LaTeX insert code snippet

To insert code snippet in LaTeX you can use the the verbatim environment

\begin{verbatim}
Text enclosed inside \texttt{verbatim} environment 
is printed directly 
and all \LaTeX{} commands are ignored.
\end{verbatim}

To insert a code snippet in LaTeX, you can use the listings package. Here’s an example of how to do it:

1. Add the listings package to your LaTeX document’s preamble:

\usepackage{listings}

2. Define a new environment for your code snippet. You can customize the appearance of the code by specifying different options within the square brackets. For example:

\lstnewenvironment{code}[1][]%
{
  \lstset{#1}
}{}

3. Now, you can use the code environment to insert your code snippet in the document. Specify the programming language using the language option and provide the code within the environment. For example:

\begin{code}[language=Python]
def hello_world():
    print("Hello, World!")

hello_world()
\end{code}

Here’s the complete example:

\documentclass{article}
\usepackage{listings}

\lstnewenvironment{code}[1][]%
{
  \lstset{#1}
}{}

\begin{document}

\begin{code}[language=Python]
def hello_world():
    print("Hello, World!")

hello_world()
\end{code}

\end{document}

This will format the code snippet with syntax highlighting and appropriate indentation based on the specified language. You can modify the options in the lstset command to customize the appearance further.
