Beem n more

ODS dot PY

A small Python3 to store your own data on the Steem Blockchain.

Only on Steem Baby, YEAH!

First of all, I am not a programmer, just a natural born Geek who loves innovative technology. The Python programming language is actually quite new to me. So a lot of trial n error, but I'm getting the hang of it. And as long as I am having fun I'll be experimenting. Thanks to fellow Steemian Holger80 for creating the BEEM Steem Python module, The Marky Mark for the Airdrop application and Felixxx for some handy tutorials on Python.

The ods dot py file is just a simple setup for storing JSON constructed data on the Steem Blockchain. And I have build a switch that you have to set to 'True' if you actually want to store some data. With this setup it would be possible to create your own Dapp on Steem. Not just like that, but in theory. (One would be advised to run a Steem node for that, depending on the kind of data to be stored and fetched.) This is not a tutorial on Python or how to set it up on your Operating System. (Just learn how to use Linux, you'll thank me one day.)

# Test ODS setting, use the Beem key wallet!
# The Steem Account publishing 
ods_account="youraccount" 
# Beem Key Wallet open thee
pw = "beemopenthee"

# Incase of API trouble:

    'header' : 'Storing data on the Steem blockchain',

}
# Now it works like this too 
config['footer'] = "Only on Steem Baby, YEAH!\n"
config['footer'] += "Created by @" + ods_account

# the config data can be converted to JSON, but in this case it is not needed. 

# Let's build some JSON data

    ods_JSON['smartData']['title'] = config['header']
    ods_JSON['smartData']['paragraph'] = config['text']
    ods_JSON['smartData']['subscript'] = config['footer']
    # And return the object
    return ods_JSON

    # Let's prepare the data to store    
    ods_JSON = build_JSON()
    
    # Only store once
    if do_store:  
        stm.custom_json('ods-subrosa1', ods_JSON ,required_auths=[ods_account])
        print(f"Stored data: {ods_JSON}")
    else:

    main()

And there it is!
