Thanks Stefano, that looks much better.

A more succinct way would be:
str(x).encode()
In fact the outer call to ‘bytes’ in 'bytes(str.encode(str(x)))' is a
no-op, and python strings are objects which have an ‘encode' method,
so no need call the class method ’str.encode’.
Another possible way is
f"{x:d}".encode()
or
"{:d}".format(x).encode()
which is more “defensive”, in the sense that the conversion fails if x
is not an integer. In fact “str(x)” is defined for almost any
imaginable object in python, and could return anything. Therefore it
is better to be a little more verbose, and be explicit on the fact
that here we are interested in a decimal integer.
Another variant, in which we accept a float value could be
f"{round(x):d}".encode()
or
f"{x:.0f}"
but possibilities are endless.
Bye and thank you for sharing.

I had a bit of trouble with this and thought it worth sharing the
solution.
With Python2 and pyownet I could use
owp.write('/settings/timeout/directory', 60)
but with Python3 that throws an error, TypeError: 'data' argument
must be binary. I can use
owp.write('/settings/timeout/directory', b'60')
but if I want to use a variable for the data the format which works is -
x = 60
owp.write('/settings/timeout/directory', bytes(str.encode(str(x))))
There may be other ways to do it but that works for me.
