**Bad:**

address='One Infinite Loop, Cupertino 95014'

city_zip_code_regex=r'/^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$/'

preg_match($cityZipCodeRegex,$address,$matches);

city_zip_code_regex='^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$'

matches= re.match(city_zip_code_regex,address)

saveCityZipCode($matches[1],$matches[2]);

save_city_zip_code(matches[1], matches[2])

**Not bad**:

It's better, but we are still heavily dependent on regex.

$address = 'One Infinite Loop, Cupertino 95014';

$cityZipCodeRegex = '/^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$/';

preg_match($cityZipCodeRegex, $address, $matches);

address='One Infinite Loop, Cupertino 95014'

city_zip_code_regex='^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$'

matches= re.match(city_zip_code_regex, address)

city, zip_code= matches.groups()

list(, $city, $zipCode) = $matches;

saveCityZipCode($city, $zipCode);

save_city_zip_code(city, zip_code)

**Good**:
