We have made a few examples of code in Python and inserted them into a LaTeX/overleaf document. We are currently looking into making a label for them, so they can be referenced at various points, however using the \begin(python) doesn't seem to allow us to add a \label{}, which works and can be referenced.
A similar example of what we are looking for would be
\documentclass[11pt,a4paper,twoside,openany,english]{book}
\usepackage{pythonhighlight}
\begin{python}\label{SO-test}
value_a = 1
value_b = 2
print(value_a + value_b)
\end{python}
Any tips or tricks are appreciated.
Behind the scenes the pythonhighlight uses the much more common listings package. The listings package allows you to add a caption and label as optional argument of the lstlistings environment.
However even though the pythonhighlight sets up its python environment with the possibility to add an optional argument, it never uses this argument. Thus the information is never forwarded to the lstlistings environment.
To work around this, you can set up your own environment:
\documentclass[11pt,a4paper,twoside,openany,english]{book}
\usepackage{pythonhighlight}
\lstnewenvironment{mypython}[1][]{\lstset{style=mypython,#1}}{}
\begin{document}
\begin{mypython}[caption={some text to produce a caption},label=SO-test]
value_a = 1
value_b = 2
print(value_a + value_b)
\end{mypython}
Reference: \ref{SO-test}
\end{document}
I tried to just include this in a comment, but I'm too new to stack overflow.
Have you tried just using regular verbatim instead of making it explicitly python? Is there something wrong with that?
\begin{verbatim}
Text enclosed inside \texttt{verbatim} environment
is printed directly
and all \LaTeX{} commands are ignored.
\end{verbatim}
I also saw this thing about minted in their library.
It makes a reference to \begin{minted}{python}

How can i highlit text in latex.
Thank you.
As is pictured here(in red circle):
If you mean making the text bold by Highlighting you can use \textbf for making the text bold but highlighting has a different general meaning that is implemented by \hl keyword.
\documentclass{report}
\usepackage{color} % for the command \textcolor
\usepackage{soul} % for the command \hl
\begin{document}
\hl{foo}
\hl{\textbf{foo}}
{my garden }
\textbf{black}{foo}
{my good job}
\textbf{\textcolor{red}{\hl{foo}}}
\textcolor{red}{\textbf{\hl{foo}}}
\end{document}
this is the result :
As you can see the word "black" is highlighted the way you desired.
The word "foo" is highlighted in the general meaning of highlighting.
This links look useful:
Insert symbols inside verbatim mode LaTeX
Putting math inside a verbatim environment without altering the formatting
If you just wanted graph.exe I would suggest using \begin{verbatim} graph.exe \end{verbatim} or \verb+graph.exe+ .
However you want to use the <..> expression which can be created with $ \langle ... \rangle $ . The $..$ indicates inline math mode. Those two links discuss getting verbatim text in math environments.
I think tex.stackexchange.com will be more helpful rather than stack overflow.

I want to keep all the symbols in my following text in LaTeX. but I don't know which syntax I should use to keep them. Can anybody give a suggestion?
/forest # search for forest
/<\/way> # find the tag </way>
v # start the visual mode
?<way # find the begin of the tag -> mark <way> until </way>
D # delete that tag
Just put them in verbatim environment, like this:
\begin{verbatim}
...
things you want to keep them as is
...
\end{verbatim}
For inline mode, you can use \verb command:
\verb=...things you want to keep them as is...=
Check out here for more info:
[...] If you use the verbatim environment, everything input between the begin and end commands are processed as if by a typewriter. All spaces and new lines are reproduced as given, and the text is displayed in an appropriate fixed-width font. Any LaTeX command will be ignored and handled as plain text. This is ideal for typesetting program source code. [...]

