Hello experts,
I am having trouble accessing the content of my list. 
my list content has 2-pair value with the exception of one which has single value. here is an example  ['a', 1, 'b', 1, 'c', 3, 'd']
 
I am unable to iterate through list to access invidual value pairs
 
I get an error message saying ' the list should more than 1 value pairs'. I guess because 'd' has no value. How do I solve this problem?
 
Your help would be much appreciated.
 
Thanks
Sammy
