Which operator concatenates first name and last name in the example provided?

The operator that concatenates strings, such as a first name and a last name, is the plus sign (+). In Python, the plus operator is used with string operands to join them into one continuous string.

For example, if you have a first name and a last name stored in separate string variables, you can use the + operator to combine them, like this:

first_name = "John"

last_name = "Doe"

full_name = first_name + " " + last_name

In this snippet, the first name "John" and the last name "Doe" are concatenated with a space in between, resulting in the full name "John Doe". This behavior is specific to string objects in Python, allowing for seamless and straightforward concatenation of multiple string values. Other operators listed, such as the minus sign, colon, or asterisks, do not perform string concatenation in Python.
