7.cipin词频统计
做一个词频统计程序,该程序具有以下功能
基本要求:
(1)可导入任意英文文本文件
(2)统计该英文文件中单词数和各单词出现的频率(次数),并能将单词按字典顺序输出。
(3)将单词及频率写入文件。
提高要求:
完成基本要求的基础上,实现下述功能:
1.实现GUI界面。
2.将单词及频率写入数据库。
实现思路:
定义一个单词容器类wordcol,有两个属性,第一个属性为单词本身,第二属性就是出现次数。用一个map来统计,map的key为单词本身,value为wordcol对象。先将一篇文章清洗干净,过滤掉所有的标点符合等,这个用正则表达式即可。然后将大写的字母小写,因为大写和小写不形象单词本身的出现次数,再将单词按照空格分割,分割后得到一个数组就是所有的单词,但是可能包含空格。所以在统计的时候加以判断。
经典分拣思路:
遍历这一堆单词数组,每次取出一个单词,用map的get方法获得value值。如果value为空,则说明,这个单词还没有被统计过,则创建一个新的wordcol,次数为1,然后加入到map中。如果不为空则将获得到的value即wordcol对象中的次数属性加一。加了一个单词首字母排序的功能,即将key进行一个排序,然后按照排序后的key输出,或者直接用treemap。
import re
file = open('flag.txt')
line = file.readlines()
file.seek(0,0)
file.close()
result = {}
for i in range(97,123):
count = 0
for j in line:
find_line = re.findall(chr(i),j)
count += len(find_line)
result[chr(i)] = count
res = sorted(result.items(),key=lambda item:item[1],reverse=True)
num = 1
for x in res:
print('频数第{0}: '.format(num),x)
num += 1
8.LSB按行读取rgb转换0和1
from PIL import Image
im=Image.open('gray.png')
width=im.size[0]
height=im.size[1]
fh=open('1.txt','w')
for h in range(height):
for w in range(width):
color=im.getpixel((w,h))
# print color
colorsum=color[0]+color[1]+color[2]
if(colorsum == 0):
fh.write('1')
else:
fh.write('0')
fh.close()
9.根据RGB数值自动因式分解画图
from PIL import Image
def Crack(n):#yinshufenjie
flag = []
for each in range(2,int(n **0.5)+1):
if(n % each == 0):
print(each,int(n/each))
flag += [(each,int(n/each))]
if len(flag) == 1:return flag[0]
else:
choice = input("Which group to select(0-%s):"%(len(flag)-1))
return flag[int(choice)]
def Paint(X,Y,listrgb):#Draw according to string list
pic = Image.new("RGB",(X, Y))
i=0
for x in range (0,X):
for y in range (0,Y):
temp = listrgb[i].split(',')
pic.putpixel([x,y],(int(temp[0]),int(temp[1]),int(temp[2])))
i = i+1
pic.show()
pic.save(r"/root/flag%s.png"%(X))
listrgb = open(r"/root/1.txt").readlines()
X,Y = Crack(len(listrgb))
Paint(X,Y,listrgb)
Paint(Y,X,listrgb)
10.批量提取文件名
@echo off
for /f "delims=" %%a in ('dir /b/a-d/oN *.*') do echo %%a >>1.txt
11.还原图片
from PIL import Image
x = 320
y = 245
im = Image.new('RGB', (x, y))
with open('hint.txt') as f:
for i in range(x):
for j in range(y):
line = f.readline().replace('\n','')
s = line.split(',')
im.putpixel((i, j), (int(s[0]), int(s[1]), int(s[2])))
im.save('d.png')
