Question

有没有办法使该变量返回“未定义”状态？

Answer 1

在函数内部将变量声明为全局变量。

此外，您还没有调用函数

Answer 2

您有一个可以找到min_x和max_x的函数，但尚未调用它。

像这样调整它：

def visualize(c,x,y):
  min_x,max_x = ...
  min_y,max_y = ...
return min_x,max_x,min_y,max_y

min_x,max_x,min_y,max_y = visualize(c,x,y)
x_vals,y_vals = np.meshgrid(np.arange(min_x,max_x, mesh_step_size))

尝试一下！我认为这会帮助您
