Hello all:
I am using getopt package in Python and found a problem that I can not
figure out an easy to do .
// Correct input
D:\>python AddArrowOnImage.py --imageDir=c:/
// Incorrect input
D:\>python AddArrowOnImage.py --imageDi
Traceback (most recent call last):
File "AddArrowOnImage.py", line 113, in ?
File "AddArrowOnImage.py", line 88, in main
File "getopt.pyc", line 89, in getopt
File "getopt.pyc", line 157, in do_longs
getopt.GetoptError: option --imageDir requires argument
Is there any method in getopt or Python that I could easily check the
validity of each
command line input parameter?
Thank you
-Daniel
FYI: My code that deals with getopt is as follows:
o, a = getopt.getopt(sys.argv[1:], 'h', ['imageDir='])
opts = {}
for k,v in o:
if k in ['--imageDir'] and len(v) == 0:
usage(); sys.exit("Insufficient input parameters!")
opts[k] = v
if opts.has_key('-h'):
usage(); sys.exit(0)
if not len(opts['--imageDir']):
usage(); sys.exit("Insufficient input parameters!")
