You can use concatenation instead of (or in addition to) formatting:

>>> "" + "foo"
'foo'
>>> "" + b"foo"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't convert 'bytes' object to str implicitly
>>> "" + 42
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't convert 'int' object to str implicitly

Regards

Antoine.
