如何在python中添加来自不同列表的列表项？

Question

我正在尝试用python创建一个一次性pad-esque密码。为此，我将所有纯文本和键转换为ASCII码，然后将它们相加，然后将它们转换回常规字符。然而，当我尝试将这两个数字相加时，我却陷入了困境。这是我的密码：

#Creating initial variables
plainText = str(input('Input your plain text \n --> ')).upper()
key = str(input('Input your key. Make sure it is as long as your plain text.\n --> ')).upper()

#>Only allowing key if it is the same size as the plain text
if len(key) != len(plainText):
    print('Invalid key. Check key length.')
    key = str(input('Input your key. Make sure it is as long as your plain text. \n --> ')).upper()
else:
    plainAscii=[ord(i) for i in plainText]
    keyAscii=[ord(k) for k in key]

print (plainAscii)
print (keyAscii)

#Adding the values together and putting them into a new list
cipherText=[]
for i in range(0, len(key)):
    x = 1
    while x <= len(key):
        item = plainAscii[x] + keyAscii[x]
        cipherText.append(item)
        x = x + 1
print(cipherText)

我正在打印测试清单。但是，它仅在打印前两个列表后返回：

 Traceback (most recent call last):
  File "/Users/chuckii/Desktop/onetimepad.py", line 21, in <module>
    item = plainAscii[x] + keyAscii[x]
IndexError: list index out of range

请忽略我的少年用户名，我10岁的时候做的。提前谢谢。你知道吗

更高效地编辑：

cipherText=[]

for i in range(len(key)):
    for x in range(len(key)):
        item = plainAscii[x] + keyAscii[x]
        cipherText.append(item)

print(cipherText)

我们应该解决它！你知道吗
