我在用 python 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

现在用python加载后,out文件变成了这样:

     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与相应的数据对齐。

谢谢

最佳答案

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())

通过评论编辑:

print (df)
cand_id cand_name cand_age cand_sex
0 A1 Adam 35 M
1 A2 Max 31 M
2 A3 Uma 32 F
3 B1 Jack 29 M
4 B2 Maya 30 F

print (df.ix[2])
cand_id A3
cand_name Uma
cand_age 32
cand_sex F
Name: 2, dtype: object

df.set_index('cand_id', inplace=True)
print (df.ix['A3'])
cand_name Uma
cand_age 32
cand_sex F
Name: A3, dtype: object
