Examples from the Library Reference: Doc/lib/libgetopt.tex
|
|
|

An example using only Unix style options:
|
|
|
|
|
|
>>> import getopt
|
|
>>> args = '-a -b -cfoo -d bar a1 a2'.split()
|
|
>>> args
|
|
['-a', '-b', '-cfoo', '-d', 'bar', 'a1', 'a2']
|
|
>>> optlist, args = getopt.getopt(args, 'abc:d:')
|
|
>>> optlist
|
|
[('-a', ''), ('-b', ''), ('-c', 'foo'), ('-d', 'bar')]
|
|
>>> args
|
|
['a1', 'a2']
|
|
|
|
Using long option names is equally easy:
|
|
|
|
|
|
>>> s = '--condition=foo --testing --output-file abc.def -x a1 a2'
|
|
>>> args = s.split()
|
|
>>> args
|
|
['--condition=foo', '--testing', '--output-file', 'abc.def', '-x', 'a1', 'a2']
|
|
>>> optlist, args = getopt.getopt(args, 'x', [
|
|
... 'condition=', 'output-file=', 'testing'])
|
|
>>> optlist
|
|
[('--condition', 'foo'), ('--testing', ''), ('--output-file', 'abc.def'), ('-x', '')]
|
|
>>> args
|
|
['a1', 'a2']
