Solve the following python programming problem given the following code:
def _makefile(self, ext, args, kwargs) : 
    items = list (kwargs.items ()) 
    if args : 
        source = (py.builtin._totext ('
').join (map (py.builtin._totext, args)) + py.builtin._totext ('
')) 
        basename = self.request.function.__name__ 
        items.insert (0, (basename, source)) 
ret = None 
    for (name, value) in items : 
        p = self.tmpdir.join (name).new (ext = ext) 
        source = Source (source_unicode) 
        def my_totext(s, encoding = 'utf-8') : 
            if py.builtin._isbytes (s) : 
                s = py.builtin._totext (s, encoding = encoding) 
return s 
source_unicode = '
'.join ([my_totext (line) for line in source.lines]) 
        source = py.builtin._totext (source_unicode) 
        content = source.strip ().encode ('utf-8') 
        p.write (content, 'wb') 
        if (ret is None) : 
            ret = p 
return ret
