What does using the '+' operator in Python specifically do?

The use of the '+' operator in Python predominantly serves the purpose of concatenating strings. When two strings are combined using this operator, they are joined together to form a single string. For example, if you have two strings, "Hello" and "World," using the '+' operator results in "HelloWorld." This operator interprets the operands as strings and performs the concatenation, demonstrating how it allows for the creation of new strings by merging existing ones.

While the '+' operator also adds numeric values, the question specifically asks about its usage, and concatenation of strings is a key feature of this operator in Python, especially in scenarios involving string manipulation and formatting. This ability to join strings is fundamental in many programming tasks, such as constructing messages or assembling data for output.
