DNS over HTTPS resolver for Python using Google DNS

Requirements
Python 3.4+
Requests library (https://2.python-requests.org/en/master/)

How to use
If you just want a quick A record, use the convenience method:

import dnsOverHttps
try:
  aRecord = dnsOverHttps.GoogleDNSQuery.getARecordFor("google.com")
  print(aRecord) # IP Address here!
except Exception as e:
  print("EXCEPTION - {} - {}".format(type(e),e))

If you just want a quick AAAA record, use the convenience method:

import dnsOverHttps
try:
  aaaaRecord = dnsOverHttps.GoogleDNSQuery.getAAAARecordFor("google.com")
  print(aaaaRecord) # IP Address here!
except Exception as e:
  print("EXCEPTION - {} - {}".format(type(e),e))

If you want more control, or if you want MX or TXT records, create an instance of GoogleDNSQuery with the domain name and record type (a or aaaa, mx or txt) in the constructor, and call query() method. This will return a list of DNSRecord objects you can iterate through in case there's more than 1 of that record type.

query = "google.com"
gd = dnsOverHttps.GoogleDNSQuery(query,"a")

try:
    dnsresponse = gd.query() # List of DNSResponse objects
    for i in dnsresponse: # iterate through them
        print("Record type is {} and record data is {}".format(i.recordType, i.recordData)) # 
except Exception as e:
    print("EXCEPTION: {} - {}".format(type(e), e))

Example
See and run example.py, example-MX.py and example-TXT.py

Limitations
Only a, aaaa, mx and txt records supported at the moment - more to come!

For mx records, ordering by priority is not guaranteed - if you need a specific order then sort the returned list yourself - in example-MX.py there is an example of how to do this.
