python 编程画爱心代码实现如下：

    import time
    words = input('Please input the words you want to say!:')
    # 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(-40, 40):  # *是乘法，**是幂次方
                expression = ((x*0.04)**2+(y*0.1)**2-1)**3-(x*0.04)**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)

执行打印爱心结果如下所示：
