A little issue with Budget App Project

Python
1

Hello there! So after finishing my project on Replit, I get an error feedback (down below).
But before that, here’s how I wrote my create_spend_chart() function:

def create_spend_chart(categories):
    
    total_withdrawals = sum(category.get_withdrawals() for category in categories)
    
    percentages = []
    for category in categories:
        percentage = (category.get_withdrawals() / total_withdrawals) * 100
        percentages.append(percentage)

    # creating chart 
    chart = 'Percentage spent by category\n'
    
    for num in reversed(range(0, 110, 10)):
        chart += str(num).rjust(3) + '|'
        for category, percentage in zip(categories, percentages):
            if num <=  percentage:
                chart += " o "
            else:
                chart += "  "
        chart += '\n'
    chart += (' ' * 4) + ("---" * len(categories)) + '-' + '\n'
    
    # printing out the names vertically
    max_name_length = max(len(category.category) for category in categories)

    chart += ' ' * 2 # Add initial spacing before the vertical names

    for i in range(max_name_length):
        chart += ' ' * 2  # Add spacing between the vertical names and the chart bars
        for category in categories:
            if i < len(category.category):
                chart +=  ' ' + category.category[i] + ' '   # Adjust the spacing between the characters
            else:
                chart += '   '  # Add empty spaces when the category name is shorter
        chart += '\n' + (' ' * 2)  # Move to the next line after printing all the characters
        
    return chart

And the console returned this error( Even though the output is physically identical to the expected output):

Can anyone please tell me what the issue is?
(I suspect I’m not writing the function the way they want me to, but what I wrote works physically, but ended up producing more characters than expected. Please share your opinion)

In the test output:

  • lines starting with - are actual lines returned by function
  • lines starting with + are expected by the test
  • lines starting with ? indicate the specific places in line, where difference occurs

I think I get it now. Thanks for the explanation. I’ll check it again and see if it works
