本文实例讲述了python获取Linux下文件版本信息、公司名和产品名的方法,分享给大家供大家参考。具体如下:

区别于前文所述。本例是在linux下得到文件版本信息,主要是通过pefile模块解析文件 中的字符串得到的。代码如下:

  def _get_company_and_product(self, file_path): 
    """ 
    Read all properties of the given file return them as a dictionary. 
    @return: a tumple, (company, product) 
    """ 
    mype = pefile.PE(file_path) 
    companyName = "" 
    productName = "" 
      
    if hasattr(mype, 'VS_VERSIONINFO'): 
      if hasattr(mype, 'FileInfo'): 
        for entry in mype.FileInfo: 
          if hasattr(entry, 'StringTable'): 
            for st in entry.StringTable: 
              for k, v in st.entries.items(): 
                if k == u"CompanyName": 
                  companyName = v 
                elif k == u"ProductName": 
                  productName = v 
    if not companyName: 
      companyName = None 
    if not productName: 
      productName = None 
    return (companyName, productName) 

Copy after login

这里我们只要了公司名称信息和产品名称信息。至于版本号之类的信息也是在字符串资源中。

希望本文所述对大家的Python程序设计有所帮助。
