壓縮句子轉化成ASCII碼，然後解壓回

Question

當我想這句話壓縮到​​ASCII對等，我不斷收到此錯誤代碼TypeError: ord() expected a character, but string of length 5 found

如何解決下面的代碼

def menu(): 
    print("Compress a file       Press 1") 
    print("Decompress a file       Press 2") 
    print("Quit          Press 3") 
    user_choice = input("") 
    if user_choice=="1": 
     compressing() 
    elif user_choice=="2": 
     decompressing() 
    elif user_choice=="3": 
     import sys 
     sys.exit() 
    else: 
     print("Input invalid.Please enter a number for path selection") , "\n" , menu() 

def compressing(): 
    compressed_sentence=[] 
    sentence=input("Enter a sentence: ") 
    sentence=sentence.split() 
    for i in range(len(sentence)): 
     character=(sentence[i]) 
     ascii_character=ord(character) 
     compressed_sentence.append(ascii_character) 
    with open('compressed_file.txt','w') as myFile: 
     myFile.write(str(compressed_sentence)) 
    menu() 

def decompressing(): 
    with open('compressed_file.txt','r') as myFile: 
     sentence=myFile.read() 
    for i in sentence: 
     if i in "[],'": 
      sentence=sentence.replace(i," ") 
    new_sentence=sentence.split() 
    decompressed_sentence=str("") 
    for i in range(len(new_sentence)): 
     character=int(new_sentence[i]) 
     decompressed_sentence=(decompressed_sentence+(chr(character))) 
    final_decompressed_sentence=decompressed_sentence.split() 
    print(final_decompressed_sentence) 
    with open('decompressed_file.txt','w') as myFile: 
     myFile.write(final_decompressed_sentence) 
    menu() 

menu() 

爲了能夠正確地壓縮和解壓縮它。

它的好，我得到它的工作：

def menu(): 
    print("Create a file        Press 1") 
    print("Compress a file       Press 2") 
    print("Decompress a file       Press 3") 
    print("Quit          Press 4") 
    user_choice = input("") 
    if user_choice=="1": 
     create_a_file() 
    elif user_choice=="2": 
     compressing() 
    elif user_choice=="3": 
     decompressing() 
    elif user_choice=="4": 
     import sys 
     sys.exit() 
    else: 
     print("Input invalid.Please enter a number for path selection") , "\n" , menu() 

def create_a_file(): 
    sentence=input("Enter a sentence: ") 
    sentence=sentence.split() 
    with open('file.txt','w') as myFile: 
     myFile.write(str(sentence)) 
    menu() 

def compressing(): 
    compressed_sentence=[] 
    with open('file.txt','r') as myFile: 
     sentence=myFile.read() 
    for i in sentence: 
     if i in "[],'": 
      sentence=sentence.replace(i," ") 
    for i in range(len(sentence)): 
     character=(sentence[i]) 
     ascii_character=ord(character) 
     compressed_sentence.append(ascii_character) 
    with open('compressed_file.txt','w') as myFile: 
     myFile.write(str(compressed_sentence)) 
    menu() 

def decompressing(): 
    with open('compressed_file.txt','r') as myFile: 
     sentence=myFile.read() 
    for i in sentence: 
     if i in "[],'": 
      sentence=sentence.replace(i," ") 
    new_sentence=sentence.split() 
    decompressed_sentence=str("") 
    for i in range(len(new_sentence)): 
     character=int(new_sentence[i]) 
     decompressed_sentence=(decompressed_sentence+(chr(character))) 
    final_decompressed_sentence=decompressed_sentence.split() 
    print(final_decompressed_sentence) 
    menu() 

menu()
