将字典转换为数据帧

Question

我正在尝试将字典转换为数据帧。

import pandas as pd
dict = {'A': [1,2,3], 'B': [1,2,3,4])
pd.DataFrame.from_dict(dict, orient = 'index').T  

:

A        B
0   [1,2,3]  [1,2,3,4]

却得到了:

A      B
-----------
0  1      a
1  2      b
2  3      c
3  None   d

Answer 1

尝试将字典放入list ([]):

import pandas as pd
dct = {"A": [1, 2, 3], "B": [1, 2, 3, 4]}
df = pd.DataFrame([dct])
print(df)

打印:

A             B
0  [1, 2, 3]  [1, 2, 3, 4]

注意:变量名不要使用dict等保留字
