How to select at the same time from two Tkinter Listbox?

Let us consider a situation for a particular system to keep selecting multiple files from a directory and, once copied in the clipboard, paste them into another directory. The idea of making multiple selections in ListBoxes can be implemented by using the exportselection property. The property prevents the selected options from losing while choosing an item from another ListBox. Thus, we can select multiple options from the ListBoxes. To configure a Listbox to behave like keep selection steady, we can make exportselection = False.

Example

#Import Tkinter library from tkinter import * #Create an instance of Tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x350") #Create ListBoxes listboxA=Listbox(win, exportselection=False) #Create listboxA listboxA.pack(padx=10,pady=10,fill=BOTH,expand=True) listboxB=Listbox(win,exportselection=False) #Create ListboxB listboxB.pack(padx=10,pady=10,fill=BOTH,expand=True) listboxA.insert(1, "1.Python") listboxA.insert(2, "2.Java") listboxA.insert(3, "3.C++") listboxA.insert(4, "4.Rust") listboxA.insert(5, "5.GoLang") listboxB.insert(1, "a.C#") listboxB.insert(2, "b.JavaScript") listboxB.insert(3, "c.R") listboxB.insert(4, "d.Php") listboxB.insert(5, "e.CoffeeScript") listboxB.insert(6, "f.Curl") win.mainloop()

Output

Running the above code will display a window that contains two listboxes. While making a selection, we can select multiple items from both listboxes.
