Question

我已经尝试了几个小时才能读取此文件。我已经尝试研究解决方案并应用它们。他们没有工作。该文件本身可以在Excel上很好地打开，但是我不能用Pandas读取它。

响应不断返回相同的错误：ParserError: Expected 3 fields in line 5, saw 63

我还看到了有关此主题的其他一些问题，但是这些特定问题的解决方案都无法解决我的问题。

有人知道为什么我无法读取此文件以及如何解决该文件吗？谢谢

IN：

Answer 1

尝试在pd.read_csv（）中更改sep参数的值。

Answer 2

将代码更改为

data=pd.read_csv('API_EN.ATM.CO2E.PC_DS2_en_csv_v2_10181020.csv', header=None, engine='python', error_bad_lines=False)

将导入您的csv，但不会正确导入您的csv。您的csv和使用的分隔符可能存在某些问题。您能张贴要导入的csv的第5行吗？例如，最后一列是否包含带有逗号的文本？您期望多少列：3、63或其他？

我无法使用pd.read_csv使用不同数量的期望值来读取此CSV文件
