Decoding

Q：
In the war against Skynet, humans are trying to pass messages to each other without the computers realising what’s happening.

To do this, they are using a simple code:

They read the words in reverse order
They only pay attention to the words in the message that start with an uppercase letter
So, something like:

BaSe fOO ThE AttAcK

contains the message:

attack the base

However, the computers have captured you and forced you to write a program so they can understand all the human messages (we won’t go into what terrible tortures you’ve undergone). Your program must work as follows:

code: soMe SuPPLies liKE Ice-cREAm aRe iMPORtant oNly tO THeir cReaTORS. tO DestroY thEm iS pOInTLess.
says: destroy their ice-cream supplies

Notice that, as well as extracting the message, we make every word lowercase so it’s easier to read.

A：

code = input("code: ")
list_code = code.split()
list_code.reverse()
words = ''
for word in list_code:
  if word[0].isupper() == True:
    words += word + " "
says = words.rstrip()
print("says:", says.lower())
