[|Human|] Identify the faults in this program and suggest a fix.
[|AI|] The program contains an indentation error. The keyword "return" should be indented at the same level as the code within the function in order for it to be part of the function. The corrected version would look like this:

```
def my_function(x):
    x += 10
    return x
```
