"Where does a wise man hide a leaf? In the forest.
But what does he do if there is no forest? ... He grows a forest to hide it in."
-- Gilbert Keith Chesterton
Ever tried to send a secret message to someone without using the postal service? You could use newspapers to tell your secret. Even if someone finds your message, it's easy to brush...
You are given a chunk of text. Gather all capital letters in one word in the order that they appear in the text.
For example: text = "ow are you? h, ok. ow or ower? hhh.", if we collect all of the capital letters, we get the message "HELLO".
A text as a string (unicode).
The secret message as a string or an empty string.
find_message(('How are you? Eh, ok. Low or Lower? ' 'Ohhh.')) == 'HELLO' find_message('hello world!') == '' find_message('HELLO WORLD!!!') == 'HELLOWORLD'
This is a simple exercise in working with strings: iterate, recognize and concatenate.
0 < len(text) ≤ 1000
all(ch in string.printable for ch in text)
