Question

为什么不将它们结合在一起

df = pd.DataFrame(metar_clouds_array[0],metar_clouds_array[1])
print(df) 

 metar_clouds_array =[[['OVC'], ['OVC'], ['OVC'], ['OVC'], ['OVC'], ['BKN', 'OVC'], ['BKN', 'OVC'], ['BKN', 'OVC'], ['BKN', 'OVC'], ['BKN', 'OVC'],['BKN', 'OVC'], ['OVC'], ['OVC'], ['OVC'], ['OVC'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['OVC'], ['BKN', 'BKN'], ['BKN', 'OVC'], ['FEW', 'BKN'], ['FEW', 'BKN'], ['FEW'], ['FEW', 'FEW'], ['FEW', 'SCT'], ['FEW', 'SCT'], ['FEW', 'SCT'], ['FEW', 'FEW', 'SCT'], ['FEW', 'FEW', 'SCT'], ['FEW', 'SCT']], [['014'], ['010'], ['008'], ['006'], ['005'], ['005', '012'], ['006', '012'], ['007', '014'], ['007', '014'], ['006', '012'], ['006', '012'], ['006'], ['004'], ['003'], ['002'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['-9999'], ['002'], ['003', '020'], ['003', '017'], ['003', '021'], ['003', '020'], ['025'], ['020', '150'], ['025', '250'], ['033', '250'], ['033', '250'], ['030', '150', '250'],['030', '150', '250'], ['150', '250']]]

但这会

dz = pd.DataFrame(metar_clouds_array[1])
print(dz)

dm = pd.DataFrame(metar_clouds_array[0])
print(dm)

我可以将DataFrames添加在一起吗？

我想知道为什么DataFrame然后将None放进去，因为它应该能够做到。这些是从表面观察得出的云高和云类型，我将它们存储在csv和txt文件中，以便以后进行比较。

没关系，我想通了。

result = pd.concat（[df，dm]，axis = 1，sort = False）
