用spyder编程python程序时，出现错误怎么修改

import string
import os
def vigenereEncrypt(msg, key): 
    size = len(key)
    result = []
    cnt= 0
    for i in msg:
        if i.upper() in string . ascii_uppercase:
            #offset相当于是ki
            offset = string.ascii_uppercase.find(key[cnt%size])
            t = string.ascil_uppercase[(string.ascii_uppercase.find(i.upper())+offset)%26] #这里相当于是c1 = (mi+ki)(mod 26) ,t = C
            if i. isupper():
                result . append(t)
            else: 
                result . append(t. lowerO)
            cnt+=1
        else:
            result.append(i)
    return"".join(result)
def main():
    msg="Comwon sense is not So comwon"
    cipher = vigenereEncrypt(msg, "3420") #key = "PIZZA:
    print(cipher)
if  __name__== "__moin__":
    main()

上述代码出现以下错误，请问如何修改
NameError: name 'result' is not defined

修改了代码里的拼写错误，可以正常运行

import string

def vigenereEncrypt(msg, key):
    size = len(key)
    result = []
    cnt = 0
    for i in msg:
        if i.upper() in string.ascii_uppercase:
            # offset相当于是ki
            offset = string.ascii_uppercase.find(key[cnt % size])
            t = string.ascii_uppercase[
                (string.ascii_uppercase.find(i.upper()) + offset) % 26]  # 这里相当于是c1 = (mi+ki)(mod 26) ,t = C
            if i.isupper():
                result.append(t)
            else:
                result.append(t.lower())
            cnt += 1
        else:
            result.append(i)
    return "".join(result)


def main():
    msg = "Common sense is not So common"
    cipher = vigenereEncrypt(msg, "3420")  # key = "PIZZA:
    print(cipher)


if __name__ == "__main__":
    main()
