I not surprised to see basic questions like "How to get length of a string in Python...?". Even people can easily find the answer inside the documentation, and it's pretty straightforward for other people googling the question to have the question/answer on Stack Overflow.As a consequence, since it helps lots of users, there are lots of +1 on these questions.
+1 on these questions give reputation points to the author.
Is it really fair to give so many reputation points to someone that just didn't read the documentation and asked this kind of question (even the question itself is useful)?
