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

Question

Error when reading a file containing backslashes

I have a csv-file with inside the rows string including "\" and "\\" inside the strings If i use pandas read_csv it is giving an error even with the right encoding. Even with various encodings i get different errors but none of them works. Only when i replace the backslash by another character it works.

any ideas?

Kind regards,

import pandas as pd

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

Testfile:

Answer 1

I think the main problem is that your file is not a CSV file - a " comma separated file", it is a CSV file - a " semi-colon separated file". So if you tell pandas csv_reader to delimit the fields with a semi-colon, the results should be much better.

import pandas as pd

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

Also, by the way, the reason you error in the original code on line 58 was because that was the first line with an actual comma in the line - all the other lines are read in as "one field" based on comma separated values, but this line gets split into more than one and then you have too many fields.

Answer 2

With another file i got a "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb3 in position 157936: invalid start byte" Error. The solution was to add file encoding cp1252 to the read_csv command

import pandas as pd

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

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