Using a custom environment for a src language

[Rustom Mody]

I have my own Python environment called PYT.
#+BEGIN_PYT
contents
#+END_PYT
generates

\begin{PYT}
org transcoded contents
\end{PYT}

But I dont want org transcoded contents but verbatim contents.

Is there some way to tell org?
1. Translate the headlines as its doing
2. Leave the contents alone

I did try
#+BEGIN_SRC Python :environment PYT
