不知道怎么向女神表白？Python三大神技分分钟带你成功逆袭！

一行python的表白

首先祭出绝招，用1行python表白：

print('
'.join([''.join([('i love u'[(x-y) % 8] 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)]))

效果如下：

ui love love ui l
ove ui love ui lo ui love ui love u
love ui love ui love ui love ui love ui l
love ui love ui love ui love ui love ui lov
love ui love ui love ui love ui love ui love
ove ui love ui love ui love ui love ui love u
ve ui love ui love ui love ui love ui love ui
e ui love ui love ui love ui love ui love ui
ui love ui love ui love ui love ui love ui l
ui love ui love ui love ui love ui love ui lo
love ui love ui love ui love ui love ui lo
ove ui love ui love ui love ui love ui lo
ve ui love ui love ui love ui love ui lov
ui love ui love ui love ui love ui lo
love ui love ui love ui love ui lo
ove ui love ui love ui love ui lo
ui love ui love ui love ui l
love ui love ui love ui
ve ui love ui love ui
i love ui love
ve ui lov
i l
l

原理大概是：

words, line = "i love u", []
for y in range(15, -15, -1):
line_c = []
letters = ''
for x in range(-30, 30):
expression = ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3
if expression <= 0:
letters += words[(x-y) % len(words)]
else:
letters += ' '
line_c.append(letters)
line += line_c
print('
'.join(line))

进一步可以制作成动画：

def heart_text_animation(words="i love u"):
import time
for c in words.split():
line = []
for y in range(15, -15, -1):
line_c = []
letters = ''
for x in range(-30, 30):
expression = ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3
if expression <= 0:
letters += c[(x-y) % len(c)]
else:
letters += ' '
line_c.append(letters)
line += line_c
print('
'.join(line))
time.sleep(1)

照片墙

依赖： pip install image clize

使用： python picture_wall.py --help

usage: picture_wall.py [options] [text...]
生成照片墙
arguments:
text... text of picture wall, if not defined this will generage a rectangle picture wall
options:
-s, --font-size=int font size of a clear value (default: 20)
-e, --edge-len=int sub picture's egde length (default: 50)
-w, --wall-width=int picture number of rectangle width (default: 20)
-l, --wall-length=int picture number of rectangle length (default: 10)
-d, --pic-dir=str picture's path (default: ./img)
-o, --out-dir=str output dir (default: ./out/)
-p, --font-path=str font path (default: ./demo.ttf)
-m, --method=str decrator method, now accept 'alpha', 'size' (default: alpha)
other actions:
-h, --help show the help

for example:

./picture_wall.py i love u -s 30 -e 10

./picture_wall.py 我爱你 -s 30 -e 10

如果指定为相册文件夹的话，将得到如下效果（文件夹下图片太多而且太大的话会比较慢）：

也可以选择尺寸的方式调整子图，例如: python picture_wall.py 1314 -m size

todo

子照片的处理方式有待提升，目前采用的只是根据字体像素透明度控制透明度，还可以抽象出来让用户选择控制方式～比如：
根据字体像素透明度控制子图形状
根据字体像素透明度控制子图颜色亮度
或者直接采用圆形裁剪子图

爱心情书

依赖： pip install jieba numpy pandas matplotlib wordcloud scipy wordcloud

使用： python heart_cloud_word.py --help

usage: ./heart_cloud_word.py [options] [par...]
生成文字云
arguments:
par...
options:
-t, --text-file=str text file that contain all you word (default: ./data/love_letter.txt)
-s, --stop-file=str the stop word which can't be considered (default: ./data/stopwords.txt)
-c, --color-img=str the color map img (default: ./data/pink.jpg)
-m, --mask-file=str the mask img for the word
-o, --out-file=str output file path which should with sufix of png/jpg... (default: ./out/word_cloud.png)
-p, --font-path=str font path (default: ./demo.ttf)
other actions:
-h, --help show the help

for example:

./heart_cloud_word.py
