python3.5 using Tkinter to make Notepad

Tkinter is a graphical interface library of Python to TK, which allows easy graphical interface design and interactive operation programming. The advantage of Tkinter is that it is easy to use and a good combination with Python. Tkinter is integrated by default in Python 3.x without the need for additional installation operations; The lack of a suitable visual interface design tool requires code to complete the window design and element layout.

This section uses a Python version of 3.x, and if you want to use Tkinter under Python 2.x, install it through Apt-get. It is important to note that Tkinter may be used slightly differently under different Python versions, with Python3 recommended.
