The special variable __file__ contains the path to the current file. From that we can get the directory using either pathlib or the os.path module. Python 3. For the directory of the script being run: import pathlib pathlib.Path(__file__).parent.resolve() For the current working directory: import pathlib pathlib.Path().resolve() Python 2 and 3

In Python 3.4 and 3.5 that caused some pain, because open built-in function could only work with string or bytes objects, and did not support Path objects, so you had to convert Path objects to strings or use the Path.open() method, but the latter option required you to change old code:

getsourcefile(lambda:0) somehow gets the internal source file of the lambda function object, so returns '<pyshell#nn>' in the Python shell or returns the file path of the Python code currently being executed.

Sep 28, 2009 · I find it easier to use the following, since it makes it clear if the empty string ('') is in the path: python -c "import sys, pprint; pprint.pprint(sys.path)" ( And I found this answer more helpful, too; the title of the question mislead me into thinking it was about the actual path python was using, rather than the contents of the PYTHONPATH environment variable.)

Note that sys.argv[0] contains the full working directory (path) + filename whereas sys.path[0] is the current working directory without the filename. I have tested sys.path[0] on windows and it works.

Use this to get the path of the current file. It will resolve any symlinks in the path. import os file_path = os.path.realpath(__file__) This works fine on my mac. It won't work from the Python interpreter (you need to be executing a Python file).

FILENAME = str(os.path.basename(FULL_PATH_TO_SCRIPT)) FILENAME_NO_EXTENSION = os.path.splitext(FILENAME)[0] FILENAME_EXTENSION = os.path.splitext(FILENAME)[1] # the full path to the executable script being run EXECUTABLE_FULL_PATH = sys.argv[0] # the name of the executable being run EXECUTABLE_NAME = os.path.basename(EXECUTABLE_FULL_PATH ...

Apr 29, 2013 · @variable No, the paths in PYTHONPATH is added to the paths in sys.path when the Python interpreter starts. In other words, sys.path will include all the paths in PYTHONPATH, but also additional paths, like the path to the Python standard library …

Mar 15, 2009 · Fortunately, typing path at the windows path let me find where I had installed it. The path was an option when I installed Python which I just forgot. If you didn't select setting the path when you installed Python 3 that probably won't work - unless you manually updated the path when you installed it.

It should also be noted that this can return a relative filepath, so it should be used within the immediate current working directory context. Also if you run this from Windows and use a '\' delimited full path (e.g. python c:\path\to\directory\filepath.py), the result will incorrectly be blank. –
