sir, what seemed to be the problem with this:
def process(list_of_lines): data_points = [] for line in list_of_lines: data_points.append(int(line)) return data_points
data_file = open('C:/Documents and Settings/nyer/Desktop/nyer.txt', 'r') data = data_file.readline()
print process(data)
<SNIP>
Traceback (most recent call last):
File "C:\Python23\practices\opentxt", line 12, in -toplevel-
process(data)
File "C:\Python23\practices\opentxt", line 6, in process
data_points.append(int(line))
ValueError: invalid literal for int():
The immediate one, due to my advice, is that each line of your file ends with a newline character ('\n'). So, you cannot call int on '1000\n'.
Bollocks! Nobody read any thing I write where I am claiming to answer anyone!
IDLE 1.1
>>> int('1000\n')
1000
>>>So, sorry, I don't know what's wrong with the code you sent me, and I fear that if I tried to work it out, I'd do more damage. I yield the floor as I am off to write "Don't post untested code 1000 times.
(I will say I suspect it is the readline vs. readlines, but then hopefully no one is reading this ;-)
Sheepishly,
bran vdB
