When I loaded it up, I got the following error:
Traceback (most recent call last):
File "C:\Python24\Account Tracker.py", line 82, in ?
load_file(accountlist)
File "C:\Python24\Account Tracker.py", line 10, in load_file
amount = line.next().strip()
AttributeError: 'str' object has no attribute 'next'
According to it, the 'str' object has no attribute 'next'. So how would I
load my file containing my data?
Relevant code:
def load_file(ac):
import os
filename = 'accounts.txt'
if os.path.exists(filename):
store = open(filename, 'r')
for line in store:
account = line.strip()
amount = line.next().strip()
ac[account] = amount
else:
store = open(filename, 'w')
store.close
Thanks.
