python 之 分割参数getopt

python之分割参数getopt

import sys 
import getopt
  
def usage():  
    print("Usage:%s [-a|-o|-c] [--help|--output] args...." %Dsys.argv[0]);  
  
if "__main__" == __name__:  
    #lsArgs = [""];  
      
    try:  
        opts,args = getopt.getopt(sys.argv[1:], "ao:c", ["help", "output="]);  
      
        print("============ opts ==================");         
        print(opts);  
      
        print("============ args ==================");  
        print(args);  
          
        #check all param  
        for opt,arg in opts:  
            if opt in ("-h", "--help"):  
                usage();  
                sys.exit(1);  
            elif opt in ("-t", "--test"):  
                print("for test option");  
            else:  
                print("%s  ==> %s" %(opt, arg));          
          
    except getopt.GetoptError:  
        print("getopt error!");  
        usage();  
        sys.exit(1);  

运行结果：

$ ./test_getopt.py  -a -oaaa -caa --output=out file1 t file2 -d
============ opts ==================
[('-a', ''), ('-o', 'aaa'), ('-c', ''), ('-a', ''), ('-a', ''), ('--output', 'out')]
============ args ==================
['file1', 't', 'file2', '-d']
-a  ==> 
-o  ==> aaa
-c  ==> 
-a  ==> 
-a  ==> 
--output  ==> out
