Options and arguments (and corresponding environment variables): -c cmd : program passed in as string (terminates option list) -d : debug output from parser (also PYTHONDEBUG=x) -E : ignore environment variables (such as PYTHONPATH) -h : print this help message and exit [ etc. ] ...
ENVIRONMENT VARIABLES PYTHONHOME Change the location of the standard Python libraries. By default, the libraries are searched in ${prefix}/lib/python<version> and ${exec_prefix}/lib/python<version>, where ${prefix} and ${exec_prefix} are installation-dependent directories, both defaulting to /...
Add Python to environment variables：将Python解释器程序添加到环境变量。Precompile standard library：预先编译标准库，可以加快Python程序的运行速度。Download debugging symbols：下载调试符号。开发者可用。一般情况下可执行文件为了节省空间，不会记录源代码中的变量名，调试符号用来记录源代码中的变量名的，一般是调试...

Step 5 — Creating a Virtual Environment Now that we have Xcode, Homebrew, and Python installed, we can go on to create our programming environment. Virtual environments enable you to have an isolated space on your computer for Python projects, ensuring that each of your projects can have its...
-d : debug output from parser (also PYTHONDEBUG=x) -E : ignore environment variables (such as PYTHONPATH) -h : print this help message and exit [ etc. ] 我们在使用脚本形式执行 Python 时,可以接收命令行输入的参数,具体使用可以参照Python 3 命令行参数。
