Answer:
The correct code is:
def username (strFirst, strLast):
return strFirst[O] + strLast
answer = username ('Joann', 'Doe')
print (answer)
Explanation:
The given code illustrates the use of functions.
i.e passing values to a function and retrieving values from it
So, first: We start with the def statement
def username (strFirst, strLast): ----> This defines the function
Then the return statement
return strFirst[O] + strLast --- > This passes value to the main
Next, is the main function of the program which is:
answer = username ('Joann', 'Doe') ---> This passes values to the username function
print (answer) ---> This prints the returned value from the function
