Solve the following python programming problem given the following code:
def camelize(s) : 
    '
    >>> camelize("ABC DEF")
    \'Abc Def\'
    >>> camelize("ABC def")
    \'Abc def\'
    >>> camelize("eID")
    \'eID\'

    ' 
    def f(k) : 
        if (k.upper () != k) : 
            return k 
return (k [0].upper () + k [1 :].lower ()) 
return ' '.join ([f (s) for k in s.split ()]) 

    
    

    Fix the buggy line: return ' '.join ([f (s) for k in s.split ()])