I include a figure like this
\begin{figure*}
\begin{center}
\includegraphics[width=6.7in]{pic/recall_details.png}
\caption{ Recalls of test query MB002-MB049}
\label{ recall_details}
\end{center}
\end{figure*}
And then I refer it using \ref{recall_details}. Instead of getting numbers like 1, 2, I get ??. Literally I mean ??. What is wrong with my codes? How to make the references show correctly?
You should "compile" your latex code twice to get numbers instead of question marks
The issue is that you're referencing \ref{recalls_details}, but you've defined \label{ recalls_details}. That extra space before recalls_details is what gets you ?? instead of the figure number. You should either change the \ref to \ref{ recalls_details} or the \label to \label{recalls_details}.
On another note, I suggest you add a modifier at the start of the label, such as fig: in this case: \label{fig:recalls_details}. This is useful when you have different types of labels (e.g. to sections, sec:, and to equations, eqn:).
The bottom line is to always use the exact string you give within the \label{} in the relevant \ref{}.

In my report, I'm writing some class names or variable names inside of a paragraph, and I want these names to be rendered in a monospace font.
Example:
This is my class name: \texttt{baseAdminConfiguration}.
Sometimes when the single word inside of the \texttt tag is rendered at the end of a line, the word does not go to the next line, and there is no break in it neither: the end of the word passes over the margin.
How should I handle such a case?
Cheers.
This hasn’t got much to do with \texttt. The word is simply too long, and LaTeX doesn’t know how to hyphenate it. You can tell it how to do this manually, by declaring hyphenation rules:
\hyphenation{base-Admin-Configuration}
The \hyphenation command may take arbitrarily many words, separated by whitespace.
Alternatively, if this doesn’t the trick, you can introduce manual hypenation hints in the text:
This is a long text that uses the word \texttt{base\-Admin\-Configuration) …
Only the actual hyphenation will be displayed – unused so-called discretionary hyphens (\-) will not be displayed so you can freely sprinkle your text with them, if necessary.
[Read more about hyphenation in LaTeX]
To prevent LaTeX from overflowing lines in principle, the whole paragraph can be wrapped in a sloppypar environment (thanks to Will for pointing this out in the comments):
\begin{sloppypar}
Some text …
\end{sloppypar}
This manipulates the parameters of the line-breaking algorithm (in particular, \tolerance). The downside: this can lead to very ugly spacing. Alternatively, \tolerance and other internal parameters can be manipulated directly – the TeX FAQ shows how.
The solution is quite simple: use the url package and replace the texttt command with the path command.
I found out that here
https://tex.stackexchange.com/questions/299/how-to-get-long-texttt-sections-to-break
in the post of Will Robertson.

I'm trying to display a caret (^) in math mode in LaTeX to represent the exclusive or operation implemented in the "C languages". By default, ^ is for creating a superscript in math mode. The closest I can seem to get is by using \wedge, which isn't the same.
You might want to use the common symbol for exclusive or instead, \oplus (but give it a proper name with something like \newcommand\XOR{\oplus}).
The caret is a bit too small to be noticeable as a binary operator. However, if you do insist using a caret instead, use this:
\newcommand\XOR{\mathbin{\char`\^}}
$x \XOR y$
The \mathbin puts the right spacing around the symbol for a binary operator, and the \char ensures that the glyph is obtained from the roman font.
Use the wedge symbol as a superscript. It has the perfect size.
Something like this:
$ ^\wedge $
How about
\^{}
or
\verb|^|
?
Use \textasciicircum in text mode. If you are in math mode, you need to use something like $\mbox{\textasciicircum}$.
This is what I did:
$2\hat{\text{ }}3$
Within math mode, you can use:
$7 \^{ } 3 = 4$
to do this, as shown from the online LaTeX renderer here.
\^ is an accent character that applies to other characters, \^{4} gives a 4 with a carat on its head. It takes up no horizontal space. If you write $7 \^{} 3 = 4$ you get a 73 with a mark smashed onto both the 7 and the 3. What you need then is to fill out the space a little bit. Through trial and error and a nice application called LatexIt, I found this sequence to work beautifully:
\hspace{1.5} \^{} \hspace{1.5}
This gives a 3 unit width with the carat centered in it. It looks nice.
It is a pointy carat though, and \verb|^| gives a more flattened one that looks more like a monotype font frequently used in programming languages.
