So i want to the stanford parser and using the lexparser.csh to parse this line of text . But when i run this piece of code i am a getting the output of the default of text. The actual text given in is not being parsed. So am i using pipes the right way ?And i've seen in a lot of examples - a '-' is used along with the command . Why is that being used ? Cos when i use that the script just stalls at sub.stdout.readline()
You may need to call flush()
on sub.stdin
after writing.
