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

Sometimes the problem is not how to use python, but with the raw data.
I got this error message

Error tokenizing data. C error: Expected 18 fields in line 72, saw 19.

It turned out that in the column description there were sometimes commas. This means that the CSV file needs to be cleaned up or another separator used.
