Using boto to invoke lambda functions how do I do so asynchronously? : <p>SO I'm using boto to invoke my lambda functions and test my backend. I want to invoke them asynchronously. I have noted that "invoke_async" is deprecated  and should not be used. Instead you should use "invoke" with an InvocationType of "Event" to do the function asynchronously.  </p>

<p>I can't seem to figure out how to get the responses from the functions when they return though. I have tried the following: </p>

<pre><code>payload3=b"""{
"latitude": 39.5732160891,
"longitude": -119.672918997,
"radius": 100
}"""

client = boto3.client('lambda')
for x in range (0, 5):
    response = client.invoke(
        FunctionName="loadSpotsAroundPoint",
        InvocationType='Event',
        Payload=payload3
    )
    time.sleep(15)
    print(json.loads(response['Payload'].read()))
    print("\n")
</code></pre>

<p>Even though I tell the code to sleep for 15 seconds, the response variable is still empty when I try and print it. If I change the invokation InvokationType to "RequestResponse" it all works fine and response variable prints, but this is synchronous. Am I missing something easy? How do i execute some code, for example print out the result, when the async invokation returns??</p>

<p>Thanks.</p>
