❤️ 2.python画动态爱心表白
一行代码画心
import time
words = input(‘请输出想要表达的文字:’)
#例子：words = “Dear lili, Happy Valentine’s Day! Lyon Will Always Love You Till The End! ♥ Forever! ♥”
for item in words.split():
#要想实现打印出字符间的空格效果，此处添加：item = item+’ ’
letterlist = []#letterlist是所有打印字符的总list，里面包含y条子列表list_X
for y in range(12, -12, -1):
list_X = []#list_X是X轴上的打印字符列表，里面装着一个String类的letters
letters = ‘’#letters即为list_X内的字符串，实际是本行要打印的所有字符
for x in range(-30, 30):#是乘法，**是幂次方
expression = ((x0.05)**2+(y0.1)**2-1)**3-(x0.05)*2(y*0.1)**3
if expression <= 0:
letters += item[(x-y) % len(item)]
else:
letters += ’ ’
list_X.append(letters)
letterlist += list_X
print(’\n’.join(letterlist))
time.sleep(1.5);
❤️ 3.3D玫瑰花效果
javascript+HTML5的canvas实现情人节3D玫瑰花效果代码,
使用了html5的canvas技术,可呈现出带有3D效果的玫瑰花渐显效果,非常逼真自然
