I don't know why "(" was not closed

my code is here:

import os
from cerebras.cloud.sdk import Cerebras

class chattoAI:
    def __init__(self, prompt: str):
        self.prompt = prompt

    def chatToCerebras(self):
        client = Cerebras(
            api_key=os.environ.get("My API")
        )

        completion = client.chat.completions.create(
            messages=[{'role':'user', 'content':self.prompt}],
            model='zai-glm-4.7',
            max_completion_tokens=1024,
            temperature=0.2
            top_p=1,
            stream=False
        )

        return completion.choices[0].message.content
