I want to perform an union of these both files such that i get an output
file3.txt which contains:

The program that i'm working on just combines two files. Any help on
performing an union such that a keyword would not be repeated would be
appreciated.
Code:
with open("C:\\File1.txt") as fin1: lines = fin1.readlines()
with open("C:\\File2.txt") as fin2: lines.extend(fin2.readlines())
with open("D:\\file3.txt", "r+") as fout: fout.write('\n'.join(lines))
