What is the most propriate way to convert this to a dictionary in Python?
plain `json.loads(a)` cannot decipher this format.

This weird JSON string is created when I read a CSV with one "json-like" column. | 2019/10/02 | [

] | I don't know this kind of format for json. So you can use the next function :
```
import json
def load_weird_json(json_string):
a = json_string.replace('""','"')
a = a[1:len(a)-1]
return json.loads(a)
``` | Try
```
import json
a = '"{""key1"": ""val1"", ""key2"":"val2""}"'
a = a.replace('""','"').replace('}"',"}").replace('"{','{')
data = json.loads(a)
print(data)
```
output
```
{'key1': 'val1', 'key2': 'val2'}
