Maybe this will help. In your case,<\/p>\n

def action(file1, file2, behavior=defaultBehavior):\n    return behave(file1, file2)\n<\/code><\/pre>\n
is okay. But of course, if an argument is passed into the “behave” parameter, you should take care of it in your function. For instance, if you called<\/p>\n
action(\"somefile\", \"anotherfile\", customBehavior)\n<\/code><\/pre>\n
then you’ll want something like the following to deal with it:<\/p>\n
def action(file1, file2, behavior=defaultBehavior):\n\n    if behave != defaultBehavior: # this means that behavior was set to something\n        behave(file1, file2, behavior)\n    else: # in this case, behave == defaultBehavior\n        behave(file1, file2)\n<\/code><\/pre>\n
Something similar can be constructed for behave()<\/code>.<\/p>\n<\/p><\/div>\n
