Question

在eof上读取带有read_csv的csv文件后，我的列的名称带引号：＆＃34; my_col＆＃34;。

我无法访问它：

df['"my_col"'] or df['my_col']

怎么可以访问它？我唯一能想到的就是改名。我可以逃避＆＃34;字符？

df.columns.tolist()
['\ufeff"COU"',
 'FAM',
  'CHI',
  'ER1',
  'ER2']

"COU","FAM","CHI","ER1","ER2","VAR","EMP","YEA","Unit Code","PowerCodeCode","Reference Period Code","Value","Flag Codes"
"AUS","SGL","0C","0P","NA","SA","EMP","2001",,"0",,9303,
"AUS","SGL","0C","0P","NA","SA","EMP","2002",,"0",,9594,
"AUS","SGL","0C","0P","NA","SA","EMP","2003",,"0",,9883,

Answer 1

在您的案例中阅读csv文件：正如@EdChum在评论中所建议的那样，您需要通过encoding='utf-16＆＃39;到read_csv

问题的下一部分：在引用dataFrame中的列时，您是否可以使用双引号字符（＆＃34;）？答案是肯定的。这是一个例子：

In [7]:

import pandas as pd
d = {
         '"one"': [1, 2, 3, 4, 5],
         '"two': [9, 8, 7, 6, 5]
    }
df = pd.DataFrame(d)

In [8]:
df['"one"']

Out[8]:
0    1
1    2
2    3
3    4
4    5
Name: "one", dtype: int64

In [9]:    
df['"two']

Out[9]:
0    9
1    8
2    7
3    6
4    5
Name: "two, dtype: int64
