使用tkinter实现 凯撒密码的破解和解密

from tkinter import *
    def encrypt():
        key = int(xls_text.get())
        message = xls_text1.get()
        str_list = list(message)
        i = 0
        while i <len(message):
            if not str_list[i].isalpha():
                str_list[i] = str_list[i]
            else:
                a = "A" if str_list[i].isupper() else "a"
                str_list[i] = chr((ord(str_list[i]) - ord(a) + key) % 26 + ord(a))
            i = i + 1
        result = ''.join(str_list)
        print(result)
        xls_text2.set(result)
    
    
    def decrypt():
        key = int(xls_text.get())
        message = xls_text1.get()
        mode = 'decrypt'
        message = message.upper()
        LETTERS = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
        translated = ''
        for symbol in message:
            if symbol in LETTERS:
                num = LETTERS.find(symbol)
    
                if mode == 'encrypt':
                    num = num+key
                elif mode == 'decrypt':
                    num = num-key
    
                if num > len(LETTERS):
                    num = num - len(LETTERS)
                elif num < 0:
                    num = num + len(LETTERS)
    
                translated = translated + LETTERS[num]
    
            else:
                translated =translated + symbol
        result = translated.lower()
        print(result)
        xls_text2.set(result)
    
    
    root = Tk()
    root.geometry('800x700')
    l1 = Label(root, text="请输入偏移量")
    xls_text = StringVar()
    xls = Entry(root, textvariable=xls_text)
    l1.pack()
    xls.pack()
    l2 = Label(root, text="输入字符")
    xls_text1 = StringVar()
    xls1 = Entry(root, textvariable=xls_text1)
    l2.pack()
    xls1.pack()
    
    B = Button(root, text="加密", command=encrypt)
    B1 = Button(root, text="解密", command=decrypt)
    B.pack()
    B1.pack()
    l_result = Label(root, text="结果")
    l_result.pack()
    xls_text2 = StringVar()
    xls2 = Entry(root, textvariable=xls_text2)
    xls_text2.set('')
    xls2.pack()
    root.mainloop()

运行结果：

thinker样式真的不好搞，就这样。
