Label text Dynamic modification

The label or button has no functions such as settext or set.

However, you can use the assignment method directly to modify the

Label=enter (root,text= "My name is Rocky")

label["text"]= "My name is Ben"

Verified, you can dynamically modify the text on the label. Utf-8 Code

#coding =utf-8//This is the use of UTF8 encoding method, you can join the Python head alone. #-*-coding:cp936-*-import sys reload (SYS) sys.setdefaultencoding (' Utf-8 ') Python machine learning Algorithm library: Sklearn Install Sklearn

1. Before installing Sklearn, we need to install the NUMPY,SCIPY function library first.
NumPy Download Address:
Http://sourceforge.net/projects/numpy/files/NumPy
scipy Download Address:
Http://sourceforge.net/projects/scipy/files/Scipy
Download the Python version of the corresponding native.
2. Install Sklearn Machine Learning Library
Download Address:
Https://github.com/scikit-learn/scikit-learn
After downloading the compressed package, unzip the compressed package. Use CMD to enter the Sklearn folder and execute

Python setup.py Install

Sklearn Use

Training SVM Classifier, classifying according to classifier model

Class classify:
    def __init__ (self):
        Self.model = SVM. SVC () "" ""
    data:
    X = [[0, 0], [1, 1], [1, 0]]  # training samples
    y = [0, 1, 1]  # training Target
   "" "

    def Createmodel (self,samples,target):
        self.model.fit (samples,target)

    def predictsample (self, Sample): Return
        self.model.predict (sample)

An efficient model persistence module Joblib is provided in Sklearn to save the model to the hard disk.

From sklearn.externals import joblib
#lr是一个LogisticRegression模型
joblib.dump (LR, ' Lr.model ')
lr = Joblib.load (' Lr.model ')

Tkinter Components

Tkinter provides a variety of controls, such as buttons, labels, and text boxes, used in a GUI application. These controls are often referred to as controls or parts.

There are currently 15 kinds of tkinter components. We present these parts as well as a brief introduction in the following table:

                  The control describes
    the button          button control, and the button is displayed in the program.
    Canvas          The canvas control, display a graphical element such as a line or text
    Checkbutton     A multiple-marquee control; for providing multiple selection boxes in a program
    Entry           input controls; for displaying simple text content
    Frame           framework control; Displays a rectangular area on the screen, used as a container
    label           Label control; you can display text and bitmap
    ListBox         controls ; In the ListBox window widget is used to display a list of strings
    to      the User Menubutton menu button control, because the Display menu item.
    menu            Menu control; Displays the Menus bar, Drop-down menu, and pop-up
    menu         message control; Used to display multiline text, similar to label
    Radiobutton     radio Button control , display a radio button state
    Scale           range control, display a numeric scale, Scrollbar a scroll bar control for the range of numbers in the output limit, and       use when the content exceeds the visual area, such as a list box ...
    Text            control; Used to display multiline text
    toplevel        container controls; To provide a separate dialog box, and frame to compare similar
    spinbox         input controls; similar to entry, However, you can specify the input range value
    Panedwindow     panedwindow is a window layout-managed plug-in that can contain one or more child controls.
    Labelframe      Labelframe is a simple container control. Commonly used with complex window layouts.
    Tkmessagebox        is used to display the message box for your application.

Standard Properties

Standard properties are common properties of all controls, such as size, font, color, and so on.

    Property          describes the size of the
    Dimension       control;           color control colors; font            control fonts;
    anchor          anchor points;
    Relief          control style;
    Bitmap          bitmap;
    Cursor          cursor;
