os.path.dirname(__file__) returns empty

Question:

I want to get the path of the current directory under which a .py file is executed.

For example a simple file D:test.py with code:

import os

print os.getcwd()
print os.path.basename(__file__)
print os.path.abspath(__file__)
print os.path.dirname(__file__)

It is weird that the output is:

D:
test.py
D:test.py
EMPTY

I am expecting the same results from the getcwd() and path.dirname().

Given os.path.abspath = os.path.dirname + os.path.basename, why

os.path.dirname(__file__)

returns empty?

Answers:

Because os.path.abspath = os.path.dirname + os.path.basename does not hold. we rather have

os.path.dirname(filename) + os.path.basename(filename) == filename

Both dirname() and basename() only split the passed filename into components without taking into account the current directory. If you want to also consider the current directory, you have to do so explicitly.

To get the dirname of the absolute path, use

os.path.dirname(os.path.abspath(__file__))

print(os.path.join(os.path.dirname(__file__))) 

You can also use this way

import os.path

dirname = os.path.dirname(__file__) or '.'
Answered By: Deve

can be used also like that:

dirname(dirname(abspath(__file__)))
Answered By: adnan dogar
os.path.split(os.path.realpath(__file__))[0]

os.path.realpath(__file__)return the abspath of the current script; os.path.split(abspath)[0] return the current dir

I guess this is a straight forward code without the os module..

__file__.split(__file__.split("/")[-1])[0]

Since Python 3.4, you can use pathlib to get the current directory:

from pathlib import Path

# get parent directory
curr_dir = Path(__file__).parent

file_path = curr_dir.joinpath('otherfile.txt')
