python env with dictionary

[maiya]

Hello All,

I want to create an .env file which should contains the dictionary format variables for logging. Later I would like to read those variables through my code.
Below is my

mymodule.env

file

logging = {
    'module1': {
        'path': '/usr/log/module1.log',
        'level': 'DEBUG'
    },
    'module2': {
        'path': '/usr/log/module2.log',
        'level': 'DEBUG'
    },
    'module3': {
        'path': '/usr/log/module3.log',
        'level': 'DEBUG'
    }
}

And at the same I want this variable to enable and disable on the fly. For example, just by enabling this variable (logging) will be activated and it should start logging.

How to read the above env file through my code and reading, how to enable it on the fly.

Thanks for your support.

Regards,
Maiya

I am not too sure what you want to do. I don't know what a .env file is. Your logging variable looks like a .json file.

import json
from pathlib import Path

# don't save in /usr/log, I will use my /home/pedro/temp/ folder
path2json = Path('/home/pedro/temp/log_dict.json')
path2log = Path('/home/pedro/temp/log/')

logging = {
    'module1': {
        'path': '/usr/log/module1.log',
        'level': 'DEBUG'
    },
    'module2': {
        'path': '/usr/log/module2.log',
        'level': 'DEBUG'
    },
    'module3': {
        'path': '/usr/log/module3.log',
        'level': 'DEBUG'
    }
}

# save the logging as json
with open(path2json, 'w', encoding='utf-8') as fp:
    json.dump(logging, fp, ensure_ascii=False, indent=4)

# open the data to inspect it
with open(path2json) as fp:
    data_dict = json.load(fp)
    type(data) # returns <class 'dict'> so we have a Python dictionary

# I won't make files in /usr that could cause problems
# create the log files in /home/pedro/temp/log/
for key in data_dict.keys():
    print(key)
    print(f'path = {data_dict[key]["path"]}')
    logfile = Path(data_dict[key]["path"])
    savename = logfile.name
    savepath = path2log / savename
    with open(savepath, 'a') as sp:
        sp.write(f'This is {logfile}')

# make a list of the files now in path2log
file_list = [filename for filename in path2log.iterdir() if filename.is_file()]

for filename in file_list:
    print(filename)

Now I have 3 log files in /home/pedro/temp/log/:

Output:
/home/pedro/temp/log/module1.log
/home/pedro/temp/log/module3.log
/home/pedro/temp/log/module2.log

Maybe that is something like what you want?
