python 执行文件时额外参数获取的实例

def usage():  print(' * usage:')  print(' *  -c [val] : exporter_conf filepath, default importer_conf.')  print(' *  -h : print this.')  print(' *  -z : 不需要确认参数，直接执行')do_not_confirm = Falseconf = ''#c: [c+冒号表示-c 后面有参数，hz表示-h,-z后面没参数,如果此时在-h 100加上参数，那么这个100的值是获取不到的] opts, args = getopt.getopt(sys.argv[1:], 'c:hz') for op, value in opts:  value = value.replace('/'', '').replace('/"', '')  if op == '-c':    conf = value  elif op == '-h':    usage()    sys.exit()  elif op == '-z':    do_not_confirm = True
