IF Statements that will call different functions with argparse

问题

I really dont think what I'm asking for is difficult but I can't find anything that helps without it talking about integers or different kind of arguments. I just want to call different functions using argparse. I want to call either the SHC updater, HCM, or Cloud. Right now it does all 3.

I need if statements.

if __name__ == "__main__":

    def _msg(updated):
        return "was updated" if updated else "already up-to-date"

    HCM_Updater = HCM()
    updated = HCM_Updater.update()
    print("HCM {}.\n".format(_msg(updated)))

    SHC_Updater = SHC()
    updated = SHC_Updater.update()
    print("SHC {}.\n".format(_msg(updated)))

    Cloud_Updater = Cloud()
    updated = Cloud_Updater.update()
    print("Cloud {}.\n".format(_msg(updated)))
