[Python] How to call a function wrapped inside click from another code

I have a python function which would like to call another function wrapped inside click.

So something like this:

@click.command()
@click.argument('expected', type=click.Path('r'))
@click.argument('observed', type=click.Path('r'))
@click.option('-o1', '--option1', default=None)
@click.option('--option2', type=click.INT, default=0)
main_compare(expected, observed, option1, option2):
......
...


and I am calling it inside another function (in another .py file) like this:

def callingFunction():
main_compare(["expected",input_data_file, "observed", output_file, "--option1", option1, "--option2", option2])



Is this is the right way to call it? I am getting some errors. Can someone confirm the right way to call such a function wrapped inside click?

Thanks
