「Create an empty file insidemypythonlibthat is called__init__.py. Basically, any folder that has an__init__.pyfile in it, will be included in the library when we build it. Most of the time, you can leave the__init__.pyfiles empty. Upon import, the code within__init__.pygets...

# Filename : helloworld.py print'Hello World' (源文件:code/helloworld.py) 为了运行这个程序,请打开shell(Linux终端或者DOS提示符),然后键入命令python helloworld.py。如果你使用IDLE,请使用菜单Edit->Run Script或者使用键盘快捷方式Ctrl-F5。 输出如下所示。
# As distributed, this file is called Makefile.pre.in; it is processed # into the real Makefile by running the script ./configure, which # replaces things like @spam@ with values appropriate for your system. # This means that if you edit Makefile, your changes get lost the next ...
其中cmake .. 在build里生成Makefile,make应当在有Makefile的目录下,根据Makefile生成可执行文件。 二、编写方法 # 声明要求的cmake最低版本 cmake_minimum_required( VERSION 2.8 ) # 添加c++11标准支持 set( CMAKE_CXX_FLAGS "-std=c++11" )
Common Mistake #10: Misusing the__del__method Let’s say you had this in a file calledmod.py: import fooclassBar(object): ...def__del__(self): foo.cleanup(self.myhandle) And you then tried to do this fromanother_mod.py:
