I have been working on this for a while and have finally made things work how I want them to work. I realise that my code is super inefficient and this is showing by the really long time it takes to load the data :(
I am using SQL queries to create an array as follows...

key_c = ord(key[i % len(key)])
br_c = ord(c)
decoded +=(chr((br_c - key_c) % 127))
return decoded
def encrypt(key, ar):
encoded = ''
for i in range(len(ar)):
key_c = ord(key[i % len(key)])

I have a bunch of csv files which I have to read and look for data. The csv file is of the format:

Lungfish (also known as salamanderfish) are freshwater fish belonging to the subclass Dipnoi. Lungfish are best known for retaining characteristics primitive within the Osteichthyes, including the ability to breathe air, and structures primitive within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton.
Today, lungfish live only in Africa, South America and Australia. While vicariance would suggest this represents an ancient distribution limited to the Mesozoic supercontinent Gondwana, the fossil record suggests advanced lungfish had a widespread freshwater...
