Arguably, this is the worst way to handle this. The defaults can no longer be rendered by --help and their values are moved somewhere completely apart from where they should be.

If we're going to move default values elsewhere, we should use argparse.SUPPRESS to more clearly signal that the option was not provided on the CLI altogether. That's the clearest and best way to accomplish what you want, even if it still hides and makes it impossible to introspect the defaults

@sigmavirus24 thanks for the information about argparse.SUPPRESS I never used it.
I just update the PR with that information.

@ericwb @sigmavirus24 All changes done.
Thanks for your feedback.

So rather than relying on argparse.SUPPRESS to tell us whether something was specified, you're still setting it to something before using it which seems to completely defeat the purpose. That doesn't make a whole lot of sense to me

@sigmavirus24 i don't know any other way to detect if the user have enter the value via cli or not, if default value is set there is no any elegant way to know if there come from the sys.argvs or is the default value.
Or we set None as default or argparse.SUPPRESS in both ways we need set the default value when the ini file was processed, in other case the ini values will be discarded.

Please let me know how could i do for solve this issue? i'll happy to do it as you prefer
