Python: Looking for ways to improve code on note taking script

Question

I have only dabbled in coding before. Made this notepad programme to use while at work taking calls. Any advise on how this could be improved would be appreciated. I know there has to be a better way of doing the functions. I tried making it so the text it is pasting in to the text field was dealt with by function arguments, watched a few videos and read the documentation but couldn't get it to work. Any and all advice appreciated. thank you.

One code smell you can remove is not using lambda when adding a command, as it serves no real purpose.

command= lambda: save_text()

I'm guessing you are using lambda so the the function won't be called when executing the script. However the Button widget does this by default as long as you point to the function object, without calling it.

command=save_text
