Trying to test whether the index of a dictionary is even or odd

P: 2
Hello everyone,
First time poster. Been at python about 2 weeks now.

As part of a larger challenge (that I have mostly solved) I need to print every other keypair in a dictionary.

The way I thought about this was looping through the dictionary with an index method and then trying to use % to tell if it was even or odd. If it was odd I would just append it to a new variable.

I am having all kind of issues and getting cryptic error messages.

Here is the snippet I am playing around with, right now just trying to get the index to compare and make sure that works before I loop through the dictionary:

Expand|Select|Wrap|Line Numbers
  1. for a in letlist:
  2.     a = (letlist.index)
  3.     int(a)
  4.     if ((a % 2) != 0):
  5.         print (a)
  6.  
This is the error: TypeError: int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method'

I have tried several different permutations and get errors on all. It is almost as if I can't do anything with a because I used it somewhere else.

Any help appreciated
