Python Day 2: Christmas Tree
Last time I went to pick up a real Christmas tree was with Little Charles. It was a really big tree, I have to hold it on the way back.
This year I don’t have a real tree, so I made a Christmas tree with Python.
Code:
import matplotlib as mpl
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
import matplotlib.pyplot as plt
theta = np.linspace(-8 * np.pi, 8 * np.pi, 300)
z = np.linspace(-3, 0, 300)
r = 8
x = r * np.sin(theta)*z
y = r * np.cos(theta)*z
fig = plt.figure() # Create figure
ax = fig.gca(projection=’3d’) # It’s a 3D Xmas tree!
ax.view_init(15, 0) # Set a nice view angle
ax._axis3don = False # Hide the 3d axes
ax.plot(x, y, z,
c=’green’, linewidth=2.5)
# Every Xmas tree needs a star
ax.scatter(0, 0, 0.2,
c=’red’, s=300, marker=’*’)
# Type here your best whishes
ax.set_title(“Merry Christmas !”)
plt.show()
Happy Studying! 🎁
