兄弟们可以收藏一下哦！情人节可以送出去，肥学找了几朵python写的花给封装好送给大家。不是多炫酷但是有足够的用心哦。别忘了点赞呀我也就不细说了，来吧展示！
源码和详解
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

p = (np.pi / 2) * np.exp(-t / (8 * np.pi))
# 添加边缘扰动
change = np.sin(15*t)/150
# 将t的参数减少，使花瓣的角度变大
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)
