Python gzip库函数使用方法及实例

<pre name="code" class="python">解压gzip文件示例:import gzipf = gzip.open('file.txt.gz', 'rb')file_content = f.read()f.close()创建gzip文件:import gzipcontent = "Lots of content here"f = gzip.open('file.txt.gz', 'wb')f.write(content)f.close()gzip压缩现有文件: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()

实例：

从/opt/mat/*.gz文件中读取每一行，找到包含'GET~#~ ~#~'或者'POST~#~ ~#~'的输出该行
