# In a while loop I recommend to NOT end loops using the
# conditional test of == but instead use >, <, >= or <= or !=.
# In a complex while loop the exit condition may be skipped
# by mistake and you'll loop forever.
# In while loops I get less bugs by putting the incrementor as
# the last statement in the while block;
# this helps follow precedence like range(7) is - zero to 6
# as well as index 0 in a list is the first item. However
# while index: where index == 0 will exit the loop before
# it even starts as 0 == False (0 is not False but equals False)
# Use the while loop for looping an undetermined number of
# iterations or conditional iterations.
# Use for loops for an explicid number of iterations.

# I'm guessing the chapter's test is to see if you remember the for
loop.
# start using print() to get into a good habit for Python 3.0+
# I haven't seen the book but often one part of while that is
# left off in tutorials is the "else" statement.
while condition:
"block"
else:
"block"
# you can use else for when the condition never happens.
