Libraries
address_helpers.py
Address Helpers. This library is used to interact with address strings/dicts and convert/handle these addresses.
Functions:
def convert_string_address_to_dict(address_string, expected_fields=None):
"""
Purpose:
Parse a string into an address dict with specific fields
Args:
address_string (String): Raw address string to try and parse
expected_fields (List): List of fields that are needed to be parsed to be
considered successful
Return:
parsed_address (Dict): Dict of the parsed address with fields that could be
determined from a string
"""

def parse_address_using_lib_usaddress(address_string):
"""
Purpose:
Use the usaddress library to parse a string into a dict
Args:
address_string (String): Raw address string to try and parse
Return:
parsed_address (Dict): Dict of the parsed address with fields that could be
determined from a string
"""

def parse_address_using_lib_streetaddress(address_string):
"""
Purpose:
Use the street-address library to parse a string into a dict
Args:
address_string (String): Raw address string to try and parse
Return:
parsed_address (Dict): Dict of the parsed address with fields that could be
determined from a string
"""

mapquest_helpers.py
Mapquest Helpers. This library is used to wrap mapquest API calls and handle authentication
Functions:
def get_mapquest_api_key(public_key_file="~/.mapquest/public_key.txt"):
"""
Purpose:
Get the mapquest API from the environment
Args:
public_key_file (String): filename of the public key token file
Return:
mapquest_api_key (String): MapQuest public key
"""

def get_directions_between_two_addresses(mapquest_api_key, address_1, address_2):
"""
Purpose:
Get directions between two addresses

Leverages Mapquest API:
https://developer.mapquest.com/documentation/directions-api/route/get/
Args:
address_1 (String): Address to use as start point of travel
address_2 (String): Address to use as end destination of travel
Return:
directions (Dict): Dict of the directions between the two locations
"""

Example Scripts
Example executable Python scripts/modules for testing and interacting with the library. These show example use-cases for the libraries and can be used as templates for developing with the libraries or to use as one-off development efforts.
parse_addresses.py
Purpose:
Parse some set addresses

Steps:
- Parse Args
- Call libs to parse addresses

function call:
python3.6 parse_addresses \
[-h] \
--addresses ADDRESSES

example script call:
python3.6 example_usage/parse_addresses.py \
--address="REDACTED" \
--address="REDACTED"

get_directions_between_addresses.py
Purpose:
Get Directions between two addresses.

Steps:
- Parse Args
- Call libs to get directions from args
- Parse directions for some valuable information

function call:
python3.6 get_directions_between_addresses.py \
[-h] \
--start-address START_ADDRESS \
--end-address END_ADDRESS

example script call:
python3.6 example_usage/get_directions_between_addresses.py \
--start-address="REDACTED" \
--end-address="REDACTED"

Notes

Relies on f-string notation, which is limited to Python3.6. A refactor to remove these could allow for development with Python3.0.x through 3.5.x

TODO

Unittest framework in place, but lacking tests
