regional.py

"""
Usage: python3 regional.py list of words
Prints a representation of the words as Regional Identifiers, and copies the output directly to keyboard for you
This is because some terminals think that zero width spaces are silly.

Currently supports: A-Z
Requires: Python 3

Now less complex, thanks @bmispelon!

def regional_indicator(letter):
    # Try and see if there's a REGIONAL INDICATOR SYMBOL for our letter.
    try:
        return unicodedata.lookup('REGIONAL INDICATOR SYMBOL LETTER %s' % letter.upper());
    except KeyError:
        return letter

xerox.copy(output)

print("Copied to Clipboard: %s" % output)

A few more silly comments:

The list comprehension's brackets '[ ]' inside the join() can be removed to turn it into a generator expression, which is faster and does the same thing.

The code currently sandwiches Zero-Width Spaces between regional indicators and spaces between words, which isn't necessary. Can be fixed by joining with U+200B before joining with " ".

You can even one-line it if you're feeling particularly evil. Something like

`output = "\u200B".join([unicodedata.lookup('REGIONAL INDICATOR SYMBOL LETTER %s' % x.upper()) if 65 <= ord(x.upper()) <= 90 else ' ' for x in ' '.join(sys.argv[1:])])`

should work 😇
