I am new to spaCy. I added this post for documentation and make it simple for new starters as me.
import spacy
nlp = spacy.load('en')
doc = nlp(u'KEEP CALM because TOGETHER We Rock !')
for word in doc:
print(word.text, word.lemma, word.lemma_, word.tag, word.tag_, word.pos, word.pos_)
print(word.orth_)
I am looking to understand what the meaning of orth, lemma, tag and pos ? This code print out the values also what the different between print(word) vs print(word.orth_)

1) When you print word, you basically print Token class from spacy which is set to print out string from the class. You can see more here. So it's different from printing out word.orth_ or word.text where these will print out string directly.
2) I'm not sure about word.orth_, seems like it is word.text for most cases. For word.lemma_, it's the lemmatize of the given word e.g. is, am, are will map to be in word.lemma_.
