Hi, I am new to Python + CGI. my application is to searching multiple file using parallel processing. each process return the output any time. I want to process that ourput and place in HTML table. here is mycode.
what I abserved the html table is updating proper if print before "if __name__ == '__main__':".
Can you point me what is the mistake in the script?
