I much prefer Python's implicit line continuation within a set of parentheses. For example:
```python
url = (settings.ANALYTICS_SERVER_URL + 
        "get?aname={}&course_id={}&apikey={}".format(analytics_name,
                                                     course_id,
                                                     settings.ANALYTICS_API_KEY)
)
```
Because all of that is in one set of parentheses, you don't need the backslash. And no, it won't be interpreted as a tuple: Python only converts the contents of parentheses into a tuple if there's a comma in there. For example, a 2-tuple is `("a", "b")` and a 1-tuple is `("a",)`, but this is not a tuple: `("a")`
