The init_shell() function detects the operating system with the platform module and returns an object that’s an abstraction around the system-specific shell. The code hasn’t implemented the behavior on macOS,
<function strong.<locals>.wrapper at 0x000000000129A268> <function weak_great at 0x000000000129A2F0> When you used the decorator, you took your function, created a new function that wrapped code around your old function and returned that new, anonymous, function. (当你用装饰器时,实际上就是用...

我们以 UE 官方的PythonScriptPlugin中的代码为例, 如果直接依赖 Python C API, 你实现出来的代码可能是如下这样的: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // NOTE: _T = typing.TypeVar('_T') and Any/Type/Union/Mapping/Optional are defines by the Python typing module.staticPyMethodDef...
When you use a Python decorator, you wrap a function with another function, which takes the original function as an argument and returns its modified version. This technique provides a simple way to implement higher-order functions in Python, enhancing code reusability and readability.By the end ...

The function looks up x in the surrounding context, rather than using the value of x at the time the function is created. So all of the functions use the latest value assigned to the variable for computation. We can see that it's using the x from the surrounding context (i.e. not ...
Added type parameter to attrs.field() function for use with attrs.make_class(). Please note that type checkers ignore type metadata passed into make_class(), but it can be useful if you're wrapping attrs. #1107 It is now possible for attrs.evolve() (and attr.evolve()) to change fiel...
