I have a small array in Python, and I need to get the 2nd element of that array, or a default value if it's not present. All the other languages (PHP, Perl, Javascript) I use have a simple null coallescing operator that makes it simple, but not Python. I got tired of writing it out every time to so I wrote a simple wrapper function:

x = [2,4,6]

# Get the 3rd item from x
y = arrayItem(2, x, -1) # 6
# Get the 8th (non-existent) item from x
y = arrayItem(7, x, -1) # -1

# Get an item from an array, or a default value if the array isn't big enough
def arrayItem(needle, haystack, default = None):
    if needle > (len(haystack) - 1):
        return default
    else:
        return haystack[needle]

If there is a better, simpler, built-in way I'm open to hearing it.
