You may still use a parser on an unsupported platform - for example, you may want to parse a file with linux lsof output on a macOS or Windows laptop. In that case you can suppress the warning message with the -q cli option or the quiet=True function parameter in parse():macOS:...

By the end of this tutorial, you’ll understand that:pip stands for “pip installs packages”, indicating its primary function. pip manages Python packages that aren’t part of the standard library. You should use pip whenever you need external Python packages for your projects. You can ...

Namespace(accumulate=<built-infunction sum>, integers=[7, -1,42]) 在脚本中,parse_args()通常没有参数,ArgumentParser将自动确定sys.argv中的命令行参数。 parse_args()方法的返回值为namespace,可以用vars()内建函数化为字典 >>> args = parser.parse_args(['--sum','7','-1','42'])>>>args...

在Directory或Script中,CMake代码可以使用include()命令来加载.cmake。cmake内置了许多模块用来帮助我们构建工程,前边文章中提到的CheckFunctionExists。也可以提供自己的模块,并在CMAKE_MODULE_PATH变量中指定它们的位置。 (1)cmake基本编写格式: 举例: add_executable(hello world.c foo.c) #这是一个注释 ...
