I am having a problem with a list value that is empty. I have a list of definitions called mainList. the 5th value in the list doesn't have anything in it. In this case, the values are definitions; also, in this case just the word cheese is defined. Here is my output to the console:


5. a sprawling,weedy plant having small lavender or white flowers and round, flat, segmented fruits thought to resemble little wheels of cheese. 6. 7. an ingot or billet made into a convex, circular form by blows at the ends.


I've made it so where the numbers, the period, and two spaces follow that, then the definition. However, as you can see in 6, there is nothing. Here is the code to print all this:

n=0

for x in mainList:
    if mainList[n] == "":
        print "Error on this definition"
    else:
        print str(n+1)+".  "+str(mainList[n])
    n=n+1

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.

My guess is that your 'empty' value is something like ' ', which is not equal to ''. Change str to repr and see better what item 6 is.
