[Shashidhar Paragonda]

Dear Noufal,

Thanks for your reply
 I did in this way is it efficient way to achieve the same requirement

        all_lines_in_file = open("file.txt", "r").readlines()

        >>     for line in range(0, len(all_lines_in_file)-1):
        >>     if "resultsToPDFFile" in all_lines_in_file[line]:
        >>           if
all_lines_in_file[line].split('->')[1].split(')')[0].split("'")[1].strip()
== 'true':
        >>                 self.cnc_parameters['PDF'] = "ON"
        >>             elif "resultToExportToPDFDialog" in
all_lines_in_file[line]:
        >>                 if
all_lines_in_file[line+1].split(')')[0].split('#')[1] == 'off':
        >>                     self.cnc_parameters['PDF'] = "OFF"
        >>                 else:
        >>                     self.cnc_parameters['PDF'] = "ASK"
