You can make the Entry widget read-only:

     entry_widget['state'] = 'readonly'

The user will still be able to copy from it.

Alternatively, you can disable it:

     entry_widget['state'] = 'disabled'

The user won't be able to copy from it.

When updating the GUI, you'll need to make it writeable if you have it 
currently read-only or disabled:

     entry_widget['state'] = 'normal'
     :
     # Change the contents here.
     :
     entry_widget['state'] = 'readonly'
