Best way to convert json to dict in function python? Need help! or How to properly handle json to dic

For json to dict in function python, don’t forget to check if the input is *actually* a string.

Sometimes people pass bytes or other types.

```python
def json_to_dict(json_str):
if isinstance(json_str, bytes):
json_str = json_str.decode('utf-8')
return json.loads(json_str)
```

Saved me a few headaches!
