[Solved] CSV IO python: converting a csv file into a list of lists

by 


in your data '2,2' is one string. But csv reader can deal with this:
import csv
result = []
with open("data", 'r') as f:
        r = csv.reader(f, delimiter=",")
        # next(r, None)  # skip the headers
        for row in r:
            result.append(row)

print(result)

[["'1'", "'2'", "'3'"], ["'1", "1'", "'2", "2'", "'3", '3']]
