我有一个程序可以使用密钥对消息进行编码和解码，但我想让它看起来更漂亮、更专业。我的代码如下：
from random import seed, shuffle
#Encoder Function
def Encoder(user_input,SEED):
user_input = user_input.lower()
letter = ["a","b","c","d","e","f","g","h","i","j","k",'l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
Letter_code = {"a":0,"b":1,"c":2,"d":3,"e":4,"f":5,"g":6,"h":7,"i":8,"j":9,"k":10,'l':11,'m':12,'n':13,'o':14,'p':15,'q':16,'r':17,'s':18,'t':19,'u':20,'v':21,'w':22,'x':23,'y':24,'z':25}
code = ["a","b","c","d","e","f","g","h","i","j","k",'l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',]
n = []
seed(SEED)
shuffle(code)
for letter in user_input:
for let in letter:
if letter != " ":
if letter == let:
first = Letter_code[let]
n.append(code[first])
else:
n.append("~")
return ''.join(n)
#Decoder Function
def Decoder(user_input,SEED):
user_input = user_input.lower
key_list = ["a","b","c","d","e","f","g","h","i","j","k",'l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
final = ["a","b","c","d","e","f","g","h","i","j","k",'l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
seed(SEED)
shuffle(key_list)
key_code = {}
z = 0
n = []
for key in key_list:
key_code[key] = z
z += 1
for let in user_input:
if let != "~":
for Ke in key_list:
if let == Ke:
a = key_code[Ke]
n.append(final[a])
else:
n.append(" ")
return ''.join(n)
我想要一个有两个输入框的 gui，一个用于消息，另一个用于密钥，我希望它有两个按钮，一个会说编码，另一个会说解码。以及 gui 中的一个位置，最终消息将被打印并可供用户复制。如果有人可以帮助我，将不胜感激
