在YAML中需要将一个lambda函数(python)加入到CloudFormation模板中，如何实现？

Resources:
  MyLambdaFunction:
    Type: AWS::Lambda::Function
    Properties:
      FunctionName: MyLambdaFunction
      Runtime: python3.8
      Handler: index.lambda_handler
      Code:
        ZipFile: |
          import json
          def lambda_handler(event, context):
              # Lambda函数的代码逻辑
              return {
                  'statusCode': 200,
                  'body': json.dumps('Hello from Lambda!')
              }
      Role: !GetAtt MyLambdaExecutionRole.Arn

Outputs:
  MyLambdaFunctionArn:
    Value: !GetAtt MyLambdaFunction.Arn
    Description: ARN of the Lambda function
