Python String and List Tasks | Dataford Interview Questions

The Hp Iq QA automation pipeline receives a list of result identifiers and a diagnostic string. Implement a function that removes duplicate identifiers while preserving their first-seen order, then counts the vowels in the diagnostic string.

Return both results in a dictionary with keys unique_items and vowel_count.

Formal Specification

Implement process_results(items, text).

items is a list containing integers or strings. Values are compared using normal Python equality.
text is a string containing ASCII letters, spaces, digits, and punctuation.
Duplicate values in items must appear only once, at their first index.
Count a, e, i, o, and u regardless of letter case. The letter y is not a vowel, and accented characters are outside the input domain.
Return a dictionary: {"unique_items": list, "vowel_count": int}.

Constraints

0 <= len(items) <= 100,000
0 <= len(text) <= 100,000
Each item is an integer or string and is hashable
Only ASCII vowels a, e, i, o, and u are counted
The letter y is not considered a vowel
