# Step-1
Find the first letter in the words of the given string.
# Step-2
Join all the letters and print it as an abbreviation.

s = "national aeronautics and space administration"
s1 = s.split()
l = []
for i in s1:
    if(i != "and"):
        a = i[0]
        l.append(a)
b = "".join(l)
print(b.upper())    

* The given string is split to find the first letter in each word.

* The `split()` method splits a string into a list -- the default separator is whitespace.

* An empty list is taken to store all the first letters of the words in the given string.

* The `join()` method takes all items in an iterable and joins them into one string.

* Finally, the upper method is used to convert all the characters in the string to uppercase.
