[Tex/LaTex] Problem with listings package for Python syntax coloring

Question

I am implementing the method I learned here for putting Python code in Latex. Everything works great except that I have problems with comments. Here's the code from the link I mentioned:

\usepackage[utf8]{inputenc}
\DeclareFixedFont{\ttb}{T1}{txtt}{bx}{n}{9} % for bold
\DeclareFixedFont{\ttm}{T1}{txtt}{m}{n}{9}  % for normal
% Defining colors
\usepackage{color}
\definecolor{deepblue}{rgb}{0,0,0.5}
\definecolor{deepred}{rgb}{0.6,0,0}
\definecolor{deepgreen}{rgb}{0,0.5,0}


\usepackage{listings}

% Python style for highlighting
\newcommand\pythonstyle{\lstset{
language=Python,
backgroundcolor=\color{white}
basicstyle=\ttm,
otherkeywords={self},            
keywordstyle=\ttb\color{deepblue},
emph={MyClass,__init__},          
emphstyle=\ttb\color{deepred},    
stringstyle=\color{deepgreen},
commentstyle=\color{red}
frame=tb,                         
showstringspaces=false            
}}

% Python environment
\lstnewenvironment{python}[1][]
{
\pythonstyle
\lstset{#1}
}
{}

I use the following function, python, defined in the code, to generate Python code:

\begin{python}
 class MyClass(Yourclass):
    def __init__(self, my, yours):
        String = "String"
        String2 = '5 1 2 3 4'
        print String2
        import numpy as np #Comment1
        # Comment2
\end{python}

This is the result. I see two frame words for each comment. Do you know what can be wrong here? The link that I mentioned works perfectly in every other aspect. Thanks.

Answer 1

you have some missing comma:

\newcommand\pythonstyle{\lstset{
  language=Python,
  backgroundcolor=\color{white}, %%%%%%%
  basicstyle=\ttm,
  otherkeywords={self},            
  keywordstyle=\ttb\color{deepblue},
  emph={MyClass,__init__},          
  emphstyle=\ttb\color{deepred},    
  stringstyle=\color{deepgreen},
  commentstyle=\color{red},  %%%%%%%%
  frame=tb,                         
  showstringspaces=false            
}}
