Passing local data
==================

If you have a function that needs access to some data not present in your Python files themselves you have a few options for bundling that data with your Modal App.

Passing function arguments 

The simplest and most straight-forward way is to read the data from your local script and pass the data to the outermost Modal Function call:

    import json
    
    
    @app.function()
    def foo(a):
        print(sum(a["numbers"]))
    
    
    @app.local_entrypoint()
    def main():
        data_structure = json.load(open("blob.json"))
        foo.remote(data_structure)

Any data of reasonable size that is serializable through [cloudpickle](https://github.com/cloudpipe/cloudpickle)
 is passable as an argument to Modal Functions.

Refer to the section on [global variables](https://modal.com/docs/guide/global-variables)
 for how to work with objects in global scope that can only be initialized locally.

Including local files 

For including local files for your Modal Functions to access, see [Defining Images](https://modal.com/docs/guide/images)
