Output: I want values delimited with ^A, only with values e.g.:

TLSv1.2 ^A ECDHE-RSA-AES256-GCM-SHA384 ^A PATCH ^A /portal/cache/num_active_capione_nodes ^A 9 ^A 200 ^A 10.202.30.123 ^A [e-mail] ^A 12

Answer

This should do it:

with open("foo.dat", "r+") as f:
    data = f.read()
    data = ata.replace('|', ' ^A ')
    f.seek(0)
    f.write(data)
