pandas 读取文件中带有反斜杠的 csv 文件时出现 read_csv 错误

Question

读取包含反斜杠的文件时出错

我有一个 csv 文件，行字符串内部包含“\”和“\\”如果我使用 pandas read_csv，即使使用正确的编码也会出错。 即使使用各种编码，我也会遇到不同的错误，但它们都不起作用。 只有当我用另一个字符替换反斜杠时它才有效。

有任何想法吗？

亲切的问候，

import pandas as pd

df = pd.DataFrame()
df = pd.read_csv(r'C:\testfile.csv',encoding="unicode_escape")
print(df.head())

Answer 1

我认为主要问题是您的文件不是 CSV 文件 - 一个“逗号分隔文件”，它是一个 CSV 文件 - 一个“分号分隔文件”。 因此，如果您告诉 pandas csv_reader 用分号分隔字段，结果应该会好得多。

import pandas as pd

df = pd.read_csv("test2.csv", delimiter=';')
print(df.head())

另外，顺便说一句，你在第 58 行的原始代码中出错的原因是因为那是第一行，该行中有一个实际的逗号 - 所有其他行都基于逗号分隔值作为“一个字段”读入，但是这条线被分成多个，然后你有太多的领域。

Answer 2

对于另一个文件，我得到了一个“UnicodeDecodeError：‘utf-8’编解码器无法解码 position 157936 中的字节 0xb3：无效的起始字节”错误。 解决方案是将文件编码 cp1252 添加到 read_csv 命令

import pandas as pd

df = pd.DataFrame()
file_encoding = 'cp1252'

df = pd.read_csv(r'C:\Testmap\testfilelarge.csv', delimiter=';',encoding = file_encoding)
