3.关于pyc和egg文件

pyc文件：

pyc文件，是python编译后的字节码（bytecode）文件。只要运行了py文件，python编译器就会自动生成一个对应的pyc字节码文件。这个pyc字节码文件，经过python解释器，会生成机器码运行（这也是为什么pyc文件可以跨平台部署，类似于java的跨平台，java中JVM运行的字节码文件）。下次调用直接调用pyc，而不调用py文件。直到你这个py文件有改变。python解释器会检查pyc文件中的生成时间，对比py文件的修改时间，如果py更新，那么就生成新的pyc。

A program doesn't run any faster when it is read from a ‘.pyc’ or ‘.pyo’ file than when it is read from a ‘.py’ file; the only thing that's faster about ‘.pyc’ or ‘.pyo’files is the speed with which they are loaded.

When a script is run by giving its name on the command line, the bytecode for the script is never written to a ‘.pyc’ or ‘.pyo’ file. Thus, the startup time of a script may be reduced by moving most of its code to a module and having a small bootstrap script that imports that module. It is also possible to name a ‘.pyc’ or ‘.pyo’file directly on the command line. 在import 别的 py 文件时，那个 py 文件会被存一份 pyc加速下次装载。而主文件因为只需要装载一次就没有存 pyc
egg文件：
    根据上面的install提示信息，egg文件应该类似于一个包文件，含有所有的pyc文件和信息文件。
