解压缩文件

Question

我想解压缩* .sec.gz这是一个zip文件的文件。但我事先得到BADFILE .....有人能指导来解决这个.....文件存在的文件夹中类型的* .SEC ........感谢

import zipfile 
def unzip(path): 
    zfile = zipfile.ZipFile(path) 
    for name in zfile.namelist(): 
     (dirname, filename) = os.path.split(name) 
     if filename == '': 
      # directory 
      if not os.path.exists(dirname): 
       os.mkdir(dirname) 
     else: 
      # file 
      fd = open(name, 'w') 
      fd.write(zfile.read(name)) 
      fd.close() 
    zfile.close() 

k=unzip('C://test//08October2014//DATA_INTV_NEW//Oct0814//1.sec.gz') 

输出：

BadZipfile        Traceback (most recent call last) 
<ipython-input-7-5134b63e752e> in <module>() 
    27  zfile.close()

BadZipfile: File is not a zip file

错误消息是完全准确的：这不是一个zip文件。这是一个gzip文件，完全不同。你应该使用gzip module。
