Strange characters in Python

I am working on Python and experimenting with escape sequences \vand \f. The output seems to give strange characters, where I put these 2 escape sequences. I cannot post an output image due to some anti-spam policies on the website. Can anyone give any ideas as to what might be the problem. Thank.
