hopefully (2) easy questions (region.focus & code consolidation)

I am currently reading up on Python Loops...
https://www.geeksforgeeks.org/loops-in-python/
Just need to wrap my head around how to implement / structure

at 1---
App.open("D:\\Program Files\\Nox\\bin\\Nox.exe")
sleep(15)
App.focus("NoxPlayer")
reg = App.focusedWindow()

or
app = App("D:\\Program Files\\Nox\\bin\\Nox.exe")
app.open(15) # does the focus as well
reg = app.window(0)

... the docs are showing ;-)

your problem surely is, that you have too many waits in your code, that are absolute.
example from above:
App.open("D:\\Program Files\\Nox\\bin\\Nox.exe")
sleep(15)
App.focus("NoxPlayer")
... sleep(15) waits 15 seconds, no matter what really happens
better:
app = App("D:\\Program Files\\Nox\\bin\\Nox.exe")
app.open(15) # does the focus as well
reg = app.window(0)
... open waits MAX. 15 seconds for the app to open. script continues at the moment, the app is open (might be after 3 seconds)

... same goes for image searches
instead of:
click(whatEver)
wait(5)

better:
click(whatEver)
wait(forSomeImage, 5) # might continue after 1 second if image is there

Thank You RaiMan - I appreciate your patience & response. I will make the suggested corrections

for second question...to structure a loop?

My normal sequence is
Run Script (scheduled task)
Load Nox
Load app
  do stuff to:
    Select Google ID
      do stuff to:
        Select Account
          perform action on account
           do stuff to:
             Select next account (1-5 possible)
Exit app inside Nox
Clear app data (via shell script shortcut)
Load app
  do stuff to:
    Select (next) Google ID (8 possible)
      repeat for all 25 accounts
Exit Nox
Exit Script

So would this be a for loop with the "select portion" as a set of variables? (my terminology is probably wrong, hopefully you can understand what I am trying to ask)

What I really want to accomplish is (end goal) create 4-5 scripts that "perform different action(s) on account" based on the initial building blocks of being able to load and switch accounts

clarification / correction
this:
        Select Account
          perform action on account
           do stuff to:
             Select next account (1-5 possible)
Exit app inside Nox

should be:
        Select Account
          perform action on account
           do stuff to:
             Select next account (1-5 possible)
               perform action on account
Exit app inside Nox

...or am I still thinking about this wrong (structure) and I should be "storing" the do stuff / action and "calling" it when needed?

nOOb - thanks!

thank you - my knowledge now surpasses my skill - so I will go experiment and practice for a bit
I "get" the function part, so I will start there, then work towards utilizing a for loop

Thanks RaiMan, that solved my question.
