hi! my create_spend_chart() function is failing the test because of the spaces, but I don’t seem to find the problem. I’d be grateful if you could help me find it, here’s the code:

```
def create_spend_chart(categories):
output = ['Percentage spent by category']
percentage = []
category = []
numbers = list(range(100,-1,-10))
for budget in categories:
total = sum([x['amount'] for x in budget.ledger if x['amount']>0])
spent = sum([x['amount'] for x in budget.ledger if x['amount']<0])
percentage.append(round((spent*-1)/total * 100))
category.append(budget.name)
for i in range(len(numbers)):
output.append("{:3d}|".format(numbers[i]))
for x in percentage:
if x >= numbers[i]-5:
check = 'o'
else:
check = ''
output[i+1] += "{:^3}".format(check)
output.append(' '+('-'*(3*len(category)+1)))
longest = max(category,key=len)
for i in range(len(longest)):
output.append(' ')
for j in range(len(category)):
if len(category[j])> i:
output[-1] += ' '+category[j][i]+' '
else:
output[-1] += ' '
result = '\n'.join(output)
return result
```

it also says the diff is 1232 characters long.
