Not seeking to advocate this particular option, but it would be
possible to make a single wrapper for all your functions to handle the
focus= parameter:
def focusable(func):
@functools.wraps(func)
def wrapper(*args,focus=None):
if focus: focus.activate()
return func(*args)
return wrapper
Then you just decorate all your functions with that:
def write(string):
# do something with the active window
