Valid Hex Code

Create a function that determines whether a string is a valid hex code.

A hex code must begin with a pound key # and is exactly 6 characters in length. Each character must be a digit from 0-9 or an alphabetic character from A-F. All alphabetic characters may be uppercase or lowercase.

Examples

is_valid_hex_code("#CD5C5C") ➞ True

is_valid_hex_code("#EAECEE") ➞ True

is_valid_hex_code("#eaecee") ➞ True

is_valid_hex_code("#CD5C58C") ➞ False
# Length exceeds 6

is_valid_hex_code("#CD5C5Z") ➞ False
# Not all alphabetic characters in A-F

is_valid_hex_code("#CD5C&C") ➞ False
# Contains unacceptable character

is_valid_hex_code("CD5C5C") ➞ False
# Missing #
