File path in python

Question

I'm trying to load the json file but it gives me an error saying No such file or directory:

with open ('folder1/sub1/sub2/sub2/sub3/file.json') as f:
    data = json.load(f)
print data

The above file main.py is kept outside the folder1. All of this is kept under project folder.

So, the directory structure is Project/folder1/sub1/sub2/sub2/sub3/file.json Where am I going wrong?

Are you using abs path? It is 'folder1/...' but not '/folder1/...' ? And what's your current dir where you execute the main.py — atupal

I omitted the initial slash, but it didnt worked. My main.py file is kept under project folder — Praful Bagai

what's your current dir where you execute the main.py, If it not under the Project, the real path of f if your_current_dir + '/folder1/...' but not Project/folder1/sub1/sub2/sub2/sub3/file.json — atupal

I prefer to point pathes starting from file directory

import os
script_dir = os.path.dirname(__file__)
file_path = os.path.join(script_dir, 'relative/path/to/file.json')
with open(file_path, 'r') as fi:
    pass

this allows not to care about working directory changes. And also this allows to run script from any directory using it's full path.

python script/inner/script.py

or

python script.py

I would use os.path.join method to form the complete path starting from the current directory.

Something like:

json_filepath = os.path.join('.', 'folder1', 'sub1', 'sub2', 'sub3', 'file.json')

As always, an initial slash indicates that the path starts from the root. Omit the initial slash to indicate that it is a relative path.
