Python open() Mac OS X Komodo Edit

Question

I started now to learn Python, so my question is kinda stupid

I have this piece of code

#!/usr/local/bin/python3
# encoding: utf-8

fh = open("lines.txt")

for lines in readlines():
    print(lines)

the text file lines.txt exits and it is at the same directory of my page, I using Komodo Edit, when I run the file, I get this error.

    Traceback (most recent call last):
  File "/Users/Jeff/Sites/PythonLearning/forloop.py", line 4, in <module>
    fh = open("lines.txt")
IOError: [Errno 2] No such file or directory: 'lines.txt'

Funny thing, if i open this file in IDLE, it works nicely, as well if I open in Mac os X terminal!

Thanks a lot!!

+1 for using Komodo, my favorite editor for Python! – Gabe Mar 27 '11 at 01:58 — Gabe, Mar 27 '11 at 01:58

You're getting this error because by default when you run a script in Komodo Edit it does not run it from the directory the script is saved in (unlike when you run normally from the command terminal).

To fix this - when you select the 'Run Command' option in Komodo Edit - Click 'More' to bring down a further options list and then in the 'Start In' field enter %D. This tells Komodo to run the script from the directory it is in and should solve your problem.

Use print os.getcwd() to find out what's your working directory. It'd probably not what you expect.

@Jeff Dias: Please read a tutorial. You need to import `os`. – S.Lott Mar 27 '11 at 01:47
