#getopt

import getopt

import sys

try:    opts, args = getopt.getopt(sys.argv[1:], "ho:", ["help", "output="]) except getopt.GetoptError:    # print help information and exit

try:    opts, args = getopt.getopt(sys.argv[1:], " 短格式 ", [ 長格式 ])

上面的例子。

短格式： -h  / -o 後有一個參數 

長格式：--help / --output= 後有一個參數

如果輸入的令命列為 xxx.py -h -o file --help --output=out file1 file2

sys.arg[0] = “xxx.py” 

opts = [('-h', ''), ('-o', 'file'), ('--help', ''), ('--output', 'out')]
