我試圖根據(jù)if條件將列表追加到字典中。我為此問題編寫了一個(gè)工作函數(shù)，但我想以列表理解的形式編寫該程序。以下功能按月組織所有曲目。結(jié)果將是一個(gè)字典，以月為鍵，音軌為值。[[j for j in lst2] for i in month if j[-2] == i] #I tried this list comprehension code for my function given below列名稱[位置，曲目名稱，藝術(shù)家，流，Datetime.object，區(qū)域，月份，日期] Input : #my working code[['1','Starboy','The Weeknd','3135625',datetime.datetime(2017, 1, 1, 0, 0),  'global',1,1], ['2','Closer','The Chainsmokers','3015525',datetime.datetime(2017, 1, 1, 0, 0),  'global',1,1] ['3','Party Monster','The Weeknd','829599',datetime.datetime(2017, 2, 2, 0, 0),'  global',2,2]]def organized(lst2):    month = [1,2]    edict = {}    for i in month:        elst = []        for j in lst2:            if j[-2] == i:                elst.append(j)        edict[i] = elst    return edictoutput{1: [['1', 'Starboy', 'The Weeknd', '3135625',        datetime.datetime(2017, 1, 1, 0, 0),'global', 1, 1],     ['2', 'Closer', 'The Chainsmokers', '3015525',                                datetime.datetime(2017, 1, 1, 0, 0), 'global', 1, 1]] 2:[[‘3’, 'Party Monster', 'The Weeknd', '829599',        datetime.datetime(2017, 2, 2, 0, 0), 'global', 2, 2]]}
