Finding a file's directory address on a Mac

Question

I am working with a Macbook programming python. What I want to know is how I can access certain files using Python\'s file functions. A google search failed me.

For exam

Answer 1

f = open (r"/Users/USERNAME/Desktop/somedir/somefile.txt")

or even better

import os
f = open (os.path.expanduser("~/Desktop/somedir/somefile.txt"))

Because on bash (the default shell on Mac Os X) ~/ represents the user's home directory.

Answer 2

If this is still an issue, I had the same problem and called Apple. I learned that the file I'd created was saved on iCloud. The Apple guy told me to save the file locally. I did that and the problem was solved.

Answer 3

You're working on a Mac so paths like "a/b/c.text" are fine, but if you use Windows in the future, you'll have to change all the '/' to '\'. If you want to be more portable and platform-agnostic from the beginning, you better use the os.path.join operator:

import os

desktop = os.path.join(os.path.expanduser("~"), "Desktop")
filePath = os.path.join(desktop, "somefile.txt")

f = open(filePath)

Answer 4

The desktop is just a subdirectory of the user’s home directory. Because the latter is not fixed, use something like os.path.expanduser to keep the code generic. For example, to read a file called somefile.txt that resides on the desktop, use

import os
f = open(os.path.expanduser("~/Desktop/somefile.txt"))

If you want this to be portable across operating systems, you have to find out where the desktop directory is located on each system separately.
