My docment class is book. The default setting make \part stay on a single page but with page number. How to remove the page number?

If I want to customize the part? How to do? Is the titlesec package helpful?

Answer 1

Without any package you can do this be redefining the relevant code for the \part command in the preamble of your document.

\documentclass[11pt]{book}
\usepackage[T1]{fontenc}

\makeatletter
\renewcommand\part{%
  \if@openright
    \cleardoublepage
  \else
    \clearpage
  \fi
  \thispagestyle{empty}%   % Original »plain« replaced by »emptyx
  \if@twocolumn
    \onecolumn
    \@tempswatrue
  \else
    \@tempswafalse
  \fi
  \null\vfil
  \secdef\@part\@spart}
\makeatother

\begin{document}
  \part{Foo}
\end{document}

Might also be done by patching the \part command with the »etoolbox« package
