python channel_builder.py -s /Users/graypn/ -d /Users/graypn/Documents -m 7 --out=report/xx.html

參數也分長格式和短格式

短格式：-s

長格式：--source

opts, args = getopt.getopt(sys.argv[1:], "hs:d:m:v:p:c:",

["help", "src=", "dst=", "major=", "version=", "platform=", "channels="])

這個 opts 是一個字典類型，getopt.getopt(x,y,z) x函數第一個傳入參sys.argv[1:]，y第二個傳段short短數名"hs:d:m:v:p:c:"，z第三個是long長參數名["help", "src=", "dst=", "major=", "version=", "platform=", "channels="]

short 用法就是 python test.py -h 111

long用法可以2種 --out=res/tt.html

或者直接 --out res/tt.html

關于第二個參數初學者會很困惑這啥意思:

其實是這樣的單獨一個字母表示該參數不帶值，一個字母加個：比如p:表示該參數后面帶值，"hf:-v"也可以寫成'-h-f:-v',到底什么意思呢：

C:\Users\Administrator\PycharmProjects\checkTest\src>python xx.py -h

this is --help

C:\Users\Administrator\PycharmProjects\checkTest\src>python xx.py -f

Traceback (most recent call last):

File "xx.py", line 22, in

opts, args = getopt.getopt(sys.argv[1:], '-hf:-v', ['help', 'filename=', 'version'])

File "C:\Python37\lib\getopt.py", line 95, in getopt

opts, args = do_shorts(opts, args[0][1:], shortopts, args[1:])

File "C:\Python37\lib\getopt.py", line 199, in do_shorts

opt)

getopt.GetoptError: option -f requires argument

C:\Users\Administrator\PycharmProjects\checkTest\src>python xx.py -h

this is --help

C:\Users\Administrator\PycharmProjects\checkTest\src>python xx.py -f=aaaa.txt

[*] Filename is =aaaa.txt

意思就是你短參數不需要給我指定值，給我我也沒發接受處理比如1000短參數給的值1000也沒用，長參數是你必須給我值我才可以進行傳參
