I have this json object in ajax\_data variable

```
{
    "columns[0][data]": "0", 
    "columns[1][name]": "", 
    "columns[5][searchable]": "true", 
    "columns[5][name]": "", 
    "columns[4][search][regex]": "false", 
    "order[0][dir]": "asc", 
    "length": "10", 
}

```

I have converted it using json.loads() function like.

```
ajax_data = json.loads(ajax_data)

```

I want to get the value if "order[0][dir]" and "columns[0][data]" but if i print it using 

```
ajax_data['order'][0]['dir]

```

its giving error :

```
KeyError at /admin/help
'order'

```

But same code works if i access it for length key then it works.
