"and" in algorithm

Question

So I'm not experienced with the algorithm packages in LaTeX. I'm assuming there must be a way to do

if condition1 and condition2 then...

but I can't find it. I've checked what I can find of the documentation. If I compile the below I get an error for undefined command at the \And. It looks like there is something in algorithm, using \AND, but that doesn't work here and I don't really understand what's going on.

\documentclass{article}
\usepackage[noend]{algpseudocode}
\usepackage[nothing]{algorithm}
\algrenewcommand{\algorithmicrequire}{\textbf{Input:}}
\algrenewcommand{\algorithmicensure}{\textbf{Output:}}

\begin{document}

\begin{figure}
\begin{algorithmic}
\If{$x> y$ \And $ x<z$}
\State{some code here}
\EndIf
\end{algorithmic}
\end{figure}
\end{document}

Is there a way to do what I'm after?

I could not find a \And command but we can make one:

\algnewcommand\And{\textbf{and}}

and add some space...

\documentclass{article}
\usepackage[noend]{algpseudocode}
\usepackage[nothing]{algorithm}
\algrenewcommand{\algorithmicrequire}{\textbf{Input:}}
\algrenewcommand{\algorithmicensure}{\textbf{Output:}}
\algnewcommand\And{\textbf{and} }

\begin{document}

\begin{figure}
\begin{algorithmic}
\If{$x> y$ \And  $ x<z$}
\State{some code here}
\EndIf
\end{algorithmic}
\end{figure}
\end{document}

Thanks: @Werner

And what is the difference? Did you see the second par of the question? – percusse Mar 23 '15 at 19:25
Sorry I was confused with other algorithms package. – JJoao Mar 23 '15 at 19:35
Note the use here should be \And{}, or define it to include a trailing space: \algnewcommand\And{\textbf{and} }. – Werner Mar 23 '15 at 19:37
@Werner, Thank you! (sorry I was editing and I just saw your suggestion). I don't know: perhaps your solution is better... – JJoao Mar 23 '15 at 19:40

@JJoao: You would most likely not use \And unless you have two operands (one on either side), so it seems logical to define \And to always include a space. xspace is a viable option, noting of course that there might be some drawbacks of using xspace. – Werner Mar 23 '15 at 19:44
For algorithmic and could I use: $ $ \mathrm{and} $ $? – alper Jan 04 '22 at 18:12
\algnewcommand\And2{\textbf{and}}, since \And is defined previously and requires $ $. – remo Aug 15 '23 at 09:47

I suggest use the answer by Werner if you use the algorithmic package. Link: Using the "algorithm" package - can't use \OR?

\documentclass{article}

\usepackage{algpseudocode}

\algnewcommand{\algorithmicand}{\textbf{ and }}
\algnewcommand{\algorithmicor}{\textbf{ or }}
\algnewcommand{\OR}{\algorithmicor}
\algnewcommand{\AND}{\algorithmicand}
\algnewcommand{\var}{\texttt}

\begin{document}

\begin{algorithmic}
  \Procedure{proc}{$v$}
    \State $\var{v.bool} \gets \var{v.bool} \OR \var{c.bool}$;
  \EndProcedure
\end{algorithmic}

\end{document}
