Question:
Can someone help me fix my problem for the getting of JSON data.

Traceback (most recent call last):
  File “main.py”, line 11, in <module>
    keyVal = passwordHolder[‘name’][username]
KeyError: ‘SalladShooter’

import json
import extrapy as e

import os
username = os.environ['REPL_OWNER']

passwordHolder = {}

passwordHolder['name'] = {"name": username}

keyVal = passwordHolder['name'][username]

while True:
  if keyVal in passwordHolder['name']:

    f = open('mydata.json')
    passwordHolder = json.load(f)
    
    print("[1] Add Password")
    print("[2] Show Password")
    print("[3] Stop")
    addPassword = input()
    
    if addPassword == "1":
      e.clear()
      print("Enter Password:")
      password = input()
      passwordHolder['name':username]['password'] = {"password": password}
      e.clear()
      
    
    if addPassword == "2":
      if passwordHolder['name':username]['password'] != "":
        e.clear()
        print(passwordHolder['name':username]['password'])
      else:
        e.clear()
        print("You Do Not Have A Password")
      
    with open('mydata.json', 'w') as f:
      json.dump(passwordHolder, f)
  
    if addPassword == "3":
      e.clear()
      f.close()
      break
  else:
    print('Invalid User')
    break

Here is your updated code:

import json
import extrapy as e

import os
username = os.environ['REPL_OWNER']

passwordHolder = {}

passwordHolder[username] = {
  "password": "..."
}

keyVal = passwordHolder[username]

while True:
  if keyVal in passwordHolder:

    f = open('mydata.json')
    passwordHolder = json.load(f)
    
    print("[1] Add Password")
    print("[2] Show Password")
    print("[3] Stop")
    addPassword = input()
    
    if addPassword == "1":
      e.clear()
      print("Enter Password:")
      password = input()
      passwordHolder[username]['password'] = password
      e.clear()
      
    
    if addPassword == "2":
      if passwordHolder[username]['password'] != "":
        e.clear()
        print(passwordHolder[username]['password'])
      else:
        e.clear()
        print("You Do Not Have A Password")
      
    with open('mydata.json', 'w') as f:
      json.dump(passwordHolder, f)
  
    if addPassword == "3":
      e.clear()
      f.close()
      break
  else:
    print('Invalid User')
    break

The code doesn’t work, unhasable type: dict.

Please tell me the exact error and traceback you’re getting.

Hi, this is happening because the structure of the dict is actually:

{
  "name": {"name": "SaladShooter"}
}

So as per the line: keyVal = passwordHolder['name'][username] that errors:
keyVal = passwordHolder['name'] returns {"name": "SaladShooter"}
Here, in this intermediate dict, the key “SaladShooter” does not exist. So there is a KeyError at line 11

Also further this line passwordHolder['name':username]['password'] will also error out since you cannot slice a dictionary. You can only get keys using the syntax dict["key"]

Fixed code:

Im using this dict structure since i am not sure what you were using:
{ "user1": "pass1", "user2": "pass2" ... }

import json
import extrapy as e

import os
username = os.environ['REPL_OWNER']

passwordHolder = {}

passwordHolder[username] = ""

while True:
  if username in passwordHolder:

    f = open('mydata.json')
    passwordHolder = json.load(f)
    
    print("[1] Add Password")
    print("[2] Show Password")
    print("[3] Stop")
    addPassword = input()
    
    if addPassword == "1":
      e.clear()
      print("Enter Password:")
      password = input()
      passwordHolder[username] = password
      e.clear()
      
    
    if addPassword == "2":
      if passwordHolder[username] != "":
        e.clear()
        print(passwordHolder[username])
      else:
        e.clear()
        print("You Do Not Have A Password")
      
    with open('mydata.json', 'w') as f:
      json.dump(passwordHolder, f)
  
    if addPassword == "3":
      e.clear()
      f.close()
      break
  else:
    print('Invalid User')
    break
