Here’s the code. I don’t know why the result says the spacing is wrong

```
def create_spend_chart(categories):
spending = [round(Category.expense,2) for Category in categories]
heading = "Percentage spent by category\n"
percent_chart = ''
total = round(sum(spending), 2)
percentage_list =[round((((spent/total)*10)//1)*10) for spent in spending]
for number in range(100,-1,-10):
percent_chart += str(number).rjust(3) + '|'
for percentages in percentage_list:
if percentages >= number:
percent_chart += ' o '
else:
percent_chart += ' '
percent_chart += chr(10)
combined = heading + percent_chart
footer = " " + ("-" * ((len(categories)*3) + 1))
the_categories = [x.category for x in categories]
max_length = 0
for x in the_categories:
if len(x) > max_length:
max_length = len(x)
categs = [category.ljust(max_length) for category in the_categories]
for category in zip(*categs):
footer += "\n" + " " + "".join(map(lambda s: s.center(3), category)) + " \n"
return (combined + footer).rstrip()
```

Here’s the error message:
