Python3 Previous version with Tkinter, followed by TkinterThe simplest code to use Tkinter is to first create a window of TK () and then add the various widgetsFrom Tkinter Import *window = Tk () label = label (window, Text = "Welcome to Python") button = button (window, Text = "click M E ") Label.pack () Button.pack () Window.mainloop ()Tkinter programming is event-driven, and when a button is clicked, the

This article lists and describes Python's standard library and Third-party libraries as follows for reference to friends who need it: Tkinter ———— Python's default graphical interface.Tkinter is a module with the TK interface, and the Tkinter library provides an interface to the TK API, which belongs to the TCL/TK GUI tool group.

document vector space, a fixed class collection C={c1,c2,..., CJ}, and a category called a label. Obviously, the document vector space is a high dimensional space. We have a bunch of tagged documents set For this one-sentence document, we classify it in the US, which is labeled "the". We expect to use some kind of training algorithm to train a function γ to map documents to a certain category: Γ:x→c This type of learning is called supervised learning, because there is a supervisor (we give a

) -PID control algorithm is one of them.Iii. PID control crawling speed The PID controller controls the crawling speed simply by increasing the speed, latency, and speed, reduce the delay time-have you seen the similarity between it and the fire condition described at the beginning of this article? Similar to the fire, I imagine the PID's solution for controlling crawler speed is: 1) initialization: Set the initial delay timeT0 and proportional coefficientKP (Classic-0.05) 2) target setting: Set

In 10.5, I downloaded Git-OSX-installer from code.google.com to install it. However, from the git-1.6.4.1, the author upgraded the Tcl/tk version of git GUI dependency to 8.5 (osx10.5 default installation of Tcl/TK is 8.4 ), therefore, an error is reported when running git GUI in osx10.5. The solution is to download the Tcl/tk Version 8.5 and install it on your

Python supports Third-party libraries for a variety of graphical interfaces, including: WxWidgets Qt Gtk The Tkinter:tkinter module (TK interface) is the interface of the standard TK GUI Toolkit for Python. Tk and Tkinter can be used on most Unix platforms and can also be applied to Windows and Macintosh systems. Subsequent versions of Tk8.0 can be implemented i

Rapid development of desktop applications using the Monkeybars JRuby Swing Library With Ruby, in addition to building WEB and console applications, you can write complex GUI desktop applications that can run on a variety of platforms without modification. Thanks to Jruby,ruby's traditional C-implementation robust alternatives, the Ruby GUI Toolkit can use UI tools for the Java platform. This article describes a library monkeybars that uses JRuby and Swing to build an application, and explains a

, therefore both the prior probability and the class conditional probability are calculated differently. When calculating the posteriori probability, for a document D, the polynomial model, only the words that appear in D will participate in the posteriori probability calculation, the Bernoulli model does not appear in D , but the words appearing in the global Word table will also participate in the calculation. However, they are involved as " opposing parties " . In this paper, the feature extr
