Answer 1

You need to append each row to the lstneedssorted list. You can use the csv module to automatically parse the CSV file, instead of using .strip().split(',') When sorting, you use the key option to specify how to get the sort key from each item. In this case, the date is line[2]. import csv lstneedssorted = [] with open("file3.txt") as f3: c = csv.reader(f3) for lx in c: lstneedssorted.append(lx) lstneedssorted.sort(key = lambda line: line[2]) print(lstneedssorted)
