This is fragile to renaming; more robust is to use:
{{module_pyname}}
...and then compute it via:

import os
module_basename = os.path.basename(__file__)
module_pyname = os.path.splitext(module_basename)[0] + '.py'

(extension b/c otherwise might get .pyc on second run)

+
+const MediaQueryTokenizer::CodePoint MediaQueryTokenizer::codePoints[{array_size}] = {{
+{token_lines}
+}};
+const unsigned codePointsNumber = {array_size};
