Tell us what’s happening:
I cannot run or check my code. The code editor keep prompting “Your code raised an error before any tests could run. Please fix it and try again.”
The issue happened even I simply declare an class e.g.
class Category:
____pass
I try other previous exercises and it remains the same 
Your code so far
class Category:
def __init__(self, category_name):
self.category_name = category_name
self.ledger = []
def deposit(self, amount, description=''):
self.ledger.append({'amount': amount, 'description': description})
def withdraw(self, amount, description=''):
canWithdraw = self.check_funds(amount=amount)
if canWithdraw:
self.ledger.append({'amount': - amount, 'description': description})
return True
else:
return False
def get_balance(self):
balance = 0
for transaction in self.ledger:
balance += transaction['amount']
return balance
def transfer(self, amount, destination):
canTransfer = self.check_funds(amount=amount)
if canTransfer:
self.withdraw(amount, f'Transfer to {destination.category_name}')
destination.deposit(amount, f'Transfer from {self.category_name}')
return True
else:
return False
def check_funds(self, amount: int):
balance = 0
for transaction in self.ledger:
balance += transaction['amount']
if amount < balance:
return True
else:
return False
def __str__(self):
balance = 0
print(self.category_name.center(31, '*'))
for transaction in self.ledger:
balance += transaction['amount']
clean_desc = transaction['description'][:23]
print(f'{clean_desc:<23} {transaction['amount']:>7.2f}')
print(f'Total: {balance:.2f}')
def create_spend_chart(categories):
print('Percentage spent by category')
