Question

我在python中处理它时有一个CSV文件我面临以下问题：

CSV文件：

   cand_id   cand_name   cand_age   cand_sex
      A1         Adam        35         M
      A2         Max         31         M
      A3         Uma         32         F
      B1         Jack        29         M
      B2         Maya        30         F

现在在python中加载后，out文件就变成了这样：

     cand_id   cand_name   cand_age   cand_sex
       Adam        35         M          NaN
       Max         31         M          NaN
       Uma         32         F          NaN
       Jack        29         M          NaN
       Maya        30         F          Nan

请告诉我如何将正确的列名称与相应的数据对齐。

您需要将参数index_col=False添加到read_csv：

import pandas as pd

df = pd.read_csv('P00000001-AL.csv', index_col=False)

print (df.head())

列名和相应的数据在python中不匹配
