#dict()函数后面第一参数是dictionary,其他参数必须是多个展开的确定项如dict(d1,a=3,b=4,c=5),不能是dict,如果传入一个dict可以使用**kwargs传递,如 d3 = dict(d1,**{'a': 3, 'c': 5, 'b': 4}) #*args 和**kwargs a)*args 和**kwargs做实参 传递整体对象匹配函数的多个形参,*args ...

Ideally, all op_kwargs dictionary values should be sent to operators as base64 encoded string and decoded by an operator to avoid templating errors for entries like passwords containing special characters. As a workaround, encoding was done by user and decoded in callable method How to reproduce...
__name__) return func(*args, **kwargs) return out @debug def add(x, y): return x + y Wraps is a helper decorator that copies metadata of function add() to function out(). Without it 'add.__name__' would return 'out'. LRU Cache Decorator that caches function's return values....
Method iter() is required for 'isinstance(<obj>, abc.Iterable)' to return True, however any object with getitem() will work with any code expecting an iterable. MutableSequence, Set, MutableSet, Mapping and MutableMapping ABCs are also extendable. Use '<abc>.__abstractmethods__' to get ...

To fix this, you need to make sure the wrapper function returns the return value of the decorated function. Change your decorators.py file:Python decorators.py def do_twice(func): def wrapper_do_twice(*args, **kwargs): func(*args, **kwargs) return func(*args, **kwargs) return ...
