Get Sample Code: Click here to get the sample code you’ll use to learn about complex numbers in Python in this tutorial. If you don’t like calling the complex() factory function, you can create a type alias with a better-suited name or use the literal form of a complex number to ...
使用静态分析(static analysis)技术,在运行时之前对代码进行预处理和优化,例如消除冗余操作、推断类型信息、重排指令顺序等。 改进字节码指令(bytecode instructions)的定义和生成,使其更清晰、更高效、更易于维护和扩展。 改进内存管理(memory management)机制,减少内存分配和垃圾回收的开销,提高内存利用率和缓存友好性。
算法执行所需的时间,有时被称为算法的执行时间或运行时间,可以通过基准分析(benchmark analysis)来测量函数的执行时间,比如之前定义的函数SumOfN。这意味着我们将记录程序计算出结果所需的实际时间,这个实现很简单,在Python中,通过记录相对于系统的开始时间和结束时间来对函数进行基准测试。
