Find current directory and file's directory

Question

In Python What command can I use to find these:

•     Location of file which I am executing, and
•     Current directory (where I was in the terminal at the time I ran the script in Python)

Answer 1

To get the path to the directory where the Python file is stored write the code below in that file:

import os 

directory_path = os.path.dirname(os.path.realpath(__file__))

The above code may fail if you have already used os.chdir() to change the working of your current directory because the value of _file_ constant is relative with the current working directory and does not change by an os.chdir() call.

If you want to get the current working directory use the following code:

import os

cw_d = os.getcwd()

Here, os.getcwd() returns a string representing the current working directory. 

Hope it helps!

Answer 2

By using the below-mentioned code you  can find the current directory in Python:-

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))
