I think it is better to pass a list of arguments

# first_script.py 

def main(args=None):
    parser = optparse.OptionParser()
    # add options
    options, positional_args = parser.parse_args(args) 
    # process

if __name__ == "__main__":
    # will read options from the command line
    # if module is invoked as a standalone script
    main() 

# second_script.py

import first_script
first_script.main(["-f", "--bar", "what", "you want"])

That way you don't have to deal with escaping spaces etc.
