Error when verifying folder creation (Python)

Question

I am stuck in an "error" during my folder creation.
First of all, this is the code I am using:

import os

import errno

import subprocess



try:

    folder = os.makedirs(os.path.expanduser('~\\Desktop\\FOLDER'))

except OSError as e:

    if e.errno != errno.EEXIST:

        raise

print(os.path.isdir('~\\Desktop\\FOLDER'), '- FOLDER CREATED')

So, the code do the following:

using
os.makedirs()
it creates a new folder on Desktop. I want to create a folder which use cross-platform path, so I am using
~
symbol

using
print()
I want to verify that the folder really exist, that the directory is real. The output of this is
True
or
False
.

The problem is: if I am using the

~

symbol in

print()

, the output is

False

. If I put the complete path to the folder (ex:

os.path.isdir('C:\\Users\\Bob\\Desktop\\FOLDER')

, the output is

True

.

Why does this happen ? The folder is really created even if I have a False output ?

You are just missing the expanduser method when calling isdir:

print(os.path.isdir(os.path.expanduser('~\\Desktop\\FOLDER')), '- FOLDER CREATED')

You don't really need the check at the end as well. Since if there is no exception, you can be sure that the creation is successful.

Here is a cleaner implementation:

try:
    dirpath = os.path.expanduser('~\\Desktop\\FOLDER')
    os.makedirs(dirpath)
    print dirpath, "creation successful"
except OSError as e:
    print dirpath, "creation failed"
    if e.errno != errno.EEXIST:
        raise
