In the program below, which two variables have the same scope?

def usernameMaker (strFirst, strLast):
return strFirst + strLast[0]


def passwordMaker (strA, numC):
answer = dogName[0:3]
return answer + str(numC)

# the main part of your program that calls the function
username = usernameMaker ('Chris', 'Smith')
dogName = 'Sammy'
favoriteNumber = 7
password = passwordMaker (dogName,favoriteNumber)
