Try something like this...
list = ['lkdfjsldk', None, '', '0', 'slfkjsdlfj', 'lsdgjdlfg', False, True]
for n, it in enumerate(list) :
if not it: print 'Error on this definition'
else: print '%d. %s' % (n+1, it)
Results:
1. lkdfjsldk
Error on this definition
Error on this definition
4. 0
5. slfkjsdlfj
6. lsdgjdlfg
Error on this definition
8. True

I've made it so where the numbers, the period, and two spaces follow that,

the code to print all this:

Now the two "" is where I need to figure out if it is empty. What is up
right now doesn't work; or at least doesn't give the desired result. So I
need to know how to write the if statement to make it work. This should be
simple, but I just don't know how to do it, never had this problem before.
