Well, I'm learning python. I'm using my windows PC for it.
Now, here's what I'm putting in and the result:

>>> f=open('M:\programming\read.txt','r+')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
IOError: [Errno 2] No such file or directory: 'M:\\programming\read.txt'
>>>

I know that the file and location is right, I'm just not sure if I'm putting it in right. Thanks for any help.

'M:\\programming\read.txt'

you missed a backslash before read.txt

when dealing with paths, use raw strings:

(Toggle Plain Text)

f=open(r'M:\programming\read.txt','r+')

or use os.path:

(Toggle Plain Text)

import os
fname = os.path.join("M:\\", "whereever", "foo.txt")
f=open(fname, "r+")

--OH.
