how to count the number of methods other than OPTION on AWS API Gateway with python

Question

I need to count the number of methods on AWS API Gateway. I'm very new to python scripting. It doesn't care about any path, and it's just that the OPTIONS method doesn't count. GET, POST, PUT, etc. sections (exclude OPTION)

Here I attach the code that I'm currently trying to implement.

import boto3

Create a client for the API Gateway service

client = boto3.client('apigateway')

Get the ID of the API Gateway

api_id = 'my_api_id'

Get the list of resources in the API Gateway

resources = client.get_resources(restApiId=api_id)

Initialize a variable to store the number of methods

method_count = 0

# Get the list of methods for each resource
for resource in resources['items']:
    resource_methods = client.get_methods(restApiId=api_id, resourceId=resource['id'])
    for method in resource_methods['items']:
        if method['httpMethod'] != 'OPTIONS':
            method_count += 1

# Print the number of methods
print(method_count)

I got this error and am still confused about doing the calculations. Please help. Your response is precious.
