如何在Python语言中不使用numpy.linspace()创建线性函数

def create_linear_function(start, stop, num_points):
    step = (stop - start) / (num_points - 1)
    x_values = []
    y_values = []
    current_x = start

    for _ in range(num_points):
        x_values.append(current_x)
        y_values.append(current_x)  # 线性函数的斜率为1，截距为0
        current_x += step

    return x_values, y_values

x, y = create_linear_function(0, 10, 5)
print(x)  # 输出：[0, 2.5, 5.0, 7.5, 10.0]
print(y)  # 输出：[0, 2.5, 5.0, 7.5, 10.0]
