  Output

Either of two codes consisting of variously spaced dots and dashes or long and short sounds used for transmitting messages by audible or visual signals. A system of sending messages that uses long and short sounds, flashes of light, or marks to represent letters and numbers. A system of sending messages that uses long and short sounds or dots and dashes to represent letters and numbers.

The International Morse Code has, except for some minor changes in 1938, remained the same since its inception. (The American telegraph industry never abandoned the original Morse Code, and so its use continued until the spread of teleprinters in the 1920s and ’30s.) International Morse Code was used in World War II and in the Korean and Vietnam wars. It was used heavily by the shipping industry and for the safety of the seas up until the early 1990s. Although amateur radio made up only a small part of Morse Code usage, it did prepare many hundreds of operators for military duty in communications. In the early 2000s most countries had dropped the ability to decipher Morse Code from the requirements for obtaining an amateur radio license.

Morse code has been in use for more than 160 years — longer than any other electrical coding system. What is called Morse code today is actually somewhat different from what was originally developed by Vail and Morse. The Modern International Morse code, or continental code, was created by Friedrich Clemens Gerke in 1848 and initially used for telegraphy between Hamburg and Cuxhaven in Germany. Gerke changed nearly half of the alphabet and all of the numerals, providing the foundation for the modern form of the code. After some minor changes, International Morse Code was standardized at the International Telegraphy Congress in 1865 in Paris and was later made the standard by the International Telecommunication Union (ITU). Morse's original code specification, largely limited to use in the United States and Canada, became known as American Morse code or "railroad code". American Morse code is now seldom used except in historical re-enactments.

We have built a python program to translate Morse Code here is the program ..
