Why do two if comparison statements overlap?

Question

Python

@bot.command()
async def M1(message):
    with open('coins.json', 'r') as f:
        users = json.load(f)

    await update_data(users, message.author)
    await start(users, message.author, message)

async def start(users, user, message):
    if users[str(user.id)]['coins'] > 3065000:
        await update_data(users, message.author)
        await delete_coins(users, message.author, 3065000)        
        await send(message)
    else:
        await message.channel.send('Недостаточно средств для покупки.')

    with open('coins.json','w') as f:
        json.dump(users, f)

async def update_data(users, user):
    if not str(user.id) in users:
        users[str(user.id)] = {}
        users[str(user.id)]['coins'] = 0

async def delete_coins(users, user, coin):
    users[str(user.id)]['coins'] -= coin

async def send(message):
    await message.channel.send(f'Да')  

@bot.command()
async def M2(message):
    with open('coins.json', 'r') as f:
        users = json.load(f)

    await update_data(users, message.author)
    await start(users, message.author, message)

async def start(users, user, message):
    if users[str(user.id)]['coins'] > 2065000:
        await update_data(users, message.author)
        await delete_coins(users, message.author, 2065000)        
        await send(message)
    else:
        await message.channel.send('Недостаточно средств для покупки')

    with open('coins.json','w') as f:
        json.dump(users, f)

async def update_data(users, user):
    if not str(user.id) in users:
        users[str(user.id)] = {}
        users[str(user.id)]['coins'] = 0

async def delete_coins(users, user, coin):
    users[str(user.id)]['coins'] -= coin

async def send(message):
    await message.channel.send(f'Да2')

Separately, the commands work correctly, but if they are placed in one code, then the M1 command will issue the values ​​of the M2 command, namely, subtract the number 2065000 and Yes2, with the M2 command it will return everything from the M2 command. Why is that?

Answer 1

Doesn't it bother you that your functions are simply duplicated? Linter not highlighting?
You have two start functions, two update date, etc.
