生成200个10位的随机数（生成优惠券）：
__author__ = ‘friday‘
import random
def creat_num(num,long):
str = ‘[email protected]#$%^&*_+‘
b = []
for i in range(num):
a = ‘‘
for j in range(long):
a += random.choice(str)
b.append(a)
for i in range(len(b)):
print(b[i])
if __name__ == ‘__main__‘:
creat_num(200,10)
判断有多少个英文单词：
import re
from collections import Counter
def word_count(txt):
word_pattern = r‘[a-zA-Z-]+‘
words = re.findall(word_pattern, txt)
return Counter(words).items()
if __name__ == ‘__main__‘:
txt = open(‘D:\\f.txt‘, ‘r‘).read().lower()
print word_count(txt)
为头像加数字:
__author__ = ‘Kxrr‘
from PIL import Image,ImageDraw,ImageFont
import random
msgNum = str(random.randint(1,99))
# Read image
im = Image.open(‘D:\\1.jpg‘)
w,h = im.size
wDraw = 0.8 * w
hDraw = 0.08 * w
# Draw image
font = ImageFont.truetype(‘D:\\1.ttc‘, 30) # use absolute font path to fix ‘IOError: cannot open resource‘
draw = ImageDraw.Draw(im)
draw.text((wDraw,hDraw), msgNum, font=font, fill=(255,33,33))
# Save image
im.save(‘D:\\kxrr_msg.png‘, ‘png‘)
有个目录，里面是你自己写过的程序，统计一下你写过多少行代码。包括空行和注释，但是要分别列出来。
import os
import re
def find_path(path):
c = 0
for i in os.listdir(path):
py=os.path.join(path,i)
a=open(py)
commentline = 0
blankline = 0
lines = len(a.readlines())
print "There are %d lines in %s" % (lines, py)
for ii in a.readlines():
pattern = re.compile(r‘(\s*)#‘)
pattern1 = re.compile(r‘(\s*)$‘)
if pattern.match(ii):
commentline += 1
if pattern1.match(ii):
blankline += 1
print "blankline is:",blankline,"commentline is:",commentline
find_path(‘d://1‘)
