Lesson 6. Brownie FUNDME- ERROR cannot import name 'get_account' from 'scripts.helpful_scripts'

After following step by step the lesson I find an error that I cannot solve. I am putting here the entire code.

[tboxtra]

You didn't upload the codes for your helpful-scripts. The get_account() function might be missing

[ellyblueeyes]

The code for helpful_scripts.py

from brownie import network, config, accounts from scripts.helpful_scripts import get_account

def get_account(): if network.show_active()=="development": return accounts[0] else: return accounts.add(config["wallets"]["from_key"])

[tboxtra]

In your scripts.helpful_scripts. You cannot add this line in your input parameters

from scripts.helpful_scripts import get_account

Remove it and let's see if your code works this time.

[ellyblueeyes]

I remove the line and I got the following error: constructor Sequence has incorrect length, expected 1 but got 0

[tboxtra]

I would prefer a screenshot of the error codes
