WebOct 20, 2024 · Python Yield It is generally used to convert a regular Python function into a generator. A generator is a special function in Python that returns a generator object to the caller. Since it stores the local variable states, hence overhead of memory allocation is controlled. Example: def printresult (String) : for i in String: if i == "e": yield i WebApr 11, 2024 · def fibonacci_recursive ( n, memo=dict() ): if n in memo.keys (): return memo [n] elif n <= 1: return n else: result = fibonacci_recursive (n- 1) + fibonacci_recursive (n- 2) memo [n] = result return result #非递归实现斐波那契数列,使用 yield 的生成器实现 def fibonacci_non_recursive (): a, b = 0, 1 while True: yield a a, b = b, a + b #测试函数运行时间
