Tell us what’s happening:
I’ve checked my create_spend_chart function many times, but still, I don’t know why my code fails the last test case. I compared my output with the last test case output and found that categories are only placed differently. What’s the problem with create_spend_chart function? All other functions seem to be alright and pass all the tests. Any help would be greatly appreciated.
Your code so far:
class Category:
instances = []

self.name = name
self.ledger = []
Category.instances.append(self)
def deposit(self, amount, description=""):
self.ledger.append({"amount": amount, "description": description})
def withdraw(self, amount, description=""):
if self.check_funds(amount) is False:
return False
self.ledger.append({"amount": -amount, "description": description})
return True
def get_balance(self):
return sum([item["amount"] for item in self.ledger])
def transfer(self, amount_to_transfer, where_to_transfer):
if self.check_funds(amount_to_transfer) is False:
return False
self.withdraw(amount_to_transfer, f"Transfer to {where_to_transfer.name}")
where_to_transfer.deposit(amount_to_transfer, f"Transfer from {self.name}")
return True
def check_funds(self, amount):
if self.get_balance() >= amount:
return True
else:
return False
def __str__(self):
title = ""
for x in range(15 - (len(self.name)//2)):
title += "*"
title += self.name
for x in range(30 - len(title)):

content += "Total: {:.2f}".format(self.get_balance())
return title + "\n" + content

for instance in instances:

0]))*100//(sum_of_withdraws)

longest_instance_name = 0
for instance in instances:

longest_instance_name = len(instance.name)
updated_names = []
for instance in instances:
while len(instance.name) < longest_instance_name:
