Using LaTeX Beamer to display code

Question

I\'m using the following LaTeX code in a Beamer presentation:

\\begin{frame}
  \\begin{figure}
  \\centering
      \\tiny
   \\lstset{language=python}
         \         


        

Answer 1

This has nothing to do with beamer; it's about a listings feature. Its excellent manual has more. For example:

\lstinputlisting[firstline=2,lastline=5]{code/get_extent.py}
