Hi folks, maybe someone can help me with the following.
I’m on the Scientific Computing with Python Budget App project. My program has passed all the tests except the chart. However, I’m coming across a problem with the chart in the tests.
Whenever I try to run the test, my chart is made using the print(create_spend_chart([food, clothing, auto])) line in ‘main.py’.
However, the test is looking for a chart created by the line:
actual = create_spend_chart([self.business, self.food, self.entertainment])
My chart is therefore different from the expected result:
Is there a reason why the test would be creating a different chart from the one it expects?
My code:
class Category:
def __init__(self, category):
self.category = category
self.ledger = list()
self.balance = 0
self.total_spend = float()
self.percentage_total = 0
self.percent_points = []
def deposit(self, amount, description = ""):
self.ledger.append({"amount": round(float(amount),2), "description": description})
self.balance = self.balance + amount
def withdraw(self, amount, description = ""):
if self.check_funds(amount) is True:
self.ledger.append({"amount": -1 * round(float(amount),2), "description": description})
self.balance = self.balance - amount
self.total_spend = self.total_spend + amount
return True
else:
return False
def get_balance(self):
return self.balance
def transfer(self, amount, target_cat):
if self.check_funds(amount) is True:
self.withdraw(amount, "Transfer to " + target_cat.category)
target_cat.deposit(amount, "Transfer from " + self.category)
return True
else:
return False
def check_funds(self, amount):
check_amount = amount
if self.balance >= check_amount:
return True
else:
return False
def round_to_ten(self,number):
if number < 10:
return 0
else:
return int(number)
def get_withdrawals(self):
total = 0
for item in self.ledger:
if item["amount"] < 0:
total += item["amount"]
return total
def __str__(self):
ledger_print = """"""
for entry in self.ledger:
ledger_print += str(entry["description"][:23]).ljust(23) + str(format(entry["amount"], '.2f')).rjust(7) + "\n"
return (str(self.category).center(30,"*") + "\n" + ledger_print + 'Total: ' + str(self.balance))
def total_spend(categories):
all_total_spend = float()
# work out total spend
for category in categories:
cat_spend = category.get_withdrawals()
all_total_spend = all_total_spend + cat_spend
return all_total_spend
def cat_percent(categories, all_total_spend):
# % total spend for each category
percent_by_cat = []
for category in categories:
category.percentage_total = (-1 * (category.total_spend / all_total_spend)) * 100
category.percent_points = int(category.percentage_total)
percent_by_cat.append(category.percent_points)
return percent_by_cat
def create_spend_chart(cats):
# works out longest name
name_length = 0
for category in cats:
if len(category.category) > name_length:
name_length = len(category.category)
# setting up output string dimensions
output = ""
num_cats = 0
spaces = 7
for category in cats:
num_cats +=1
spaces += 2
# calculate no of dashes
dashes = ("-" * (spaces-4)).rjust(spaces)
# calculates total spend and percentage per category, puts percentages into dictionary
all_total_spend = total_spend(cats)
percent_by_cat = cat_percent(cats, all_total_spend)
#adds bars to output string
y_axis = 100
cat_spaces = str()
filler = str()
output_line = ""
while y_axis > -1:
filler = list()
lister_iter = 0
for x in percent_by_cat:
if x >= y_axis:
filler.append('{}'.format("o "))
else:
filler.append('{}'.format(" "))
lister_iter += 1
filler_str = "".join(filler)
output += str(y_axis).rjust(3) + "| " + filler_str + "\n"
y_axis -= 10
output += dashes
return output
