the default value of]': '[value you want]',
})
return super([class you are changing], self).copy(cr, uid, id, default, context=context)`
