AWS error from Python: No module named lambda_function

I am creating a AWS Lambda python deployment package. I am using one external dependency requests. I installed the external dependency using the AWS documentation. Below is my Python code. import requests print('Loading function') s3 = boto3.client('s3') def lambda_handler(event, context): #print("Received event: " + json.dumps(event, indent=2)) # Get the object from the event and show its content type bucket = event['Records'][0]['s3']['bucket']['name'] key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key']).decode('utf8') try: response = s3.get_object(Bucket=bucket, Key=key) s3.download_file(bucket,key, '/tmp/data.txt') lines = [line.rstrip('\n') for line in open('/tmp/data.txt')] for line in lines: col=line.split(',') print(col[5],col[6]) print("CONTENT TYPE: " + response['ContentType']) return response['ContentType'] except Exception as e: print(e) print('Error getting object {} from bucket {}. Make sure they exist and your bucket is in the same region as this function.'.format(key, bucket)) raise e Created the Zip the content of the project-dir directory and uploaded to the lambda(Zip the directory content, not the directory). When I am execute the function I am getting the below mentioned error.

Error was due to file name of the lambda function. The console no longer asks you what handler name you want - it just sets it to "lambda_function.lambda_handler". So, you need to make sure your filename is "lambda_function.py" and the function name in there is "lambda_handler". The other alternative is explicitly setting the name of the handler after creating the function.
