介绍性能分析器
<p style="margin:10px auto; padding-top:0px; padding-bottom:0px; color:rgb(68,sans-serif; font-size:12px; line-height:1.5!important">
profiler是一个程序，用来描述运行时的程序性能，并且从不同方面提供统计数据加以表述。Python中含有3个模块提供这样的功能，分别是cProfile,profile和pstats。这些分析器提供的是对Python程序的确定性分析。同时也提供一系列的报表生成工具，允许用户快速地检查分析结果。

Python标准库提供了3个不同的性能分析器：

<ol style="margin:0px; padding:0px 0px 0px 40px; color:rgb(68,sans-serif; font-size:12px">
<li style="margin:0px 0px 1em; padding:0px; list-style:decimal">cProfile，推荐给大部分的用户，是C的一个扩展应用，因为其合理的运行开销，所以适合分析运行时间较长的。是基于lsprof。
