What operator is used for string concatenation in Python?

In Python, the operator used for string concatenation is the plus sign (+). This operator allows you to join two or more strings together into a single string. For example, if you have two strings, "Hello" and "World", using the concatenation operator like this: "Hello" + " " + "World" would result in the string "Hello World".

The plus operator is specifically designed for this purpose in Python, which is why it’s essential for creating combined textual outputs. Other operators, such as the multiplication operator (*) and subtraction or division operators (- and /), do not serve the purpose of concatenating strings and are therefore not appropriate in this context.
