介紹

? python中 getopt 模塊，該模塊是專門用來處理命令行參數(shù)的，例如下面這個命令就傳入了 -s, -d , -m 參數(shù)：

python channel_builder.py -s /Users/graypn/ -d /Users/graypn/Documents -m 7

參數(shù)也分長格式和短格式

• 短格式：-s
• 長格式：--source

使用

1. 首先要導入包:

   import sys
   import getopt
   

2. 下面是一段標準模板代碼：

   srcDir = None
   dstDir = None
   platform = "Phone"
   majorVersion = None
   subVersion = None
   channels = None
   try:    
     opts, args = getopt.getopt(sys.argv[1:], "hs:d:m:v:p:c:",                            
   ["help", "src=", "dst=", "major=", "version=", "platform=", "channels="])
   except getopt.GetoptError:    
     showUsage()
   for op, value in opts:    
     if op in ("-h", "--help"):       
        showUsage()    
     elif op in ("-s", "--src"):        
       srcDir = value    
     elif op in ("-d", "--dst"):       
       dstDir = value    
     elif op in ("-m", "--major"):        
       majorVersion = value    
     elif op in ("-v", "--version"):        
       subVersion = value    
     elif op in ("-p", "--platform"):        
       platform = value    
     elif op in ("-c", "--channels"):        
       channels = value
   if srcDir is None or dstDir is None or majorVersion is None or subVersion is None or channels is None:    
       showUsage()
   

   這個 opts 是一個字典類型，getopt.getopt() 函數(shù)第一個傳入?yún)?，第二個傳段參數(shù)名，第三個是長參數(shù)名，上面基本上是固定的格式，所以用到的時候直接復制就好。
