level of the current interpreter, as given by -O command line options.optimize为1时，优化字节码级别为最高 -1和0：设置pyc优化级别 1和2：设置pyo优化级别 数字越小，优化级别越高 准备源文件a.py和b.py，内容相同，就是一句print("python")代码 编写编译脚本：import py_compile py_compile.compile(fi...
import py_compile py_compile.compile("hello.py") 再在终端中:python hello.pyc 3)在终端中: python -O -m py_compile hello.py python hello.pyo 编译成.pyc和.pyo文件后,执行的速度会更快。所以一般一些重复性并多次调用的代码会被编译成这两种可执行的方式来待调用。 二、变量、运算与表达式 这里没什...
通过compile()函数和dis模块的code_info()函数来检测我们执行的命令的信息。示例: 可以看出,分别赋值a,b得到的value相等,id是不一样的。 把10.0 10.0 10.1分别赋值给a,b,c,可以看出结果中其实只保存了一个10.0,也就是a,b共用了这个数值。也就是说,当命令行执行时,是以single的模式来compile代码(https://doc...

Python does not check the cache in two circumstances. First, it always recompiles and does not store the result for the module that’s loaded directly from the command line. Second, it does not check the cache if there is no source module. To support a non-source (compiled only) distri...
