为什么在python中不能运行啊

Question

x, n = input().split()
x = float(x)
n = int(n)

xiang = x
sign = 1
x_mici = x
jiechen = 1.0
sin_x = xiang
for i in range(2, n + 1):
sign *= -1
x_mici *= x * x
jiechen *= (2 * i - 1) * (2 * i - 2)
xiang = sign * x_mici / jiechen
sin_x += xiang

print("%.8f" % sin_x)

Answer 1

你需要输入两个变量，中间用空格分开，例如

1 2
