Morse Code Encryption/Decryption Program

Develop and test a Python program that allows a user to open a text file containing a simple message using only the (uppercase) letters A . . . Z, and saves a Morse code version of the message, that is, containing only the characters dash (-), dot (.). In the encoded version, put the encoding of each character on its own line in the text file. Use a blank line to indicate the end of a word, and two blank lines to indicate the end of a sentence. Your program should be able to both convert an English message file into Morse code, and a Morse code file into English. The Morse code for each letter is given below.

. N - . B o -.- P .--. D E R ... G .... -- .... T H .... U 1 .. V w --- ... Y M N
