auk's interface consists almost entirely of a single function -compile_predicate, which accepts an s-expression and compiles it into Python's function or lambda. Its signature is as follows: defcompile_predicate(sexp:List,funcname:str=None,force_func:bool=False,force_lambda:bool=False)->Union...

python条件变量`wait_for`predicate未立即返回 Python条件变量是多线程编程中的一种同步机制,用于控制线程的执行顺序和共享资源的访问。条件变量通常与锁对象一起使用,以实现线程之间的协调和通信。 在Python中,条件变量的wait_for方法用于等待某个条件的发生。它接受一个谓词函数作为参数,该函数用于判断条件是否满足。

Predicative dispatch decorator for Python, based on the idea fromFunctional Programming in Python. The module is providing means to specify conditions with a lambda function that determines which function is called. The number of arguments in the condition function in the@predicatedecorator must be eq...
