Python gzip庫函數使用方法及執行個體

<pre name="code" class="python">解壓gzip檔案樣本:import gzipf = gzip.open('file.txt.gz', 'rb')file_content = f.read()f.close()建立gzip檔案:import gzipcontent = "Lots of content here"f = gzip.open('file.txt.gz', 'wb')f.write(content)f.close()gzip壓縮現有檔案:import gzipf_in = open('file.txt', 'rb')f_out = gzip.open('file.txt.gz', 'wb')f_out.writelines(f_in)f_out.close()f_in.close()

執行個體：

從/opt/mat/*.gz檔案中讀取每一行，找到包含'GET~#~ ~#~'或者'POST~#~ ~#~'的輸出該行

#!/usr/bin/python#!encoding:utf8import shutilimport osimport sysimport globimport reimport gzip#掃描目錄檔案def parseFile(filename):    #開啟檔案，遍曆其中的每一行遇到有'GET~#~ ~#~'或者'POST~#~ ~#~'的輸出該行    file = gzip.open(filename, 'rb')    #eachline = file.readlines()    for eachline in file:        #str = eachline        #if eachline == "*GET~#~ ~#~*" or eachline == "*POST~#~ ~#~*":        if eachline.find("GET~#~ ~#~") or eachline.find("*POST~#~ ~#~*"):            print(eachline)    file.close()if __name__ == '__main__':    scandir = '/opt/mat/'    fileform = '*.gz'    flist = glob.glob(os.path.join(scandir, fileform))    for item in flist:        print(item)        parseFile(item)
