Module with application script

The scripts convert1.py and convert2.py load and dump data - this functionality can be reproduced by an application script using convert3
The application script can be included in the module: 
if __name__ == '__main__':
    import sys
    try:     
        infilename = sys.argv[1]
    except:  
        usage = 'Usage: %s infile' % sys.argv[0]
        print usage; sys.exit(1)
    y, dt = load_data(infilename)
    dump_data(y, dt)
If the module file is run as a script, the if test is true and the application script is run
If the module is imported in a script, the if test is false and no statements are executed
