how to use .format?

Question

Write a function that takes 3 strings - first name, last name and middle initial. Return one string that has the person’s full name. Make sure that the first letter of each name is capitalized (.title()) and then return the string. Use the .format() string function in the return statement.

Answer 1

The .format() string function uses placeholders, e.g. {0} for the first value, to indicate where to put the values provided to the format function. You put together the string with the placeholder(s) and the literal text that you want and then you call the format function on it to provide the values for the placeholders. Here is an example:

"The first one is {0} and the second one is {1}.".format(3, 17)

This will give back the string:

'The first one is 3 and the second one is 17.'

Answer 2

Here is a resource I found on using the format method: https://www.w3schools.com/python/ref_string_format.asp

this prompt seems like a one-liner.

I will write something similar, and you should be able to go off this to get your answer

def join_two_strings(foo, bar):

return "{0} {1}".format(foo,bar)
