Practice: Initials

Lesson

Practice: Initials

This exercise combines split, indexing, upper, and a string accumulator.

Exercise

Define a function named initials with one parameter, full_name.
It returns the initials: the first letter of each word, uppercased, each followed by a period.

initials("Ada Lovelace") returns "A.L.". initials("grace brewster murray hopper") returns "G.B.M.H.". initials("Plato") returns "P.".

Run your code to see the output, then press Submit.

Hints

Split the name into words, then loop over the words.
For each word, add its first character (uppercased) and a period to the accumulator.

Tests

import unittest


class TestInitials(unittest.TestCase):
    def test_two_names(self):
        self.assertEqual(initials("Ada Lovelace"), "A.L.")

    def test_lowercase_names_are_uppercased(self):
        self.assertEqual(initials("grace brewster murray hopper"), "G.B.M.H.")

    def test_single_name(self):
        self.assertEqual(initials("Plato"), "P.")

Solution

def initials(full_name):
    result = ""
    for word in full_name.split():
        result += word[0].upper() + "."
    return result


print(initials("Ada Lovelace"))
print(initials("grace brewster murray hopper"))
