New submission from Bob Alexander:
Here is simple example of failure to parse arguments that should parse OK. In
the following little program, the second from last line contains an aargument
sequence that parses OK, but the last line should but doesn't.
import argparse
ap = argparse.ArgumentParser()
ap.add_argument("--option", action="store_true")
ap.add_argument("arg_1")
ap.add_argument("arg_2", nargs="?")
print("test 1:", ap.parse_args(["abc", "mmm", "--option"]))
print("test 2:", ap.parse_args(["abc", "--option", "mmm"]))
