兄弟們可以收藏一下哦！情人節(jié)可以送出去，肥學找了幾朵python寫的花給封裝好送給大家。不是多炫酷但是有足夠的用心哦。別忘了點贊呀我也就不細說了，來吧展示！

源碼和詳解

荷花

def lotus():
    fig = plt.figure(figsize=(10,7),facecolor='black',clear=True)
    ax = fig.gca(projection='3d')
    [x, t] = np.meshgrid(np.array(range(25))/24.0, np.arange(0, 575.5, 0.5)/575 * 17 * np.pi-2*np.pi)
    p = (np.pi/2)*np.exp(-t/(8*np.pi))
    u = 1-(1-np.mod(3.6*t, 2*np.pi)/np.pi)**4/2
    y = 2*(x**2-x)**2*np.sin(p)
    r = u*(x*np.sin(p)+y*np.cos(p))
    surf = ax.plot_surface(r*np.cos(t), r*np.sin(t), u*(x*np.cos(p)-y*np.sin(p)), rstride=1, cstride=1, cmap=cm.gist_rainbow_r,
                           linewidth=0, antialiased=True)

玫瑰花

def rose_flower():
    fig = plt.figure(figsize=(10,7),facecolor='black',clear=True)
    ax = fig.gca(projection='3d')
    # 將相位向后移動了6*pi
    [x, t] = np.meshgrid(np.array(range(25)) / 24.0, np.arange(0, 575.5, 0.5) / 575 * 20 * np.pi + 4*np.pi)
    p = (np.pi / 2) * np.exp(-t / (8 * np.pi))
    # 添加邊緣擾動
    change = np.sin(15*t)/150
    # 將t的參數(shù)減少，使花瓣的角度變大
    u = 1 - (1 - np.mod(3.3 * t, 2 * np.pi) / np.pi) ** 4 / 2 + change
    y = 2 * (x ** 2 - x) ** 2 * np.sin(p)
    r = u * (x * np.sin(p) + y * np.cos(p))
    h = u * (x * np.cos(p) - y * np.sin(p))
    c= cm.get_cmap('Reds')
    surf = ax.plot_surface(r * np.cos(t), r * np.sin(t), h, rstride=1, cstride=1,
                           cmap= c, linewidth=0, antialiased=True)
