When using argparse, is there a way to specify in what order arguments get parsed?
I expect argparse to forward iterate the sequence of arguments that it receives.
I am writing a script whose parameters can be modified in the following order: Defaults -> config file -> command-line switches. However, I want to give the option of specifying a config file using a command line switch as well, so logically, that file should be parsed before any other arguments are applied. However, it seems that parse_args() parses arguments in the order they're given,

config file switch is not given first, the config file will overwrite whatever was in the command-line switches, which should have higher priority.
So just document that a config file has to be given first to work as expected. Order dependence among arguments is common.
