Thanks all i have solved this... code should be:

fin = open("input.txt")
fout = open("output.txt", "w+")
delete_list = ['https://', 'http://', 'www.']
for line in fin:
    for word in delete_list:
        line = line.replace(word, "")
    fout.write(line)
fin.close()
fout.close()
print './ done'

This took my file into a worser condition that it was earlier. THIS APPROACH IS DANGEROUS. – Pragyaditya Das Sep 17 '16 at 08:41
