If you already own that lens and a Pentax body, purchasing a used Canon body would probably be the easiest way to put the lens to use. Many, many decent Canon DSLR cameras on the used market.
If you own that lens & a Pentax DSLR and are determined to use the Pentax, you can either 1) trade-in the lens for the same or a similar model with Pentax K-mount; OR 2) sell the lens via EBAY and buy a Pentax K-mount version separately. IF you can sell the lens, that will probably earn you more $$ for it that trading it in.
Thank you all so much for your help!
This is my first experience in a forum and you've all been brilliant!
Thank you again.
