I wrote the following code to read out a bill from a file and then putting it into a bills-list.
The bill contains: "company", "customer", Year, Month, Day, Amount, "credit/debit"
Is there a nicer way using list comprehension to make this code look better?
def read_bills(file = "bills.csv"): """Read bills from the file system 'bills.csv'""" # Create a list in which each bill is entered. bills =  for line in open(file): bill = line.strip().split(',') for i in range(len(bill)): if i > 1 and i < 5: bill[i] = int(bill[i].strip()) elif i == 5: bill[i] = float(bill[i].strip()) else: bill[i] = bill[i].strip() bills.append(bill) return bills
