Create a function to generate initials from a two-word input name.
The key understanding in handling strings is critical in Python. Build a function that accepts a two-word name and outputs a string representing the initials of the name, separated by a period and formatted in uppercase. ### Parameters - `fullname`: This is a string representing a complete name, consisting of two words separated by a space. Each word starts with an upper-case letter followed by lower-case letters. ### Return Value - The function should return a string that represents the abbreviated initials of the supplied `fullname`, separated with a period. ### Examples ```python # The initials of Sam and Harris are S and H respectively abbreviate("Sam Harris") # Should return: "S.H" # The initials of Patrick and Feeney are P and F respectively abbreviate("Patrick Feeney") # Should return: "P.F" # The initials of Similar and Kata are S and K respectively abbreviate("Similar Kata") # Should return: "S.K" ```
