python – Find the current directory and files directory

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above wont work if youve already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

---

To get the current working directory use

import os
cwd = os.getcwd()

---

Documentation references for the modules, constants and functions used above:

• The os and os.path modules.
• The __file__ constant
• os.path.realpath(path) (returns the canonical path of the specified filename, eliminating any symbolic links encountered in the path)
• os.path.dirname(path) (returns the directory name of pathname path)
• os.getcwd() (returns a string representing the current working directory)
• os.chdir(path) (change the current working directory to path)

Current working directory: os.getcwd()

And the __file__ attribute can help you find out where the file you are executing is located. This Stack Overflow post explains everything: How do I get the path of the current executed file in Python?

You may find this useful as a reference:

import os

print(Path at terminal when executing this file)
print(os.getcwd() + n)

print(This file path, relative to os.getcwd())
print(__file__ + n)

print(This file full path (following symlinks))
full_path = os.path.realpath(__file__)
print(full_path + n)

print(This file directory and name)
path, filename = os.path.split(full_path)
print(path +  -->  + filename + n)

print(This file directory only)
print(os.path.dirname(full_path))
