I am currently accessing the parent directory of my file using Pathlib as follows:
Path(__file__).parent
When I print it, and this gives me the following output:
print('Parent: ', Path(__file__).parent)
#output
/home/user/EC/main-folder
The main-folder has a .env file which I want to access and for that I want to join the parent path with the .env. Right now, I did:
dotenv_path = os.path.join(Path(__file__).parent, ".env")
which works. But I would like to know, if there is a Pathlib alternate to os.path.join()?
Something like:
dotenv_path = pathlib_alternate_for_join(Path(__file__).parent, ".env")
Yes there is:
env_path = Path(__file__).parent / ".env"
/ is all you need. This will work in different OSs
You can use something like this:
(Path(__file__).parent).joinpath('.env')
Documentation:
Is the following definition of filepath closer in spirit to os.path.join?
import pathlib
main_dir = 'my_main_dir'
sub_dir = 'sub_dir'
fname = 'filename.tsv'
filepath = pathlib.PurePath(main_dir, sub_dir, fname)
You can simply join Path objects and strings:
import pathlib
script_parent_path = pathlib.Path(__file__).parent
my_dir = ".env"
my_new_path = pathlib.Path(script_parent_path, my_dir)
print(my_new_path)
That's because:
Pathlib's constructors accept pathsegments. Each element of pathsegments can be either a string representing a path segment, an object implementing the os.PathLike interface which returns a string, or another path object - https://docs.python.org/3/library/pathlib.html#pathlib.PurePath
