我正在将多个JSON对象读入一个DataFrame.问题是某些列是列表.此外,数据非常大,因此我不能使用互联网上的可用解决方案.它们非常慢并且内存效率低
以下是我的数据的样子:
df = pd.DataFrame({'A': ['x1','x2','x3', 'x4'], 'B':[['v1','v2'],['v3','v4'],['v5','v6'],['v7','v8']], 'C':[['c1','c2'],['c3','c4'],['c5','c6'],['c7','c8']],'D':[['d1','d2'],['d3','d4'],['d5','d6'],['d7','d8']], 'E':[['e1','e2'],['e3','e4'],['e5','e6'],['e7','e8']]})
A B C D E
0 x1 [v1, v2] [c1, c2] [d1, d2] [e1, e2]
1 x2 [v3, v4] [c3, c4] [d3, d4] [e3, e4]
2 x3 [v5, v6] [c5, c6] [d5, d6] [e5, e6]
3 x4 [v7, v8] [c7, c8] [d7, d8] [e7, e8]
这是我的数据形状:(441079,12)
我想要的输出是:
A B C D E
0 x1 v1 c1 d1 e1
0 x1 v2 c2 d2 e2
1 x2 v3 c3 d3 e3 …
