Python Capitalization Script | Dataford Interview Questions

As part of a QA automation utility for L&T Technology Services, normalize messages before comparing expected and actual output. Write a function that converts every alphabetic character in a string to uppercase.

Non-alphabetic characters, including spaces, digits, and punctuation, must remain unchanged and in the same positions. The function must return a new string and must not modify the original input.

Formal Specification

Implement uppercase_text(text), where text is a string. Return a string containing the uppercase version of every letter in text. An empty input is valid. For this problem, inputs contain printable ASCII characters, so letters are in the ranges a-z and A-Z.

You may use Python's standard string operations. Do not remove whitespace or other characters.

Constraints

0 <= len(text) <= 10^5
text contains printable ASCII characters
The output has the same length as the input
The original string must not be modified

Function Signature

def uppercase_text(text):
