python - convert a list of objects to a list of a data member -


say have list of objects. object has data member 'name'. want sub list of objects have value of 'name'. elegant way beyond:

class person(base):     name = column(text)  p1 = person(name="joe") p2 = person(name="jill")  plst = [ p1, p2 ]  name_test = "jill"  found_people = list()  person in plst:     if person.name == name_test:         found_people.append(person) 

looking elegant solution not verbose. not sure if python code compiles or not :)

you use list comprehension.

class person(base):     name = column(text)  plist = [person(name="joe"), person(name="jill")]  found_people = [person person in plist if person.name == "jill"]
