动画代码块投影仪

我正在尝试将代码块替换为动画。但我无法将其放入或verbatim中。\onslide\visible

我尝试使用savebox，问题是第二个代码块排版在第一个代码块下方。我希望代码块显示在相同位置。

我的代码：

\documentclass{beamer}

\usepackage{fancyvrb}

\begin{document}

\begin{frame}[fragile]{Object}
    \begin{center} 
    \onslide<2>{
\begin{Verbatim}[frame=single, fontsize=\fontsize{7pt}{8pt}\selectfont]
class int(object)
 |  int(x[, base]) -> integer
 |
 |  Convert a string or number to an integer, if possible.  A floating point
 |  argument will be truncated towards zero (this does not include a string
 |  representation of a floating point number!)  When converting a string, use
 |  the optional base.  It is an error to supply a base when converting a
 |  non-string.  If base is zero, the proper base is guessed based on the
 |  string content.  If the argument is outside the integer range a
 |  long object will be returned instead.
    \end{Verbatim}
}
\onslide<3>{
\begin{Verbatim}[frame=single, fontsize=\fontsize{7pt}{8pt}\selectfont]
class int(object)
 |  int(x[, base]) -> integer
 |
    \end{Verbatim}
    }
    \end{center}
\end{frame}

\end{document}

它与 一起起作用，\only<>而不是onslide<>。
