1. ModuleName.__doc__:获取模块的文档 2. dir(ModuleName):获取模块中定义了的名称(属性、方法)的列表 3. help(ModuleName):获取模块的详细帮助手册dir( )函数使用方法其中dir()是很常用的一个内置函数,因为Python内置的函数非常多,程序员不可能全部都记住,所以dir()函数可以帮助我们查看对象内定义的属性...
To fix this warning, stop deriving from std::iterator and start providing publicly accessible typedefs named iterator_category, value_type, difference_type, pointer, and reference. Note that value_type is required to be non-const, even for constant iterators. You can define _SILENCE_CXX17_...
