一行代码画爱心

print('\n'.join([''.join([('Love'[(x-y)%len('Love')] if ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' ') for x in range(-30,30)]) for y in range(15,-15,-1)]))

拆解

a = [
        ''.join(
            [
                (
                    'Love'[(x-y)%len('Love')]
                    if ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' '
                )
                for x in range(-30,30)
            ]
        )
        for y in range(15,-15,-1)
    ]

print('\n'.join(a))

输出 I ❤ U

空格与星号可以换位置，运行会有不一样的效果。

import time
y = 2.5
while y>=-1.6:
    x = -3.0
    while x<=4.0:
        if (x*x+y*y-1)**3<=3.6*x*x*y*y*y or (x>-2.4 and x<-2.1 and y<1.5 and y>-1) or (((x<2.5 and x>2.2)or(x>3.4 and x<3.7)) and y>-1 and y<1.5) or (y>-1 and y<-0.6 and x<3.7 and x>2.2):
            print('*',end="")
        else:
            print(' ',end="")
        x += 0.1
    print()
    time.sleep(0.25)
    y -= 0.2

填充型

输出五个爱心，分别由Dear I love you forever! 五个单词填充而成。

import time
sentence = "Dear, I love you forever!"
for char in sentence.split():
   allChar = []
   for y in range(12, -12, -1):
       lst = []
       lst_con = ''
       for x in range(-30, 30):
            formula = ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3
            if formula <= 0:
                lst_con += char[(x) % len(char)]
            else:
                lst_con += ' '
       lst.append(lst_con)
       allChar += lst
   print('\n'.join(allChar))
   time.sleep(1)
