我怎樣才能把df1變成df2？df1 = pd.DataFrame( { 'item1_aspect1' : ["a", "b", "c"], 'item1_aspect2' : [1,2,3], 'item1_aspect3' : ["[12,34]", "[56,78]", "[99,10]"], 'item2_aspect1' : ["a", "b", "c"], 'item2_aspect2' : [1,2,3], 'item2_aspect3' : ["[12,34]", "[56,78]", "[99,10]"], 'item3_aspect1' : ["a", "b", "c"], 'item3_aspect2' : [1,2,3], 'item3_aspect3' : ["[12,34]", "[56,78]", "[99,10]"] })df2 = pd.DataFrame({ 'aspect_1' : ["a", "b", "c", "a", "b", "c", "a", "b", "c"], 'aspect_2' : [1,2,3,1,2,3,1,2,3], 'aspect_3' : ["[12,34]", "[56,78]", "[99,10]", "[12,34]", "[56,78]", "[99,10]", "[12,34]", "[56,78]", "[99,10]"]})即列名是一個(gè)標(biāo)識(shí)符，它分成幾行。我不知道該怎么做。
我如何將這個(gè)數(shù)據(jù)框轉(zhuǎn)入這個(gè)數(shù)據(jù)框？
