将 object 放入 S3 存储桶时出错

Question

I am trying to get temperature value from DynamoDB table and calculating the average of that values and sending average value to S3 bucket. I calculated the Average value but when putting that value to s3 bucket I got the error:

Response:

{
  "errorMessage": "Syntax error in module 'lambda_function': positional argument follows keyword argument (lambda_function.py, line 45)",
  "errorType": "Runtime.UserCodeSyntaxError",
  "stackTrace": [
    "  File \"/var/task/lambda_function.py\" Line 45\n        s3.put_object(Bucket='mys3pooja', Key='time', Body=val)\n"
  ]
}

Answer 1

Error you're shown is syntax related.

If you have function or method with signature like def foo(bar, foo="something") , it has positional argument bar and keyword argument foo . Python's convention is to always put positional arguments before keyword ones when you call this function, so result = foo(1, foo="text") is correct, but result = foo(foo="text", 1) is incorrect
