The challenge is pretty easy, we can already tell from the title and the description that we'll be dealing with google maps. *perhaps*?the enc.txt file contains different latitudes and longitudes. 
The hardest part of this challenge is probably dealing with google maps api.after several attempts I gave up on it and went looking for something else, I ended up using OpenCage API that also offers a python module, Great!
```from opencage.geocoder import OpenCageGeocode
key = ""geocoder = OpenCageGeocode(key=key)
world = eval(open("enc.txt").read())flag = "nactf{"
for place in world:    results = geocoder.reverse_geocode(place[0], place[1])    flag += results[0]["components"]["country"][0]else:    flag+="}"    print(flag)```
