Perhaps it’s the best if we assume that we had to do it this way, but can’t we just do a qemu_io_cmd = f'qemu-io {drive} "break {event} bp_{drive}"' self.qmp('human-monitor-command', command_line=qemu_io_cmd) ?

I didn't like the idea of iotests using a newer version of python than our build system, but my concern was not shared, so we get to use f-strings for non-buildtime tools. End of support for Python 3.5 will be 2020-09-13; so we'll get to use f-strings everywhere else soon, too. --js
