Delete key/value from a dictionary Json – Telegram API

In a simple Telegram bot with Telebot I have a dictionary in json format (parole.json). I’m trying a function that allows me to delete an entry (key value pair) from the dictionary and I used this code example found right on this forum:

import json

with open("parole.json", "r") as json_file:
    Dizio = json.load(json_file)

@bot.message_handler(commands=['cut'])
def removeKey(message):
    parola = extract_arg(message.text.lower())

    res = Dizio.get(message.text.lower(), parola)
    trova = str(parola)

    with open("parole.json", "r") as f:
        data = json.load(f)

    if trova in data:
        del data[trova]

    with open("parole.json", "w") as f:
        json.dump(data, f)

    Have you read this question? It’s basically the same question and the answer is already given.

    You need to iterate over the keys by using a for loop that checks if the input == ['key']['value']

    Also, your indenting is incorrect in your removekey(message) function:

    def removeKey(message):
    parola = extract_arg(message.text.lower())
    res = Dizio.get(message.text.lower(), parola)
    trova = str(parola)

    with open("parole.json", "r") as f:
        data = json.load(f)

    if trova in data:
        del data[trova]

    with open("parole.json", "w") as f:
        json.dump(data, f)

    Edit: I see that the indentation was edited just now

    if trova in data:
    del data[trova]

    Calling dict.__del__ removes the key/value pair, so if your file is unchanged it’s because the flow never enters the if statement.

    Maybe it would work with

    if trova in data.keys():

    but I’m not sure if it makes any difference.
