[FIXED] python cesar cipher issues

Issue

I'm new to coding and have been trying my luck at making a Cesar cipher (by following a youtube video) but keep getting a syntax error. Can anyone help?

Here's the code:

result = ""
message = ""
choice = ""

while choice != 0:
    choice = input ("\ndo you want to encrypt or decrypt a message?\nEnter1 to encrypt, 2 to decrypt and 0 to exit. ")

    if choice == '1':
        message = input ("\nEnter message for encrpytion: ")
        for i in range(0, len(message)):
            result = result +chr(ord(message)[i] - 2


                                 print (result + ('\n\n' )
                                 result = ''

                             elif choice == '2':
                                 message = input ("\nEnter message to be decrypted: ")
                                 for i in range (0, len(message)):
                                     result = result + chr(ord(message[i]) + 2)

                                     print (result + '\n\n' )
                                     result = '' 

                                 elif choice is  != 0:
                                     print ("you have entered an invalid command please try again \n\n")

Solution

You had several syntax errors, this should fix it:

result = ""
message = ""
choice = ""

while choice != '0':
    choice = input("\ndo you want to encrypt or decrypt a message?\nEnter1 to encrypt, 2 to decrypt and 0 to exit. ")

    if choice == '1':
        message = input("\nEnter message for encrpytion: ")
        for i in range(0, len(message)):
            result += chr(ord(message[i]) - 2)
        print(result)
        result = ''

    elif choice == '2':
        message = input ("\nEnter message to be decrypted: ")
        for i in range (0, len(message)):
            result += chr(ord(message[i]) + 2)
        print(result)
        result = ''

    elif choice == '0':
        break
    else:
        print ("you have entered an invalid command please try again")
