>>> d8[0]

>>> d8[2]
{u'lix_edu_dev_override': u'control', u'fmt__school_highlight': u"St. Xavier's School Loyola Hall", u'degree': u'H.S.C.', u'i18n__detailed_school_page': u'More details for this school', u'lix_treasury_upload': u'B', u'fosList': [{u'link__fos_pivot': u'/search?search=&keywords=Science&sortCriteria=R&keepFacets=true&trk=prof-edu-field_of_study', u'fmt__fos_highlight': u'Science', u'name': u'Science', u'i18n__find_others': u'Find users with this keyword'}], u'enddate_iso': u'1988', u'fieldOfStudy': u'Science', u'link__peer_tracker_pivot_with_name': u'/college/?eduSchool=St%2E+Xavier%27s+School+Loyola+Hall&trk=prof-edu-school-name', u'educationId': 15978673, u'fmt__degree_highlight': u'H.S.C.', u'i18n__other_alumni': u"Find other members who attended St. Xavier's School Loyola Hall", u'startdate_iso': u'1976', u'schoolName': u"St. Xavier's School Loyola Hall", u'link__school_logo': u'/edu/school', u'lix_edu_profile_link': u'control', u'startdate_my': u'1976', u'enddate_my': u'1988', u'lix_edu_mvp_override': u'control'}

我想按“enddate\u iso”或“startdate\u iso”对列表进行排序（升序）。有可能吗？你知道吗

Answer 1

试一试：

>>> from operator import itemgetter
>>> sorted(d8, key=itemgetter('startdate_iso'))

sorted生成一个新列表。如果要就地排序，请使用sort()：

>>> d8.sort(key=itemgetter('startdate_iso'))
