Question

我有产品CSV文件，我正在尝试使用pandas python读取此文件，但出现此错误

我的代码

import pandas as pd
df = pd.read_csv('D:\\work\\amazon\\move_in_links\\final.csv')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Compu City\AppData\Local\Programs\Python\Python38\lib\site-packages\pandas\io\parsers.py", line 676, in parser_f
    return _read(filepath_or_buffer, kwds)
  File "C:\Users\Compu City\AppData\Local\Programs\Python\Python38\lib\site-packages\pandas\io\parsers.py", line 454, in _read
    data = parser.read(nrows)

this is the link of file

另一件事，当我删除大多数行并仅保留读取文件的4行时。

Answer 1

默认情况下，pandas假定您的csv用逗号','分隔，您应该将适当的分隔符传递给read_csv调用。

import pandas as pd
df = pd.read_csv('D:\\work\\amazon\\move_in_links\\final.csv', sep=';')

Answer 2

文件似乎由;分隔。试试：

import pandas as pd
df = pd.read_csv('D:\\work\\amazon\\move_in_links\\final.csv',sep=";")
