In this example, we first import theosmodule. We then define a variablefile_paththat holds the name of the file we want to check. We pass this variable to theos.path.exists()function inside anifstatement. If the file exists, it prints ‘The file exists!’, and if it doesn’t, it p...

local scope will change global variable due to same memory used input: importnumpyasnpdeftest(a):a[0]=np.nanm=[1,2,3]test(m)print(m) output: [nan, 2, 3] Note python has this really weird error if you define local variable in a function same name as the global variable, program...
if not os.path.exists(directoryName): os.makedirs(directoryName) 这就完成了我们的downloadProcess功能,同时也完成了我们简单的网络机器人。试一试,把它指向 http://www.irrelevantcheetah.com/browserimages.html ,询问 jpg、pdf 或 txt 文件类型,然后看它创建文件夹和下载文件——所有这些都不需要你的帮助。

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 ...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
Note: When the debugger performs a reload, code that runs on import might be executed again. To avoid this situation, try to only use imports, constants, and definitions in your module, placing all code into functions. Alternatively, you can also useif __name__=="__main__"checks. ...
