Answer:
text = input("enter text: ")
print(text)
acronym = ''
for c in text:
if c.isupper():
acronym += c
list(acronym)
print('.'.join(acronym))
Step-by-step explanation:
The code above takes an input phrase, an empty string string "acronym" is created to hold the the acronym.
A FOR loop is used with an IF statement to check if any of the characters begin with an uppercase letter and adds it to the acronym string.
The acronym string is converted to a list so that each letter can be recombined using a dot(.) and finally the acronym is printed to the screen.
