button按鈕的生成：import?Tkinter?as?tk

window=tk.Tk()

def?buttonClick():

print?"Beep!"

button=tk.Button(window,text="Click?me!",command=buttonClick)

button.pack()

window.mainloop()

同理將方法改為改變按鈕上的文字import?Tkinter?as?tk

window=tk.Tk()

def?buttonClick():

#????print?"Beep!"

button.config(text="Clicked!")

button=tk.Button(window,text="Click?me!",command=buttonClick)

button.pack()

window.mainloop()

點擊按鈕的計數import?Tkinter?as?tk

window=tk.Tk()

count=0

def?buttonCount():

global?count

count+=1

button.config(text=str(count))

button=tk.Button(window,text="count",command=buttonCount)

button.pack()

window.mainloop()

創建文本框，里面有一個按鈕和文本框，通過獲取文本框的內容，每點擊一次按鈕，都復制文本框中的內容并一起顯示在文本框中。import?Tkinter?as?tk

window=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()

其中，entry.insert中參數第一個為插入的位置。

將文本框中的內容反面顯示于文本框中import?Tkinter?as?tk

window=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()

添加密碼框，用于輸入密碼的文本框常常在輸入密碼時不會顯示密碼，而是在每個字符的位置顯示星號(*),使用方式：在添加文本框時，添加一個額外的具名自變量，這樣文本框就變成了一個密碼框

在GUI中會有一個輸入密碼的框和一個提交密碼的按鈕。如果密碼正確，底部會出現一個寫有Correct的標簽，負責它會寫Incorrect。import?Tkinter?as?tk

window=tk.Tk()

def?checkPassword():

password="Apple"

enterPass=passwordEntry.get()

if?enterPass?==?password:

confirmLabel.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()

構造句子生成器：列表與隨機函數的配合使用import?Tkinter?as?tk

import?random

window=tk.Tk()

def?randomNoun():

nouns=["cats","hippos","cakes"]

noun=random.choice(nouns)

return?noun

def?randomVerb():

verbs=["eats","likes","hates","has"]

verb=random.choice(verbs)

return?verb

def??buttonClick():

name=nameEntry.get()

verb=randomVerb()

noun=randomNoun()

sentence=name+"?"+verb+"?"+noun

result.delete(0,tk.END)

result.insert(0,sentence)

nameLabel=tk.Label(window,text="Name:")

nameEntry=tk.Entry(window)

button=tk.Button(window,text="Generate",command=buttonClick)

result=tk.Entry(window)

nameLabel.pack()

nameEntry.pack()

button.pack()

result.pack()

window.mainloop()

猜數字游戲：生成一個1-10之間的隨機數，看是否成功猜測，并計算游戲的勝利次數(標簽顯示)import?random

except:
