Python3.5 use tkinter to create notepad, python3.5tkinter

Tkinter is a graphical interface library for tk in Python, allowing you to easily design graphical interfaces and program interactive operations. The advantage of tkinter is that it is easy to use and has a good combination with Python. Tkinter is integrated by default in Python 3.x without additional installation operations. The disadvantage is the lack of a proper visual interface design tool, which requires code to complete the window design and element layout.

The Python version used in this section is 3.x. if you want to use tkinter in python 2.x, install tkinter using apt-get. Note that tkinter usage in different Python versions may be slightly different. We recommend using Python3.
