use py2exe to generate a standalone exe file from python script

gen_exe.py

import sys
try:
    import py2exe
except:
    raw_input('Please install py2exe first...')
    sys.exit(-1)

from distutils.core import setup
import shutil

sys.argv.append('py2exe')

setup(
    options={
        'py2exe': {'bundle_files': 1, 'compressed': True}
    },
    console=[
        {'script': "my_program.py"}
    ],
    zipfile=None,
)

shutil.move('dist\\my_program.exe', '.\\my_program.exe')
shutil.rmtree('build')
shutil.rmtree('dist')

why this extra text is shown in exe file before actual execution?
