String type operation The string is the most basic type of Redis, and the string type is binary safe. This means that a Redis string can contain any data. For example, JPG images or serialized objects $redis->set (' key ', ' TK '); $redis->set (' number ', ' 1 '); $redis->setex (' key ', 5, ' TK '); Set a key value that is valid for 5 seconds $redis->psetex (' key ', ' the ', ' the '

licenses.For Python programmers, the default GUI option is Tk (bound through tkinter)-The reason is obvious. Tkinter and idle IDE are compiled by the python founder and appear as the default choice for most Python distributions. The standard Python document discusses tkinter, but does not involve any other GUI bindings. This is intentional! At least so, if TK and tkinter are not so bad, programmers have no

On some occasions, we need to visualize data. It is difficult to rely on tkinter alone, and the effect is not necessarily ideal.At this point, combining Tkinter with Matplotlib is the best choice.Knowledge Points:The whole routine of combining tkinter with matplotlib is fixed, just care about our drawing logic and program logicImportMatplotlibmatplotlib.use ('Tkagg')ImportNumPy as NP fromMatplotlib.backends.backend_tkaggImportFigurecanvastkagg, Navigationtoolbar2tkagg fromMatplotlib.figureImport

What ' s tkinter?What is Tkinter. The tkinter module ("Tk interface") is the standard Python interface to the TK GUI Toolkit from Scriptics (former Ly developed by Sun Labs). The Tkinter module is the standard Python interface for the Tk GUI suite. Both Tk and Tkinter are available on most Unix platforms, as as is on

Regardless of the conventional approach, let's try a lightweight and practical example. It will give you an idea of the initial feeling behind the TK program. DesignThe example we use is a simple GUI tool that converts a number in a unit of foot into a metric unit number equal to it. If we describe it briefly, it should look like this: it looks like we need a short text input widget that allows us to enter a number in a foot unit and a ' Calculate '
