Here is a Python program to check if it is a string or not

import re

def is_string(s):
    """
    Check if it is a string or not.

    :param s: The string.
    :return: True if it is a string, False otherwise.
    """
    return isinstance(s, str)

# Enter the string
string = "carnation"

# Calling the function
print((is_string(string)))

#Example Output
