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)]))
拆解一下，能看明白点。
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 爱 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)
