Project directory structure

Suppose your project directory is like this:

├── event.json
├── lib
│   ├── rx
│   │   ├── abstractobserver.py
│   │   ├── ... (package content of rx)
...
│   │       └── testscheduler.py
│   └── Rx-1.2.3.dist-info
│       ├── DESCRIPTION.rst
│       ├── METADATA
│       ├── metadata.json
│       ├── pbr.json
│       ├── RECORD
│       ├── top_level.txt
│       ├── WHEEL
│       └── zip-safe
└── test.py

In the handler’s code is in test.py and the function name of the handler is handler. The source depends on 3rd party library rx and it is install in the directory lib. The test event of json format is in event.json file.

Content of test.py:

from rx import Observable


def handler(event, context):
    xs = Observable.from_([1, 2, 3, 4, 5, 6])
    ys = xs.to_blocking()
    zs = (x*x for x in ys if x > 3)
    for x in zs:
        print x

Content of event.json:

{
  "key": "value"
}

Run the lambda function

Within the project root directory, you can run the lambda function with the following command

python-lambda-local -l lib/ -f handler -t 5 test.py event.json

The output will be like:

[INFO 2015-10-16 18:21:14,774] Event: {'key': 'value'}
