Google API directions extractor. I have a need to export Google turn directions into a structured format so that they can be presented as printouts. Google Python reference is here: https://googlemaps.github.io/google-maps-services-python/docs/. Google's github for the python lib - https://github.com/googlemaps/google-maps-services-python which …

import csv
from googlemaps import Client

mapService = Client(key='')

directions = mapService.directions('start','end',waypoints'one|two|three')
directions = directions[0]

i=1
f = open('directions4.csv', 'w')
writer = csv.writer(f,delimiter='+')

for leg in directions['legs']:
      startAddress = leg['start_address']
      print "======================================================================"
      print "Start Address:", startAddress
      endAddress = leg['end_address']
      print "End Address", endAddress
      writer.writerow([''])
      writer.writerow([startAddress+' to '+endAddress])
      for step in leg['steps']:
          html_instructions = step['html_instructions']
# simple regex to remove html tags plus need to sort out encoding
          instructions=re.sub('<[^<]+?>', '',html_instructions ).encode('utf-8')
#         distance = step['distance']['text']
# for distance and time, we only want the numbers, not the units or other text:
          meters = step['distance']['value']
          distance= '{:.4f}'.format(meters/float(1609))
# couldn't work out the time unit used in the api, but its ok to take the string and split it:
          time = step['duration']['text'].split(' ',1)[0]
# not all directions have a maneuver command, but they are useful:
          maneuver = ''
          if step.has_key('maneuver'):
                maneuver = step['maneuver'].replace('turn-','').upper()
          print "STEP {} {} {} {} {}".format(i, maneuver, instructions, distance, time)
          writer.writerow([i,maneuver, instructions, distance, time])
          i = i+1
