Help: Searching the region name if it contains a city name in geoname.org JSON files

Hello there, I am using jmespath for python 3.x. I am trying to create a query that would return the array of name attribute of `region` if it contains a specific 'city'. Here is the schema of the JSON.

```
{
country-name
country-code
regions[
{
region-name
region-code
cities[
{city-name, city-lat, city-long},
{city-name, city-lat, city-long},
]
},

{
region-name
region-code
cities[
{city-name, city-lat, city-long},
{city-name, city-lat, city-long},
]
}
]
}
```

Attaching a sample JSON from [Geonames.org](www.geonames.org) for `country=India, city=Rampur`.
