For efficiency I suggest to initialize the mapping with dict.fromkeys(range(128), 'x') rather of an empty dict.

It is also possible to use regular expressions:

_trans = re.compile(r'''[^(){}\[]"'\\\n#]+''')
code = _trans.sub('x', code)
code = code.replace('{', '(')
code = code.replace('}', ')')
code = code.replace('[', '(')
code = code.replace(']', '(')
code = code.replace('\nx', '\n')

I didn't check what way is more efficient.
