Language/Type: Python dict collections
Author: Eric Roberts (on 2017/07/08)

Write a function named to_morse_code that converts strings into their Morse code equivalents. Morse code is a mapping from each character from A-Z to a sequence of dots and dashes. For example, the string "SOS" could be represented in Morse code as '... -= 1- ...'.

Your function accepts two parameters: a dictionary from one-letter strings to strings representing their Morse encodings, and a String of text to convert. Assume that the provided client code builds a dictionary from individual text characters to their Morse code equivalents. For example, the key 'A' maps to ".-" . Your function accepts such a map, and a string to be converted, and should prout the Morse code equivalent of the given string to the console.

For example, if the letter to Morse code map is stored in a variable called mapping, the call of to_morse_code(mapping, "SOS TITANIC") should print the following console output:

... -= 1- ... - .. - .- -. .. -.-.

Note that the string might contain some characters that are not A-Z letters (like spaces) just skip those characters. You may assume that the mapping passed contains a mapping for every letter from A-Z in uppercase. Do not modify the letter map that is passed in.

Function: Write a Python function as described, not a complete program.
