# Returns the first character of the string str

def firstCharacter(str):

return str[:1]

# Returns the last character of a string str

def lastCharacter(str):

return str[-1:]

# Returns the string that results from removing the first

# and last characters from str

def middleCharacters(str):

return str[1:-1]

def isPalindrome(str):

# base case #1

# base case #2

pass
