How to Get Only the Directory Path from a File's Absolute Path in Python?

How to Obtain the Full Directory Path of the Current File

In Python coding, acquiring the full directory path of the file being executed can be a crucial task. This question explores this topic, specifically aiming to extract the directory path while excluding the filename.

Understanding the Problem

The user has attempted to utilize the os.path.abspath(__file__) function to retrieve the file's absolute path. However, this approach yields the complete path, including the filename. The desired output is to obtain the directory path alone.

Pythonic Solutions

To resolve this challenge, Python offers multiple solutions:

Python 3

For the Directory of the Running Script:

import pathlib
pathlib.Path(__file__).parent.resolve()

For the Current Working Directory:

import pathlib
pathlib.Path().resolve()

Python 2 and 3

For the Directory of the Running Script:

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

For the Current Working Directory:

import os
os.path.abspath(os.getcwd())

Important Notes

• Ensure the usage of double underscores (__) before and after file.
• If the code is executed interactively or loaded from a non-file source, __file__ may not be available.
• The solutions provided assume that a Python script is being run from a file.
