Absrtact: When programming with the Python process GUI, you often need to use the ListBox component, and how to control the display of the ListBox component, you need to use the ScrollBar component. This article focuses on the binding of actions between two GUI components--------the action of one component will start the corresponding action of another component.

we continue to calculate the subsequent elements in the process of the loop? This eliminates the need to create a complete list, which saves a lot of space, and in Python, this side loop computes the mechanism called the generator: generatorThe generator is a special program that can be used as an iterative behavior for controlling loops, where the generator in Python is one of the iterators, using the yie

Python yield keyword, yield is a generator in PythonUnderstanding the builder needs to understand what the build is, the purpose of the slice is to cut out a portion of the existing list, and the purpose of the build is to build a list from scratchA built-in caseWhat can I do if I build a list of 10 elements?You can use Python's built-in function range to produce some numbers, and then use loops to populate

Tkinter is the standard GUI library in the python release version. That is to say, tkinter can be used after python is installed by default.

If you want to use Python to develop a graphical interface, there are many tools to choose from, each with the pros and cons, previously used Wxpython+boa-constructor, has not been clear. New understanding of the next PyQt4, seems to use this person also more, so decided to start learning this. Version:pyqt-py2.7-x86-gpl-4.9.1-1.exe PyQt4 takes a QT designer and uses it to create an interface, layout controls such as Form,button,text, and so on, using

implicitly means that the function is returning control of the execution code to the place where the function is invoked. The implied meaning of "yield" is that the transfer of control is temporary and voluntary, and our function will reclaim control in the future. In Python, a "function" with this ability is called a builder, and it is very useful. The generator (and yield statement) was first introduced
