Answer 1

您可以简单地使用 read_csv() 和 sep=';'

您的示例数据不是很好，但我已尽力做到这一点。

我将其保存为 a.csv，代码如下：

In [1]: import pandas as pd

In [2]: pd.read_csv('a.csv', sep=';')
Out[2]:
   Seniority  Home  Time   Age  Marital  Records  Job  Expenses  Income  Assets  Debt  Amount  Price  Status
0        9.0   1.0  60.0  30.0      0.0      1.0  1.0      73.0   129.0     0.0   0.0     NaN    NaN     NaN
1       17.0   1.0  60.0  58.0      1.0      1.0  0.0      48.0   131.0     0.0   NaN     NaN    NaN     NaN
2       10.0   0.0  36.0  46.0      0.0      2.0  1.0      90.0   200.0  3000.0   NaN     NaN    NaN     NaN
3        0.0   1.0  60.0  24.0      1.0      1.0  0.0      63.0   182.0  2500.0   NaN     NaN    NaN     NaN
4        0.0   1.0  36.0  26.0      1.0      1.0  0.0      46.0   107.0     0.0   0.0     NaN    NaN     NaN
