Description: bpo-26510 in 3.7.0a2 changed the behavior of argparse to make subparsers required by default, returning to the behavior of 2.7 and 3.2. The behavior was changed in 3.3 to be no longer required. While it might make more sense to have the default to required, compatibility with 3.3 through 3.6 is probably less disruptive than trying to reintroduce compatibility with 2.7 at this point. This change restores the 3.6 behavior. https://bugs.python.org/issue33109
