What is wrong in here

What error are you getting? Can you link to your repl.it code?

Traceback (most recent call last):
File “/home/runner/boilerplate-budget-app/test_module.py”, line 94, in test_create_spend_chart
self.assertEqual(actual, expected, ‘Expected different chart representation. Check that all spacing is exact.’)
AssertionError: ‘Perc[33 chars] \n 90| \n 80| \n 70| [293 chars] t’ != 'Perc[33 chars] \n 90| \n 80| \n 70| [341 chars] t ’

self.assertEqual(actual, expected, ‘Expected different chart representation. Check that all spacing is exact.’)
AssertionError: ‘Perc[33 chars] \n 90| \n 80| \n 70| [293 chars] t’ != 'Perc[33 chars] \n 90| \n 80| \n 70| [341 chars] t ’
```

The error is telling you that the spacing is not right. Here’s a bit of the expected output from the unit tests (reformatted from the original):

```
" 20| o o \n"
" 10| o o \n"
" 0| o o o \n"
```

Here’s the corresponding output of the tests on your code on my machine:

```
- 20| o
+ 20| o o
? ++
- 10| o o
+ 10| o o
? ++
- 0| o o o
+ 0| o o o
? ++
```

The `-`

lines are your output, the `+`

lines are the expected output, and the `?`

indicate differences. So, your lines are missing some spaces and your columns are all one `o`

short.

Good luck.

draw = map(lambda x:int(`math.ceil(x/10)`

),map(lambda x:reduce(lambda a, b : a+b[‘amount’],
filter(lambda f: f[‘amount’] < 0,x.ledger),0)*100/withdraw,arr))

`expect.append(percentage[i] +" " + " ".join(k[i]) + " ")`

` expect.append(" " * 4 + "---------- ")`
