python正則表達式进行日志分析
日志分析时,如果给定的字符串:
char str = “10.10.1.1 [2015/04/22 +0800] /ab/cd/?test0=123&test2=234 xxxx”; 要从中获取2015/04/22、/ab/cd/和234等值。
str = “10.10.1.1 [2015/04/22 +0800] /ab/cd/?test0=123&test2=234 xxxx”
print(re.findall(“d{4}/d{2}/d{2}|/w{2}/w{2}|(?<=test2=)d+”, str))
用urllib2、re、os 模块下载文件的脚本
!/usr/bin/env pythonimporturllib2
importre
importos
URL=’http://image.baidu.com/channel/wallpaper’
read=urllib2.urlopen(URL).read()
pat =re.compile(r’src=’#’” //.+?.js”>’)
urls=re.findall(pat,read)
fori inurls:
url=i.replace(‘src=’#’” /code>,”).replace(‘”>’,”)
try:
iread=urllib2.urlopen(url).read()
name=os.path.basename(url)
with open(name,’wb’) as jsname:
jsname.write(iread)
except:
printurl,”url error”
将全部文档中不同问题分别汇总到同一个文件里
def shift(): ''' 筛选全部人不同问题的答案到相应的文件里 :return: ''' INPUT_DIR = r'C:UserspiDesktop xts' ANSWER_DIR = r'C:UserspiDesktopanswers' if not path.exists(ANSWER_DIR): makedirs(ANSWER_DIR) questions = ['在计科四班度过大学四年是一种如何的体验', '对班上的哪位同学第一印象最深刻,简述原因', '简述让你印象深刻的班上某位同学的一件小事', '想对你的室友说什么', '大学你最遗憾的事', '最难忘或最感动或最想珍惜的一件事或人', '立即要毕业了,此刻的你内心是一种如何的体验', '想对你暗恋or前女友or现任恋人说什么', '(写完后记得将文档重命名加上你的姓名)'] answer_filenames = [str(i) + '.txt' for i in range(len(questions) - 1)] for doc_name in listdir(INPUT_DIR): print(doc_name) doc_full_name = path.join(INPUT_DIR, doc_name) # print(doc_full_name) open(doc_full_name) with open(doc_full_name) as doc_file: # file_str = ''.join(doc_file.read().split(' ')) file_str = doc_file.read() # print(file_str) for cur_question, post_question, answer_filename in zip(questions, questions[1:], answer_filenames): patten = cur_question 相关阅读:
