Could this please be answered for Python?

An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. Append a period (.) after each letter in the acronym. If a word begins with a lower case letter, don't include that letter in the acronym. Assume the input has at least one upper case letter. Ex: If the input is: Institute of Electrical and Electronics Engineers the output is: IEEE. Ex: If the input is: the output is: A. M. The letters ACHINERY in MACHINERY don't start a word, so those letters are omitted. Hint: Use isupper() to check if a letter is upper case
