checking username

[Pedroski55]

They should have written usernames, that would be less confusing for you perhaps.

Try like this maybe? Make your own file, then save it and then open it.

Of course, you need to set your own path, don't try to use my path!

import json
from pathlib import Path

path2json = '/home/pedro/temp/usernames.json'
mypath = Path(path2json)
data = []
username = 'X'
# enter usernames and emails
while not username == 'q':
    users_dict = {}
    username = input(f'Enter your username, enter q to quit ... ')
    if username == 'q':
            break
    email = input('enter your email ... ')
    users_dict['user name'] = username
    users_dict['user email'] = email
    data.append(users_dict)

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

# open the data to inspect it
with open(mypath) as fp:
    data_list = json.load(fp)

# find Tarzan
for d in data_list:
    if d['user name'] == 'Tarzan':
        print(d)
        print(d['user name'])

Output:
{'user name': 'Tarzan', 'user email': '[email protected]'}
Tarzan
