If all you want to do is return the index of b inside of a, if b is present, and so something else if it is not, try this : -

a = ["one", "two", "three", "four"]
b = "three"
try:
    print a.index(b) #if inside the function, use return
except:
    #do something2

As other experts said, I would highly recommend you try it with your own Python 2.x/3.x environment.

If you for some reason don't have it in hand, try some online IDEs, for example https://ideone.com/
