Python Pathlib - path with spaces issue

Question

I have a filesystem path setup like this where a directory name with spaces is symlinked to a directory with no spaces (to try and circumvent issues such as this):

$ ls -lR
drwxr-xr-x  3 user  group    96 Nov 25 15:37 with - spaces/
lrwxr-xr-x  1 user  group    18 Nov 25 15:28 with_no_spaces@ -> /tmp/with - spaces
./with - spaces:
total 0
drwxr-xr-x  5 user  group  160 Nov 25 15:37 dir1/

./with - spaces/dir1:
total 0
-rw-r--r--  1 user  group  0 Nov 25 15:37 a
-rw-r--r--  1 user  group  0 Nov 25 15:37 b
-rw-r--r--  1 user  group  0 Nov 25 15:37 c

I would like to use the pathlib module to iterate over the a, b, c files in dir1 and get the absolute path of each.

$ pwd
/private/tmp/with - spaces/dir1

import pathlib
p = pathlib.Path(".")
file_names = [_file.absolute().as_posix() for _file in p.iterdir()]
print(file_names)
#['/private/tmp/with - spaces/dir1/a',
# '/private/tmp/with - spaces/dir1/c',
# '/private/tmp/with - spaces/dir1/b']

This works as expected but these file paths are then consumed by a downstream system (spark) and causes issues because of the paths with spaces. Is there a platform-agnostic way to handle this with pathlib or maybe escape characters, or something else?

Using python 3.7.4

Thanks.

Answer 1

I can't really pin it down since your code is working as it should, and you didn't detail how the down stream works. However, in most platforms, path arguments with spaces in them are usually fine as long as they are in double quotes.

So try this (assuming python 3.6+):

file_names = [f'"{_file.absolute().as_posix()}"' for _file in p.iterdir()]

Or this for all python versions:

file_names = ['"' + _file.absolute().as_posix() + '"' for _file in p.iterdir()]

你应该替换你的空格.replace(" ", "\\\\ ");
