Unfortunately, many (most?) tutorials for particular modules (and even
example code in the Python documentation itself) are all written
assuming that you do "from <module> import *".  It saves the tutorial
write a few keystrokes, but causes untold trouble for people who learn
incorrectly that "from <module> import *" is the proper way to do
things.
