, you can see how simple it is to create a fast GUI based on an application, but this program has only a few improvements, such as the multi-threaded text area, or copy an easy sticker to the clipboard to automatically save it, and so on. It is an appropriate way to save your trace to the list. I will leave this as an exercise. If you want to find more text blocks about what you can do with python in TK, th
1.Python IntroductionPython is a high-level language, equivalent to Java C #. You can write a variety of applications, each of which has its own appropriate application scenario. While PythonHas the advantage of being more user-friendly, easy-to-use grammar rules, and a code base that many predecessors have written for a variety of specific scenarios, so that pro
How to test without patience
Often, the software we write interacts directly with what we call a "dirty" service. In layman's terms, services are critical to our application, and the interaction between them is designed for us, but this leads to undesirable side effects--those that we don't want when we test ourselves.
For example, maybe we're writing a social software program and want to test "features posted to Facebook," but we don't want to be po
