Im making a program to parse morse code. The input is in string format. Here is an example:
Input = '/.- .-.. .---- ..-. -.- - ..--- -.-. .... .....'
Desired Output = ['/', '.-', '.-..', '.----', '..-.', '-.-', '-', '..---', '-.-.', '....', '.....']
The / represents a space in the text. I would like to split the forward slash off to its own element and not get rid of it. The spaces however I do want to get rid of. Doing an expression like re.split(' |/') gets rid of the forward slash. How should I go about doing this? Thanks in advance.
Linguistically non-sophisticated approach using itertools.groupby and a custom key function that distinguishes '/', ' ' and rest:
from itertools import groupby
s = '/.- .-.. .---- ..-. -.- - ..--- -.-. .... .....'
key = lambda c: c if c in ' /' else 'x'
[''.join(g) for k, g in groupby(s, key=key) if k != ' ']
# ['/', '.-', '.-..', '.----', '..-.', '-.-', '-', '..---', '-.-.', '....', '.....']
