How do you split a string into individual characters?

So I am doing this challenge:

Question:

It’s 1868 and you’ve just bought a telegraph key so you can transmit messages in Morse code directly to your friend using a personal telegraph line. We’ve given you a file morsecode.txt which translates from any character (except a space) to its code. When a message is written in Morse code, characters are separated by spaces, while actual spaces are written as slash (/) in coded messages.

I want to split the input string into individual characters and verify it with the code in the file.

my code:

data = {}
with open('morsecode.txt') as f:
  for line in f:
    key, value = line.split()
    data[key] = (value)
  
code = input('Message: ').lower()

The desired output:

I can’t share the text file in stackoverflow for some reason

here’s the text in the file:

A .-

B -…

C -.-.

D -..

E .

F ..-.

G –.

H ….

I ..

Answer

Assuming data dictionary is getting updated when you read from the text file, you can do the following:

code = input('Message: ').lower()
new_string = ' '.join(data[letter] for letter in code)

.join takes an iterable as an argument. You can fetch the particular value from the dictionary and pass them in join
