Answer 1

When you write:

if x in a:

You are testing if x is item of the list a.
If you want to test equality with a particular item, you need to write:

if x == a[i]:

or even 'if x is a[i]'

... but when you write:

if x in a[i]:

this will work only if item a[i] is also a list (or more generally an iterable, ie: a list-like object).
In your case, your list only contain numbers, which are not 'iterable' ;)
