FileNotFoundError: [Errno 2] No such file or directory: error

Question

I'm looping through many folders to get any JSON file in each folder using the following code:

def get_all_jobs():
    for root_dir, _, file_names in os.walk(r'path'):
        for file_name in file_names:
            if file_name.endswith('.json'):
                all_files = (f'{root_dir}/{file_name}')
                for file in all_files:
                    with open(file_name, 'r', encoding="utf8") as json_file:
                        read_content = json.loads(json_file.read())

and I get this error :

FileNotFoundError: [Errno 2] No such file or directory:

and don't have one path to one folder to give but I have many folders in which I have the files. How can I solve this?

Answer 1

find the information about glob here . glob will escape all the inside directories and match our pattern recursively.

def get_all_jobs():    
    for json_file in glob.iglob(path+"/**/*.json".replace('/',os.path.sep),recursive=True):
        with open(json_file, 'r', encoding="utf8") as jf:
            read_content = json.loads(jf.read())

Note: here path is the base directory where you have multiple folders which has your json files.

Explanation :

Here glob goes to your base directory path , from there recursively it goes to all sub folders and checks if any file contains .json extension, If it has, then it gives complete path of that file.
