内置模块是编译进 Python 解释器(executable)的 C 模块,随时可以调用。通过 sys.builtin_module_names 可以查看具体内容: $ python -q >>> import sys >>> sys.builtin_module_names ('_abc', '_ast', '_codecs', '_collections', '_functools', '_imp', '_io', '_locale', '_operator', '_...
2) 编译器(compilers):编译源码(source code)为目标代码(object code)(或可执行代码(executable))。 Python程序可由编译器执行,有两种方式:交互模式(interactive mode)和脚本模式(script mode)。 1) 交互模式:当输入1 + 1后,编译器会直接给出结果2。 2) 脚本模式:代码可以文档形式保存,Python脚本文件以.py结尾。
Avoid running the nuitka binary, doing python -m nuitka will make a 100% sure you are using what you think you are. Using the wrong Python will make it give you SyntaxError for good code or ImportError for installed modules. That is happening, when you run Nuitka with Python2 on Python3...

Activating a virtual environment modifies the PATH and shell variables to point to the specific isolated Python set-up you created. PATH is an environmental variable in Linux and other Unix-like operating systems that tells the shell which directories to search for executable files (i.e., ready...
