Entry

Entry widgets are simple one-line text widgets. They do not support tags, marks, or embedded windows. The indexing syntax is consequently simpler:

number

Index into its contents, starting from 0.

end

End of the text.

insert

The position immediately after the insertion cursor.

sel . first, sel.last

Indicates the first and last character of the selection range.

The index argument for all methods in Table A.7 accepts any of the styles described above.
