PyCodes.io

Code has been expanded to optionally accept a csv file (currently containing only postcodes and a second column).

• In this case it will scan through the postcodes and return the lat/long for each one.
• This will then be output to a csv file as postcode,latitude,longitude,area

Alternatively, the original function of this script is to compare the output of Postcode API's, currently this is just:

• Postcodes.io
• Doogal
