I would like to know what punctuation mark need to be placed after the word like in the sentence below: Filter by genre shall display the list of genre like, Action. For example, I want to display current date and time as the following format: yyyymmddhhmmss How do I do that? It seems like most date format comes I'm just starting to use NLTK and I don't quite understand how to get a list of words from text. If I use nltk.word_tokenize(), I get a list of words and punctuation. Should there be a comma after you in the following sentence? If the afternoon works best for you, please let me know and I will try to adjust my schedule. I've been trying to get a specific regex working but I can't get it to do what I need. Basically, I want it to look for ROCKET. The regex should match ROCKET in upper.
