Please, help me I'm a novice programmer.
I trying to make an array with random numbers and print the maximum, minimum, and average values.

I wish to identify and then create a list in python all stocks (Capitalized Letters) mentioned here..

The problem I have a large text doc with many areas containing 2 3 or 4 Capitalised letters however i only want to get the ones that precede a paragraph ending (stocks-to-watcch are in the following paragraph):

i.e SE, SAM, PYPL, LAD, GLOB .....etc

Not sure if non capturing groups is the way to go or whether I can do look behinds.. if I do non capturing groups to I was thinking something like this would work but it doesn't... any help greatly appreciated

I have a dataframe like this:

I'm new to tkinter so please bare with me (Python 3.8.5/Tkinter 8.6 sample code at the end of the post - There is also an Edited Version)

I'm trying to change & keep highlighted the button-bg while the user interacts with the menu, and reset it only after the menu goes away.

This picture shows what I mean (default behavior on the left, mine on the right)

I've researched and tried several things and I've managed to make it partially work. It's not shown in the pic, but additionally the button-bg gets reset when the user closes the menu by selecting an option. However, I cannot detect when the menu gets closed via a click outside the menu.

What I'm doing in the code below, is setting the button's activebackground upon creation and also forcing it as bg in the postcommand option. Then I add an on-click callback to all menu-items (via their command option) which resets the button's bg. Apparently, the command callback overwrites their default one, so I'm additionally updating manually the StringVar() of the OptionMenu.

I have so many unanswered questions, but the main one is how can I catch the case where the menu gets closed without an option being clicked, so I can reset the button-bg? Everything else works as intended.

And a few more questions if I may:

1. Can we obtain the actual widget object of a menu-item? None of the Menu widget methods seem to return a menu-item widget (it could save me the overriding of the default callback, and thus updating manually the StringVar() since I could

menuitem.bind("", callback, add="+")

instead of

menu.entryconfigure(i, command=callback)

1. Is there a way of passing the event object to the callback when using the command option?

2. Do the "" and "" events even work on om['menu']? They didn't in my tries on Windows (btw same goes for the .unpost() method)

Thanks in advance for any replies!

Here comes the sample code
