This article describes how to use Python + tkinter to program a simple calculator code example.

If you don't talk about it, go straight to the topic. We recommend that you repeat the code and try out the code reuse, use the string method, and dynamically create components. Then, you can supplement and give full play to this framework.

Select any Python development environment, create a program file named tkinter_Calculator.pyw, and then write the following code:

1) import the standard library re and tkinter, create and set the application master program, and place a read-only text box at the top of the window to display information.

2) Compile common processing code for various buttons on the calculator.

3) create various buttons on the calculator, set the corresponding attributes and behaviors, and start the main cycle of the message.

Compiled, run Interface

Summary

Any programming language, or even a discipline, requires more hands-on exercises in the course of learning. I hope that you can tap into the code and take actions. Although it is not just about changing the world, but there will be gains.
