|
Get the "salary" of "Pete" from this JSON structure:
|
|
```json
|
|
{
|
|
"users": {
|
|
"Pete": {
|
|
"salary": 10.0

|
}
|
|

|
}
|
|
```
|
|
|
|
This can be easily done with the following code:
|
|
```python
|
|
import libbot
|
|
salary = libbot.sync.config_get("salary", "users", "Pete")
|
|
```
