Create a new function that will return a variable named rankings, which is a list of dictionaries set up as follows:

rankings $[$i$]$ is a dictionary corresponding to the restaurant whose rank is $i+1.$ For example, from the screenshot above, rankings $[0]$ should be a

dictionary with information about Gus's World Famous Fried Chicken.

Each dictionary, rankings $[$i$],$ should have these keys:

rankings $[$i$][\text{'}$name $\text{'}]$: The name of the restaurant, a string.

rankings$[$i$][\text{'}$stars$\text{'}]$: The star rating, as a string, e$.$g$.,\text{'}4\mathrm{.}5\text{'},\text{'}4\mathrm{.}0\text{'}$

rankings $[$i$][\text{'}$numrevs$\text{'}]$: The number of reviews, as an integer.

rankings $[$i$][\text{'}$price $\text{'}]$: The price range, as dollar signs, e$.$g$.,\text{'}$$$\text{'},\text{'}$$$$\text{'},\text{'}$$$$$\text{'},$ or $\text{'}$$$$$$\text{'}.$

Of course, since the current topic is regular expressions, you might try to apply them $($possibly combined with other string manipulation methods$)$ find the

particular patterns that yield the desired information.

In $[4]$:
