Recursion in Python: An Introduction – Real Python

Webb0. All solutions to the recurrence relation a n + 1 = s a n + t with s ≠ 1 have the form: a n = c 1 s n + c 2, where c 1 and c 2 are specific constants. In the problem s = 1 / 2. Therefore, a n = c 1 ( 1 / 2) n + c 2. Taking into account a 0 = 4 and a 1 = 3, one can obtain c 1 = 2 = c 2. Hence, a n = 2 1 − n + 2. Webb递归（英語： Recursion ），又译为递回，在数学与计算机科学中，是指在函数的定义中使用函数自身的方法。递归一词还较常用于描述以自相似方法重复事物的过程。例如，当两面镜子相互之间近似平行时，镜中嵌套的图像是以无限递归的形式出现的。也可以理解为自我复制的过程。目录 1 语言例子 2 正式定义 3 數學之應用 3.1 實例：自然數 3.2 … mcadams theory of generativityWebbThe limit on the number of levels of recursion that will be used in evaluating an expression is given by the value of $RecursionLimit.
