Correct Answer: upper()

The upper() string method returns a new string with all characters in uppercase.

Correct Answer: f"Hello {name}"

An f-string prefixes the string with f and embeds expressions in braces, such as f'Hello {name}'.

Correct Answer: split()

The split() string method divides a string into a list of substrings using a specified delimiter.

Correct Answer: join()

The join() method concatenates the elements of a list into a single string, using the calling string as separator.

The strip() string method returns a copy with leading and trailing whitespace removed.

Correct Answer: Reads a line of text from the user

The input() function pauses execution to read a line of text entered by the user, returning it as a string.

The == operator tests whether two values are equal. A single = performs assignment.
