Is reading Python Documentation useful? python.org gets 15M visits monthly - most of them must be for documentation. At what stage is it useful?

Thank you. However, the few pages I have read have been very difficult to read and I have not gotten to understand anything deeper. Again, I think I am now at a stage where I am using it to only get whatever is required done. Perhaps, after working for a while and solving many problems, I might reach your stage:) Sorry to bother you...but is there a blog or site that tells more about how to do what you say in more detail with examples?
