我在输入命令的正确行上有语法错误

Question

[it automatically detects it as a string`

this is the error

input_msg = input('enter message:-')
        ^
SyntaxError: invalid syntax`]

this is my code

import time
from cryptography.fernet import Fernet
from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC

password_provided = "password"  
password = password_provided.encode() 
salt = b'salt_' 
kdf = PBKDF2HMAC(
    algorithm=hashes.SHA256(),
    length=32,
    salt=salt,
    iterations=100000,
    backend=default_backend()
)

key = base64.urlsafe_b64encode(kdf.derive(password)

input_msg = input('enter message:-')

message = input_msg.encode()

time.sleep(15)

f = Fernet(key)

code = f.encrypt(message)

print(message)

i am using vs code and my python version is 3.7 i am unable to use input func and it automatically tells me that my variable is a string as the above image

Answer 1

It looks like you are missing a closing bracket on the line above:

key = base64.urlsafe_b64encode(kdf.derive(password) # need ) here

Answer 2

You're missing a paren on the line above. Should be:

key = base64.urlsafe_b64encode(kdf.derive(password))

Answer 3

On this line: key = base64.urlsafe_b64encode(kdf.derive(password) you need to add another ) at the end.
