import re

def is_numeric(s):
    """
    Check if a string is a numeric value.

    :param str s: String to be checked
    :return bool: True if string is a numeric value, False otherwise
    """
    try:
        float(s)
        return True
    except ValueError:
        return False

# Enter the string
s = "123"

# Calling the function
print((is_numeric(s)))

#Example Output

#Remember to inspect code for bugs.
