Expensive Words

Each letter in a sentence is worth its position in the alphabet (i.e. a = 1, b = 2, c = 3, etc...). However, if a word is all in UPPERCASE, the value of that word is doubled.

Create a function which returns the value of a sentence.

get_sentence_value("abc ABC Abc") ➞ 24
# a = 1, b = 2, c = 3

# abc = 1 + 2 + 3 = 6
# ABC = (1+2+3) * 2 = 12 (ALL letters are in uppercase)
# Abc = 1 + 2 + 3 = 6 (NOT ALL letters are in uppercase)

# 6 + 12 + 6 = 24

Examples

get_sentence_value("HELLO world") ➞ 176

get_sentence_value("Innokodakademija is LEGENDARY") ➞ 251

get_sentence_value("Her seaside sea-shelling business is really booming!") ➞ 488

Notes

• Ignore spaces and punctuation.
• Remember that the value of a word isn't doubled unless all the letters in it are uppercase.
