如何解决第二个脚本虚线下方中的EOF问题？

如何解决如何解决第二个脚本虚线下方中的EOF问题？

此程序实质上是分别对消息和代码进行编码和解码。到目前为止，我只做过解码部分。但是，即使我确保结束括号，检查我的语法并不断对其进行篡改，我仍然收到EOF错误。不幸的是没有运气。有人知道为什么这个错误不断弹出吗？我将不胜感激。我也复制了我正在使用的两个文件。

from LetterCodeLogic import LCL

def main():
    print("Welcome to the LetterCode program")

choice = getChoice()
while choice !=0:
    if choice == 1:
        #Encode logic...
        print()
    elif choice == 2:
        #Decode logic...
        msg = input("Enter your numbers to decode (separate with commas): ")
        #send msg to Decode function in LCL class (LetterCodeLogic.py file)
        result = LCL.Decode(msg)
        print("Your decoded message is: \n" + result)
    else:
        print("Unknown process...")
    print()
    choice = getChoice()
print("Thanks for using the Letter Code program")

def getChoice():
    c = int(input("Choice? (1=Encode,2=Decode,0=Quit): "))
    return c

if __name__ == "__main__":
    main()

class LCL:
"""Encode/Decode Functions"""

@staticmethod
def Decode(msg):
    #separate numbers from msg string (e.g.,"1,2,3")
    nums = msg.split(",")   #produces list of separate items
    result = ""
    for x in nums:
        try:
            n = int(x.strip())  #remove leading/trailing spaces...
            if n == 0:
                c = " "
            elif n < 0 or n > 26:
                c = "?"
            else:
                #ASCII scheme has A=65,B=66,etc.
                c = chr(n+64)
        except ValueError:
            c = "?"
            
        result += c     #same as: result = result + c
        
    return result


@staticmethod
def Encode(msg):

解决方法

“ @ staticmethod”和“ def Encode（）”函数为空，这是行解析错误的结尾。当我编码并运行它时，它没有问题。所以我暂时将其删除。
