可以使用:

vlines(x, ymin, ymax)

hlines(y, xmin, xmax)

import matplotlib.pyplot as pltimport numpy as npdef Laplacian_Prior(x, u, b):        return 1.0/(2*b)*np.exp(-abs(x - u)/b)if __name__ == "__main__":        x = np.arange(-10, 10, 0.01)    y_1 = Laplacian_Prior(x, 0, 1)    y_2 = Laplacian_Prior(x, 0, 2)    y_3 = Laplacian_Prior(x, 0, 4)    y_4 = Laplacian_Prior(x, -5, 4)    plt.plot(x, y_1, "r-")    plt.plot(x, y_2, "k-")    plt.plot(x, y_3, "b-")    plt.plot(x, y_4, "g-")    plt.vlines(0, 0, 0.5, colors = "c", linestyles = "dashed")
