Scientific Computing with Python Projects - Budget App

carolkboabaid · January 18, 2023, 1:35pm

Hi, guys!

I finished my code from the “Budget App”, but it keeps failing on the last test, which is from the function create_spend_chart.

I already counted all of the blank spaces, but I can not find out what is wrong.

The error which appears is >>> "Perc[77 chars]| \n 60| \n 50| \n [297 chars] t ’ != 'Perc[77 chars]| o \n 60| o \n 50| o \n [297 chars] t ".

My code is:

class Category:
    # Creating the attributes
    def __init__(self, category):
        self.category = category
        self.ledger = list() 
        
    # Printing the category
    def __str__(self):
        first_line = self.category.center(30, "*") 
        middle_line = ''
        total = 0
        for item in self.ledger:
            # Adding the spaces to 'description'             
            if len(item['description']) < 23:
                item['description'] = item['description'].ljust(23)
            else: 
                item['description'] = item['description'][0:23]
            # Adding the spaces to 'amount'
            item['amount'] = "{:.2f}".format(float(item["amount"]))
            if len(item['amount']) < 7:
                item['amount'] = item['amount'].rjust(7)
            else: 
                item['amount'] = item['amount'][0:7]
            middle_line += item['description'] + item['amount'] + '\n'
            total += float(item['amount'])

        if (x != len(maxi) - 1):

        x_axis += nameString
    result += '    ' + dashes  + '\n' + x_axis

Could anyone help me, please?

Compare the expected table:

Per the spec you need to calculate the percentages spent in each category of the total spent. It looks like you are calculating the percent spent of the money in each category.

Thank you!

I fix the problem of the percentage, but it still not passing the test.

The error is >>> AssertionError: 'Perc[34 chars] \n 90| \n 80| \n 70| o[330 chars] t ’ != 'Perc[34 chars] \n 90| \n 80| \n 70| [340 chars] t ’

Check the spacing. This is your current output:
