Python Pandas NameError:未定义StringIO [英] Python pandas NameError: StringIO is not defined

问题描述

我无法读取Pandas中的数据: 输入:

I am unable to read data in Pandas: Input:

import pandas as pd

data = 'a,b,c\n1,2,3\n4,5,6'

pd.read_csv(StringIO(data),skipinitialspace=True)

输出:

NameError:name 'StringIO' is not defined

请让我知道为什么会发生错误，并让我知道要导入的内容.

Please let me know why the error occurred and also let me know what to import.

推荐答案

在此处找到解决方案:

发生错误是因为我没有导入StringIO.与Python 2不同，在Python 3中，您需要将其导入.

The error occurred because I didn't import StringIO. Unlike Python 2, in Python 3 you are required to import it.

from io import StringIO

导入后未发生任何错误. 上述问题的输出是:

After importing no error occurred. Output to the above question was:

   a b c
0  1 2 3
1  4 5 6

它也可以从同时适用于Python 2和3的pandas.compat导入.

It can also be imported from pandas.compat which works for both Python 2 and 3.

from pandas.compat import StringIO
