Looping through a dictionary for every other value

[fad3r]

Hi,
I am trying to find every other value in a dictionary. This is my thought process:

01) Create a loop to go through the dictionary's index.
02) Use a if statement to run a test with % to see if the result is even or odd
03) If the result is not even then I will append this value to a new list.

Here is the code (just trying to see it print before I start appending

odd = ()
for a in (letlist.index):
    if ((a % 2) != 0):
        print (a)

Returned: for a in (letlist.index):
TypeError: 'builtin_function_or_method' object is not iterable

I then tried this

odd = ()
for a in (letlist):
    if ((a % 2) != 0):
        print (a)

Returned: if ((a % 2) != 0):
TypeError: not all arguments converted during string formatting

So then I tried this (trying to make it simpler)

odd = ()
for a in (letlist):
    a = letlist.index
    if (a % 2):
        print (a)

That returned: if (a % 2):
TypeError: unsupported operand type(s) for %: 'builtin_function_or_method' and 'int'

Not sure what i am doing wrong. Is the logic that I wrote in how to solve the problem right? If so what is wrong with my implementation of it?

Thanks.
