Add accounts

Open programs_py/counter.py and replace the code there with the following:

from seahorse.prelude import *

declare_id('11111111111111111111111111111111')

class Counter(Account):
    count: u64
    user: Pubkey

This is similar to the Poll program:

• from seahorse.prelude import * imports the necessary libraries
• declare_id('11111111111111111111111111111111'): Default ID - every Solana program starts with this ID, this is not your program's unique ID yet. This is needed to make sure your program knows its own key.

Directives

While your program doesn't support the use of any kind of top-level statement, there are a few special types of statements, referred to as directives, which provide you with greater control over the compiler beyond just the code generation. Currently, the sole directive available is 'declare_id', but future versions of Seahorse will introduce more.

• Counter is the name of our account, which is derived from the in-built base class Account
• We define three data types, for which we need to define their type by using type-annotated fields with no default value.
  • count: the current count of the counter
  • user: the user that owns the counter
