Need help describing and understanding some python code

Question

I would really appreciate if someone could help me understand each line of code in this program. Thanks

sentence = "ASK NOT WHAT YOUR COUNTRY CAN DO FOR YOU ASK WHAT YOU CAN DO FOR YOUR COUNTRY"
s = sentence.split() 
another = [0] 

 print(sentence)
for count, x in enumerate(s): 
    if s.count(x) < 2:
        another.append(max(another) + 1)
    else:
        another.append(s.index(x) +1)
another.pop(0) 

print(another)

Would you mind to take a Python manual and read a little bit? — Psytho, Nov 17 '16 at 08:27
use `print()` after every line and print variables and you see what this functions do. — furas, Nov 17 '16 at 08:28
