How to Specify a Directory Path in Python?

Estimated read time 2 min read

In Python, you can specify a directory path using a string that represents the absolute or relative path to the directory. There are two types of path representations: absolute and relative.

  1. Absolute path:

An absolute path is a complete path that specifies the full location of a file or directory on the file system. An absolute path starts with the root directory on the file system, which is represented by a forward slash (/) on Unix-based systems or a drive letter followed by a colon (C:) on Windows systems. Here’s an example of an absolute path:

path = '/Users/myuser/myproject/data/'

In this example, we specify an absolute path to a directory called data in the myproject directory, which is located in the home directory of the user myuser on a Unix-based system.

  1. Relative path:

A relative path specifies the location of a file or directory relative to the current working directory of your Python script. A relative path does not start with a forward slash (/) or a drive letter (C:), but rather with a directory name or a period (.) to represent the current directory. Here’s an example of a relative path:

path = 'data/'

In this example, we specify a relative path to a directory called data located in the same directory as our Python script.

Note that you can use the os.path module to manipulate and join paths in a platform-independent way. For example, to join a directory path and a file name, you can use the os.path.join() function:

import os

dir_path = '/Users/myuser/myproject/data'
file_name = 'myfile.txt'

file_path = os.path.join(dir_path, file_name)

In this example, we use the os.path.join() function to join the dir_path and file_name variables into a single file path that is platform-independent.
