I could indeed have addressed this problem with a list comprehension.
It escaped me at the time because the larger problem I was trying to
solve included removing data from a dictionary:
months =
sorted(list(dataDict.keys())) #Sort
months in ascending order

Just a quickie, is there a reason you can't use a list comprehension?
x = [i for i in x if i % 2]

In the past, when deleting items from a list, I looped through the
list in reverse to avoid accidentally deleting items I wanted to keep.
I tried something different today, and, to my surprise, was able to
delete items correctly, regardless of the direction in which I looped,
in both Python 3.2.2.

Do you really need to remove them? Removing items from a list tends to be
slow. The more Pythonic approach is to create a new list:
>>> a = [1,2,3,4,5,6,7]
>>> b = a[1::2] # o
Is there a quick way to simultaneously pop multiple items from a list?
For instance if i had the list a = [1,2,3,4,5,6,7] and I wanted to
return every odd index into a new list, my output would be new_list =
[2,4,6] or similarly if I wanted to return each index that was one
away from the midpoint i
