[easy][extension][py][hf] add unintended-removed comma (#839)

[easy][extension][py][hf] add unintended-removed comma


comma was mistakenly removed. Adding it back in.

For context: Doesn't break anything because in python you can
concatenate strings without using the + operator by simply placing them
adjacent to each other, like this:

```
"string1" "string2"
```
