Description Workspace Description Write a function longest_line_length that takes a string file_name as an argument and returns the length of the longest line in the file. The length of the line is just the number of characters in it (whitespace included). If the file is empty, the function should return None. Consider a file song.txt with the contents: TEXT 1 Row, row, row your boat 2 Gently down the stream 3 Merrily, merrily, merrily, merril 4 Life is but a dream! longest_line_length('song.txt') should return 35 (including whitespace and newline characters). Use the len function to count the numbers of characters in a line including whitespace and newline characters.
