The 'argparse' module gives a parse error for integer arguments written in scientific notation. I would expect this to work, since integers can be constructed from literals in scientific notation.

Example (also attached):

import argparse
foo = int(1e3) # Works: foo = 1000
parser = argparse.ArgumentParser()
parser.add_argument( "--foo", type=int )
parser.parse_args( ["--foo=1e3"] )
# error: argument --foo: invalid int value: '1e3'
