请问def newton_divided_differences(x, y): n = len(x) F = [[] * n for i in range(n)] for i in range(n): F[i][] = y[i] for j in range(1, n): for i in range(n - j): F[i][j] = (F[i + 1][j - 1] - F[i][j - 1]) / (x[i + j] - x[i]) return F[]报错是什么原因，并给出修改后的代码

抱歉，我可以回答这个问题。根据代码，报错可能是因为F[i][]和F[i 1][j - 1]这两处语法错误。应该将F[i][]改为F[i][]，将F[i 1][j - 1]改为F[i + 1][j - 1]。修改后的代码如下：

def newton_divided_differences(x, y):
n = len(x)
F = [[] * n for i in range(n)]
for i in range(n):
F[i][] = y[i]
for j in range(1, n):
for i in range(n - j):
F[i][j] = (F[i + 1][j - 1] - F[i][j - 1]) / (x[i + j] - x[i])
return F
