That is a colloquialism: - my computer does things - my program[me] does stuff The "stuff" is something of a euphemism. In our profession, I would suggest it is used to avoid detail, eg as a 'signal' to a non-IT person that a more detailed answer would likely bore, or 'go over your head'. In PM-circles we identify the beginning and end of a project - the rest of the project plan 'stuff', is known as 'the miracle that happens in the middle'. Want more detail? Do we have more detail? What do I know? If a dog owner said: "my dog does things" it would again be a euphemism, but in this case employed to avoid saying something distasteful, ie that the puppy is not (yet) house-trained. That said, I suspect if you tried to use it in an English (language/literature) essay, the teacher/prof would take exception to such informality, and demand a 'better' noun! Believe it or not, my second trainee-discussion of the day included a question similarly-worded: 'why does the computer/interpreter/run-time do these things?'. Rather than 'literature', I taught this guy one of my favorite excursions into the world of poetry (the specific type of poetic stuff is "doggerel"): I really hate this dumb* machine, I wish that they would sell it. It never does quite what I want, but only what I tell it! * you might regard this word as a euphemism for another Upon which note, and your observation that I am no English-major, it's probably time we went to do things... -- Regards =dn -- https://mail.python.org/mailman/listinfo/python-list

My intent is to locate the line containing "Total amount", skip the next

Thanks for any insigths --
The first observation is that the two for loops are essentially
identical, so why not condense?
However, what is described may be calling for a solution called "a
finite state machine":
state 1: ignore unwanted data, until "Total amount" is found
state 2: skip blank line
state 3: grab the Euro value, and return to state 1
Being a simple-boy, I would avoid any reg-ex, because:
myline[ :11 ] == "Total amount"
is easier (and faster). Similarly, there is no need for rstrip-ping
except at "state 3" (unless there are particular rules for the
formatting of the total).
Another thought is that the problem is being visualised as a series of
lines and this may complicate things. If instead, a "buffer" or indeed
the entire file, could be read at a time (which is current code, per
first comment above), the string.find() method could be employed
(replacing "state 1"), and then (implicit assumption about spacing here)
"state 2" becomes a matter of moving a few characters 'along', before
grabbing the total; rinse and repeat...

I tried to call win32gui.SetCapture without any effect. Does anyone have an idea how to handle this? Thank you very much, Are you asking to be able to start a Python application in one window, which will control the mouse and keyboard in other concurrent applications' windows? I don't use MS-Windows, but don't think this is possible (under any OpSys). As you say "and probably keyboard": imagine typing and having the text appear in every open window/application? If you don't want that, how do you indicate which one should accept the input? Answer: "focus" = the 'target' for any typing is the application/window which currently has focus. Extending those thoughts to the mouse doesn't quite ring-true, because I'm currently in 'this' window writing an email message, yet the mouse will cheerfully scroll the window 'below'. Is that the sort of action you wish? In my experience, the Python application, including "mouse", only operates in "user space" and within the one window. If we can extend Python's power and dominion, I'll be interested to learn... Meantime, there are demo snippets which follow the mouse, printing its coordinates. Using one of those, what happens to the coordinates when the mouse is moved outside of the Python application's window? BTW you may like to take a look at PyAutoGUI, if only because it has been more recently updated. It may also help by bringing 'everything' under one import rather than the multiple packages (listed above): https://pypi.org/project/PyAutoGUI/ https://pyautogui.readthedocs.io/en/latest/mouse.html https://automatetheboringstuff.com/chapter18/ -- Regards =dn -- https://mail.python.org/mailman/listinfo/python-list
