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. if a word begins with a lower case letter, don't include that letter in the acronym. assume there will be at least one upper case letter in the input.

text = input("enter text: ")  

acronym = ' '

for c in text:

   if c.isupper():

       acronym += c

list(acronym)

print('.'.join(acronym))

Explanation:

The programming language used is Python.

Step 1:

text = input("enter text: ")  

acronym = ' '

The program prompts the user to enter a text and then we declare a variable that will hold a string called acronym.

There are two variables here the "text" and the "acronym".

Step 2:

for c in text:

   if c.isupper():

       acronym += c

The for loop here looks for any character i.e every letter in the text from the first to the last.

The if statement checks if that character is a upper case i.e (A-Z). if it is upper case it takes that character/letter and stores it in the string variable acronym which we declared in step 1.

Note: at this point you already have your acronym but it is not separated by a dot (.) i.e Greg Fisher would result in GF not G.F.

In order to achieve this step 3 and 4 is needed.

Step 3:

list(acronym)

The list function here breaks up every letter in the word and places them in a list. using the Greg Fisher example, you now have [G, F] not GF.

Step 4:

print(' .'.join(acronym))

This step Joins the list together again   ' .'  .join(acronym) but this time a dot(.) is used as the separator  and [G,F] now becomes GF.
