cool advanced python scripts code example

Example 1: best python programs

def f(x, y):
    return np.sin(np.sqrt(x ** 2 + y ** 2))
 
x = np.linspace(-6, 6, 30)
y = np.linspace(-6, 6, 30)
 
X, Y = np.meshgrid(x, y)
Z = f(X, Y)fig = plt.figure()
ax = plt.axes(projection='3d')
ax.contour3D(X, Y, Z, 50, cmap='binary')
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z');

Example 2: best python programs

theta = 2 * np.pi * np.random.random(1000)
r = 6 * np.random.random(1000)
x = np.ravel(r * np.sin(theta))
y = np.ravel(r * np.cos(theta))
z = f(x, y)
ax = plt.axes(projection=’3d’)
ax.plot_trisurf(x, y, z,cmap=’viridis’, edgecolor=’none’);
