Python Pandas Error tokenizing data

Question

I\'m trying to use pandas to manipulate a .csv file but I get this error:

pandas.parser.CParserError: Error tokenizing data. C error: Expected 2 field

Answer 1

In my case, it is because the format of the first and last two lines of the csv file is different from the middle content of the file.

So what I do is open the csv file as a string, parse the content of the string, then use read_csv to get a dataframe.

import io
import pandas as pd

file = open(f'{file_path}/{file_name}', 'r')
content = file.read()

# change new line character from '\r\n' to '\n'
lines = content.replace('\r', '').split('\n')

# Remove the first and last 2 lines of the file
# StringIO can be considered as a file stored in memory
df = pd.read_csv(StringIO("\n".join(lines[2:-2])), header=None)
