Everything I wrote is correct and even displays correctly yet is still says that the create_spend_chart() function isnt displaying the chart correctly. I dont know why please help me
Your code so far
class Category:
def __init__(self, name):
self.name = name
self.ledger = []
def deposit(self, amount, description=""):
self.ledger.append({"amount": amount, "description": description})
def withdraw(self, amount, description=""):
if self.check_funds(amount):
self.ledger.append({"amount": -amount, "description": description})
return True
return False
def get_balance(self):
return sum(item["amount"] for item in self.ledger)
def transfer(self, amount, category):
if not self.check_funds(amount):
return False
self.withdraw(amount, f"Transfer to {category.name}")
category.deposit(amount, f"Transfer from {self.name}")
return True
def check_funds(self, amount):
return amount <= self.get_balance()
def __str__(self):
title = f"{self.name:*^30}\n"
items = "".join(f"{item['description'][:23]:23}{item['amount']:>7.2f}\n" for item in self.ledger)
total = f"Total: {self.get_balance():.2f}"
return title + items + total
def create_spend_chart(categories):
spent = [sum(-item["amount"] for item in cat.ledger if item["amount"] < 0) for cat in categories]
total_spent = sum(spent)
percentages = [int((amount / total_spent) * 10) * 10 for amount in spent]
chart = "Percentage spent by category\n"
for i in range(100, -1, -10):
chart += f"{i:>3}| " + " ".join("o" if percent >= i else " " for percent in percentages) + " \n"
chart += " " + "-" * (3 * len(categories) + 2) + "\n"
max_len = max(len(cat.name) for cat in categories)
names = [cat.name.ljust(max_len) for cat in categories]
for i in range(max_len):
chart += " " + " ".join(name[i] for name in names) + " \n"
return chart.rstrip()
food = Category("Food")
clothing = Category("Clothing")
entertainment = Category("Entertainment")
food.deposit(1000, "initial deposit")
food.withdraw(10.15, "groceries")
food.withdraw(15.89, "restaurant")
clothing.deposit(500, "initial deposit")
clothing.withdraw(50, "jeans")
entertainment.deposit(300, "initial deposit")
entertainment.withdraw(100, "movies")
print(food)
print(create_spend_chart([food, clothing, entertainment]))

if you take that AssertionError line and put the two compared strings one below the other you should see the difference, yours is the first
for the diff that is below, I have added a description below
The assertion error and diff gives you a lot of information to track down a problem. For example:
AssertionError: 'Year' != 'Years'
- Year
+ Years
? +
Your output comes first, and the output that the test expects is second.
AssertionError: ‘Year’ != ‘Years’
Your output: Year does not equal what’s expected: Years
This is called a diff, and it shows you the differences between two files or blocks of code:
- Year
+ Years
? +
- Dash indicates the incorrect output + Plus shows what it should be ? The Question mark line indicates the place of the character that’s different between the two lines. Here a + is placed under the missing s .
Here’s another example:
E AssertionError: Expected different output when calling "arithmetic_arranger()" with ["3801 - 2", "123 + 49"]
E assert ' 3801 123 \n - 2 + 49 \n------ ----- \n' == ' 3801 123\n- 2 + 49\n------ -----'
E - 3801 123
E + 3801 123
E ? ++++
E - - 2 + 49
E + - 2 + 49
E - ------ -----
E + ------ -----
E ? +++++
The first line is long, and it helps to view it as 2 lines in fixed width characters, so you can compare it character by character:
Again, your output is first and the expected output is second. Here it’s easy to see extra spaces or \n characters.
E - 3801 123
E + 3801 123
E ? ++++
Here the ? line indicates 4 extra spaces at the end of a line using four + symbols. Spaces are a little difficult to see this way, so it’s useful to use both formats together.
Ohhhhh it strips the spaces OKkkkk I Am reallyy sorryy I didnt even notice that I am really sorry for the inconvenience I wrote it out of habit and didnt even realize that it was returning the stripped version I am really sorry and Thanks for your help
