 raise TypeError("Need a valid target to patch. You supplied: %r" %
 (target,))


Suggested change
raiseTypeError("Need a valid target to patch. You supplied: %r"%
(target,))
raiseTypeError(f"Need a valid target to patch. You supplied: {target}")
since there is a change of nearby lines anyway. Plus, "b'%r' is deprecated, but will not be removed during the 3.x series" in the docs.

Should be {target!r} I suppose?

Ah, yes. I was optimistic seeing string-only nature of target:
cpython/Lib/unittest/mock.py
Line 1693 in 461e59e
`target` should be a string in the form `'package.module.ClassName'`. The
Like, once it was an object requiring some special formatting but now it's just a string. However, I forgot that %r additionally escapes non-ascii code points.

Right, also this bpo is about the case where the error is that you passed in some non-string object.
