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
