Button's Build:

Import Tkinter as TKWINDOW=TK. Tk () def buttonclick (): print "beep!" Button=tk. Button (window,text= "Click me!", Command=buttonclick) Button.pack () Window.mainloop ()

The same way change the method to the text on the button

Import Tkinter as TKWINDOW=TK.    Tk () def buttonclick (): # print "beep!" Button.config (text= "clicked!") Button=tk. Button (window,text= "Click me!", Command=buttonclick) Button.pack () Window.mainloop ()

Click the Count of buttons

Import Tkinter as TKWINDOW=TK. Tk () Count=0def buttoncount (): Global Count Count+=1 button.config (TEXT=STR (count)) button=tk. Button (window,text= "Count", Command=buttoncount) Button.pack () Window.mainloop ()

Create a text box with a button and text box that copies the contents of the text box and displays it together in a text box by getting the contents of the text box, each time you click the button.

Import Tkinter as TKWINDOW=TK. Tk () def changestr (): Stringcopy=entry.get () Entry.insert (0,stringcopy) entry=tk. Entry (window) button=tk. Button (window,text= "Strchange", Command=changestr) Entry.pack () Button.pack () Window.mainloop ()

Where the first parameter in the Entry.insert is the inserted position.

Display the contents of the text box in the text box

Import Tkinter as TKWINDOW=TK. Tk () def changestr (): Stringcopy=entry.get () stringcopy=stringcopy[::-1] Entry.delete (0,TK. END) Entry.insert (0,stringcopy) entry=tk. Entry (window) button=tk. Button (window,text= "Strchange", Command=changestr) Entry.pack () Button.pack () Window.mainloop ()

The Add Password box, the text box used to enter a password, often does not display a password when entering a password, but instead displays an asterisk (*) at the location of each character, using: When adding a text box, add an additional named argument so that the text box becomes a password box

In the GUI there will be a box to enter the password and a button to submit the password. If the password is correct, a correct tag will appear at the bottom, which will write incorrect.

Import Tkinter as TKWINDOW=TK. Tk () def checkpassword (): password= "Apple" Enterpass=passwordentry.get () if Enterpass = = Password:confirml Abel.config (text= "Correct") Else:confirmLabel.config (text= "incorrect") passwordlabel=tk. Label (window,text= "Password") passwordentry=tk. Entry (window,show= "*") button=tk. Button (window,text= "Enter", Command=checkpassword) confirmlabel=tk. Label (window) passwordlabel.pack () Passwordentry.pack () Button.pack () Confirmlabel.pack () Window.mainloop ()

Construct a sentence generator: list and random functions in conjunction with

Entry (window) namelabel.pack () Nameentry.pack () Button.pack () Result.pack () Window.mainloop () 

Guess number game: Generate a random number between 1-10 to see if it's a successful guess and count the number of wins (label display)

Import randomimport tkinter as tkwindow=tk. Tk () Maxno=10score=0rounds=0def buttonclick ():    global score     global rounds    try:        guess=int ( Guessbox.get ())         if 0<guess<=maxNo:             result=random.randrange (1,maxNo+1)              if guess==result:                 score=score+1             rounds+=1        else:             result= "Entry not valid"      except:        result= "Entry not valid"     resultlabel.config (text=result)      scorelabel.config (TEXT=STR (Score) + "/" +str (rounds))     guessbox.delete (0,TK.

Label (window) button=tk. button (window,text= "Guess", Command=buttonclick) Guesslabel.pack () Guessbox.pack () Resultlabel.pack () Scorelabel.pack () Button.pack () Window.mainloop () "IMPORT&NBSP;TKINTER&NBSP;AS&NBSP;TKWINDOW=TK". Tk () slider=tk. Scale (WINDOW,FROM_=0,TO=100) Slider.pack () Tk.mainloop ()

Creation and use of scroll bars

Import Tkinter as TKWINDOW=TK. Tk () slider=tk. Scale (WINDOW,FROM_=0,TO=100) Slider.pack () Tk.mainloop ()

Creating a canvas

Import Tkinter as TKWINDOW=TK. Tk () colour= "#FF0000" CANVAS=TK. Canvas (Window,height=300,width=300,bg=colour) Canvas.pack () Window.mainloop ()

Color Picker: Working with the canvas with the scroll bar

Note: Through the selection of three scroll bars to determine the three primary colors red, green, blue three-color occupy, thus forming a favorite color. In the actual painting, all the colors are composed of red, yellow, and blue blends.

Import Tkinter as TKWINDOW=TK. Tk () def sliderupdate (source): Red=redslider.get () Green=greenslider.get () blue=blueslider.get () colour= "#% 02x%02x%02x "% (red,green,blue) canvas.config (bg=colour) redslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) greenslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) blueslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) canvas=tk. Canvas (window,width=200,height=200) Redslider.grid (row=1,column=1) Greenslider.grid (row=1,column=2) Blueslider.grid (row=1,column=3) Canvas.grid (row=2,column=1,columnspan=3) Tk.mainloop ()

Improved: Add a text box to display the selection of three primary colors (16 binary)

Import Tkinter as TKWINDOW=TK. Tk () def sliderupdate (source): Red=redslider.get () Green=greenslider.get () blue=blueslider.get () colour= "#% 02x%02x%02x "% (red,green,blue) canvas.config (bg=colour) hextext.delete (0,TK. END) Hextext.insert (0,colour) redslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) greenslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) blueslider=tk. Scale (Window,from_=0,to=255,command=sliderupdate) canvas=tk. Canvas (window,width=200,height=200) hextext=tk. Entry (window) Redslider.grid (row=1,column=1) Greenslider.grid (row=1,column=2) Blueslider.grid (row=1,column=3) Canvas.grid (row=2,column=1,columnspan=3) Hextext.grid (row=3,column=1,columnspan=3) Tk.mainloop ()

A game with click Speed: Record the number of clicks until the target is reached and the output takes time
