问我如何调整这个牛顿-拉斐逊循环，以包括一个范围的值，为我的初步猜测，以便它打印的迭代次数为每个？

#Define Newton-Raphson method as a function using a for loop
def nraphson(fn, dfn, x, tol, maxiter):
    for i in range(maxiter):
        xnew = x - fn(x)/dfn(x)
        if abs(xnew - x) < tol: break
        x = xnew
    return xnew, i

#Define f(x) and f'(x) to be used in Newton-Raphson function
y = lambda x: math.exp(x) - x**2
dy = lambda x: math.exp(x) - 2*x

#Run the Newton-Raphson method with initial x as -1 from estimate
x, n = nraphson(y, dy, -1, 0.0001, 100)
#Printing text allows us to see the value determined for the root
print("the root is %f at %d iterations." % (x,n))
