# 日志 # 日志(Logging) 日志是装饰器运用的另一个亮点。这是个例子： ~~~ from functools import wraps def logit(func): @wraps(func) def with_logging(*args, **kwargs): print(func.__name__ + " was called") return func(*args, **kwargs) return with_logging @logit def addition_func(x): """Do some math.""" return x + x result = addition_func(4) # Output: addition_func was called ~~~ 我敢肯定你已经在思考装饰器的一个其他聪明用法了。
