# Python2.x Python Tkinter Text Box (Entry) [ Python GUI Programming](#) Python Tkinter Text Box (Entry) is used to allow users to input a single line of text string. * If you need to input multiple lines of text, you can use the _Text_ widget. * If you need to display one or more lines of text and do not allow the user to modify it, you can use the _Label_ widget. ### Syntax The syntax format is as follows: w = Entry( master, option, ... ) * master: The parent container of the button. * options: Optional parameters, i.e., the settable properties of the button. These options can be set in the form key = value and separated by commas. | No. | Options & Description | | --- | --- | | 1 | **bg** Background color of the input box | | 2 | **bd** Size of the border, default is 2 pixels | | 3 | **cursor** Shape of the cursor, such as arrow, circle, cross, plus, etc. | | 4 | **font** Font of the text | | 5 | **exportselection** By default, if you select text in the input box, it will be copied to the clipboard.

This only works when the text box has focus. | | 4 | **index ( index )** Returns the specified index value. | | 5 | **insert ( index, s )** Inserts a value into the text box. index: insertion position, s: value to insert. | | 6 | **select_adjust ( index )** Selects the value at the specified index and before the cursor position. | | 7 | **select_clear()** Clears the selection in the specified control. | | 8 | **select_from ( index )** Sets the cursor position using the index value. | | 9 | **select_present()** Returns true if there is a selection, otherwise returns false. | | 10 | **select_range ( start, end )** Selects the value at the specified index position. start (inclusive) is the start position, end (exclusive) is the end position. start must be less than end. | | 11 | **select_to ( index )** Selects the value between the specified index and the cursor. | | 12 | **xview ( index )** This method is useful when the text box is linked to a horizontal scrollbar. | | 13 | **xview_scroll ( number, what )** Used to scroll the text box horizontally. The what parameter can be UNITS, scrolling by character width, or PAGES, scrolling by text box component blocks. The number parameter: a positive number scrolls from left to right, a negative number scrolls from right to left. | ### Example In this example, clicking the button will display a message: ## Example #!/usr/bin/python# -*- coding: UTF-8 -*-from Tkinter import * top = Tk()L1 = Label(top, text="website name")L1.pack(side = LEFT)E1 = Entry(top, bd =5)E1.pack(side = RIGHT)top.mainloop() The test output is as follows: !(#) [ Python GUI Programming](#)
