Function Details: upper

Description

Returns a copy of the string converted to uppercase.

Extended Description

upper is a Python string method that converts all characters to uppercase. Essential for text standardization, data processing, and case-insensitive comparisons. Partners with lower for case transformations and often used with title and capitalize in text formatting workflows. Works alongside strip for text cleanup and casefold for Unicode handling. swapcase offers complementary case switching functionality. The method is crucial for ensuring consistency in user inputs, database queries, and text normalization tasks. Creates a new string instance, preserving the original, making it safe for immutable string operations.
