Message80704
Although it is possible to specify a default value for an append action,
either directly or through the set_default() function, it is not handled
correctly when this default is overruled by the user. Take for example
the following code:
import optparse
parser = optparse.OptionParser()
parser.add_option("-o", "--option", action = "append")
parser.set_defaults(option = ["a"])
options, args = parser.parse_args()
print options
When this is called without arguments the following is printed:
{'option': ['a']} # as expected
But when it is called with for example with -ob the following is
printed:
{'option': ['a', 'b']} # expected {'option': ['b']}
So the default option is also appended, even if the option is explicitly defined by the user. |
