From that big list, the following are the ones that would need to be fixed or investigated for Python 3 conversion project:

W1651 deprecated-itertools-function
Message
'Accessing a deprecated function on the itertools module'

Description
Used when accessing a function on itertools that has been removed in Python 3.

W1620 dict-iter-method
Message
'Calling a dict.iter*() method'

Description
Used for calls to dict.iterkeys(), itervalues() or iteritems() (Python 3 lacks these methods)

W1633 round-builtin
Message
'round built-in referenced'

Description
Used when the round built-in is referenced (backwards-incompatible semantics in Python 3)

W1619 old-division
Message
'division w/o future statement'

Description
Used for non-floor division w/o a float literal or from future import division (Python 3 returns a float for int division unconditionally)

W1637 zip-builtin-not-iterating
Message
'zip built-in referenced when not iterating'

Description
Used when the zip built-in is referenced in a non-iterating context (returns an iterator in Python 3)

W1636 map-builtin-not-iterating
Message
'map built-in referenced when not iterating'

Description
Used when the map built-in is referenced in a non-iterating context (returns an iterator in Python 3)
