[Python] I need to reverse this block of codes functionality. Instead of Taking in zip codes...

# importing required libraries
import requests
import simplekml

# defining important variables
kml = simplekml.Kml()
zip_codes = ['20130', '22602', '99123', '12abc', '39654', '20186']

# creating the core function
def get_coords(zip_codes):

url = f"https://api.zippopotam.us/us/{zip_codes}"


response = requests.get(url)

# collecting required information
if response.status_code == 200:
data = response.json()
Places = data['places'][0]

Longitude = Places['longitude']
Latitude = Places['latitude']
City = Places['place name']
State = Places['state']

return Longitude, Latitude, City, State
else:
return f"Error: {response.status_code},could not retrieve data." # filtering out bad inputs

# a for loop to check each specific value in the zip_codes tuple
for codes in zip_codes:
if len(get_coords(codes)) == 4: # if/else solved error that occured when a zip code was not valid
print(get_coords(codes)) # a check to make sure the program is running smoothly
Longitude, Latitude, City, State = get_coords(codes) # unpacks returned tuple from the previous function
Location = [City, State] # repacks city and state variables into the "Location" tuple
kml.newpoint (name = codes, description = Location,
coords = [(Longitude, Latitude)]) # gives the KML file the required data
else:
print(get_coords(codes))

kml.save('GoogleEarth.kml')


Right now, this block takes zip codes and calls zippotam.us to get location data, then converts that information into a KML file. I just need to reverse it, getting the zip code from the location data.

Problem is this is for a class, and my teacher has not been good at teaching beginners (a friend helped me write this code). So I haven't tried anything yet due to not really knowing what to do.
