Hello, i have a problem with the test unit, I don’t understand why it return that output.

Your code so far

Challenge: Scientific Computing with Python Projects - Budget App

Link to the challenge:

Each item in the ledger should be a dict, with amount and descritption keys. Currently ledger contains list of strings.

In the exercice they say that ledger is a list and not a dict.

Ledger is a list. Each item in ledger is dict (object). It’s a list of dicts, not list of strings.
