介绍
python中 getopt 模块，该模块是专门用来处理命令行参数的，例如下面这个命令就传入了 -s, -d , -m 参数：
python channel_builder.py -s /Users/graypn/ -d /Users/graypn/Documents -m 7
参数也分长格式和短格式
- 短格式：
-s - 长格式：
--source
使用

首先要导入包:
import sys import getopt -
下面是一段标准模板代码：
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()这个
opts是一个字典类型，getopt.getopt()函数第一个传入参，第二个传段参数名，第三个是长参数名，上面基本上是固定的格式，所以用到的时候直接复制就好。
