Tell us what’s happening:
I have almost done the project so far. The last thing that I can’t manage to pass the test is the barchart, and I suppose I have a spacing problem because the bar returned seems exactly like the examples. I have been looking where I have the wrong formattinc but I can’t find it and my eyes already hurt looking where I need to add (or remove) spaces.
I appreciate any help in advance!
Your code so far
class Category:
def __init__(self, name):
self.name = name
self.ledger = []
# returns balance of category based on deposits and withdrawals
def get_balance(self):
prices = []
for i in self.ledger:
prices.append(i["amount"])
balance_total = sum(prices)
return balance_total
# This must be used by withdraw and transfer.
# Accepts an amount as an argument
# Returns False if amount less than balance of budget and True otherwise
def check_funds(self, amount):
if amount <= self.get_balance():
return True
else:
return False
# Add an amount and description to the category:
def deposit(self, amount, description = ""):
deposit_dict = {"amount": amount, "description": description}
self.ledger.append(deposit_dict)
# have to add a dictionary ONLY if there are enough funds
# if no funds, return False. If funds, do the operation and return True:
def withdraw(self, amount, description = ""):
if self.check_funds(amount) == True:
withdraw_dict = {"amount": -amount, "description": description}
self.ledger.append(withdraw_dict)
return True
else:
return False
# put an amount and name of another budget.
# add a withdrawal with amount and the description "Transfer to [Destination Budget Category]"
# add a deposit with amount and description "Transfer from [Source Budget Category]"
# IF no funds, cancel previous 2 steps. return True if transfer Ok, if not, returns False
# 5
def transfer(self, amount, destination):
if self.check_funds(amount) == True:
self.withdraw(amount, description = "Transfer to " + destination.name)
destination.deposit(amount, description = "Transfer from " + self.name)

# To be printed:
def __str__(self):
# title with 30 characters and name centered, filled with "*":
table = self.name.center(30,"*") + "\n"
for i in self.ledger:

def create_spend_chart(categories):
names = []

percent_spent = []
sum_spent = 0
for i in categories:

# Get total withdraw values from each category in a list:

# Get percentages spent in a list, by categories:

# Rounded to 2 decimals in percent:
percent_spent.append(round(i / sum_spent, 2) * 100)
# Now we can go to create the bar chart:
bar_chart = "Percentage spent by category" + "\n"
# Create a counter to have from 100 to 0:
counter = 100
# With this we have the layout of the bar:
while counter >= 0:
# Added align to right with width 4 to adjust the percentages:
bar_chart += (str(counter) + "|").rjust(4)
# If the percentage is greater or equal than the counter, add a bar:
for i in percent_spent:
if i >= counter:
bar_chart += " o "
# If the percentage is lesser than the counter, add only spaces:
else:
bar_chart += " "
# Substract then 10 to the counter to keep writing the bar:
counter -= 10
# And start the next iteration of the loop in a new line:
bar_chart += "\n"
# Add necessary spaces in the horizontal line, and depending on the number of
# categories, enlarge the line. Also we add a newline and the respective spaces
# to align correctly the posterior names:
bar_chart += " " + "---" * len(percent_spent) + "-" + "\n" + " "
# Check the number of letters of the longest category name:
longest_name = 0
for i in names:
if len(i) > longest_name:
longest_name = len(i)
# Loop through each letter of each category in one line:
for i in range(longest_name):
for j in names:
if len(j) > i:
bar_chart += " " + j[i] + " "
else:
bar_chart += " "
if i < longest_name - 1:
bar_chart += "\n "
# Return the string containing the bar chart
return bar_chart
