As the users will enter string in Entry box , we will offer matching options like Autocomplete by using one listbox and user can select any one option to fill the Entry box.
We will place the Listbox below the Entry widget and keep the ypad=0 so both widgets are placed one below the other.
We will change the Listbox background colour and active border colour same as window background colour to merge the layout of the Listbox with the window.
We will trigger and populate the listbox options by taking data from the source listbox , for this we will use one for loop to list all available options and use regular expression match method to get the strings ( options ) matching to the searched string.
Once the match() method returns true the element is added as option of the Listbox.
We can bind the Listbox selection to pass the selected option as input to Entry widget.
