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

An alternative that I have found to be useful in dealing with similar parsing errors uses the CSV module to re-route data into a pandas df. For example:

import csv
import pandas as pd
path = 'C:/FileLocation/'
file = 'filename.csv'
f = open(path+file,'rt')
reader = csv.reader(f)

#once contents are available, I then put them in a list
csv_list = []
for l in reader:
    csv_list.append(l)
f.close()
#now pandas has no problem getting into a df
df = pd.DataFrame(csv_list)

I find the CSV module to be a bit more robust to poorly formatted comma separated files and so have had success with this route to address issues like these.
