主要通过SICP的内容改写而来。基于newton method求解平方根。代码如下:
#!/usr/bin/python def sqrt_iter(guess,x): if(good_enough(guess, x)): print guess else: sqrt_iter(improve(guess, x),x) def improve(guess, x): return average(guess, x/guess) def average(x,y): return (x+y)/2 def good_enough(guess,x): if(abs(guess * guess -x) < 0.0001): return True else: return False def sqrt_oliver(x): sqrt_iter(1.0,x) sqrt_oliver(5)
希望本文所述对大家的Python程序设计有所帮助。
