First you need to download the Convex-API-py package from the python package index PyPi.
pip install convex-api
You can now access the convex network, and get a balance from an existing account on the network by doing the following:
>>> from convex_api import API
>>> convex = API('https://convex.world')
>>> convex.get_balance(9)
99396961137042
You can create a new emtpy account, with now balance:
>>> key_pair = KeyPair.create()
>>> account = convex.create_account(key_pair)
>>> account.address
809
You can request some funds to the new account and then get the account information:
>>> convex_api.request_funds(1000000, account)
1000000
>>> convex.get_account_info(account)
{'environment': {}, 'address': 809, 'is_library': False, 'is_actor': False, 'memory_size': 42, 'balance': 1000000, 'allowance': 0, 'sequence': 0, 'type': 'user'}
You can export the accounts private key encoded as PKCS8 encrypt the key with a password:
>>> account.key_pair.export_to_text('secret')
'-----BEGIN ENCRYPTED PRIVATE KEY-----\nMIGbMFcGCSqGSIb3DQEFDTBKMCkGCSqGSIb3DQEFDDAcBAiMY42UY4PXHAICCAAw\nDAYIKoZIhvcNAgkFADAdBglghkgBZQMEASoEEJpwDMicGbGj2iSJesktIVYEQBsp\nKMTAHzvUyw8jZRr8WSrmxH7938sjma8XWI6lgd9jwTZzcGamog7p3zatw0Wp+jFK\nKruWAZmIqhBZ/2ezDv8=\n-----END ENCRYPTED PRIVATE KEY-----\n'
>>> account.address
809
To re-use your account again you need to import the encrypted private key and set the correct account address
>>> from api import Account, KeyPair
>>> key_pair = KeyPair.import_from_file('my_key.dat', 'secret')
>>> account = Account.create(key_pair, 809)
To create a new address with the same account keys in your new or imported account object, you can do:
>>> new_account = convex.create_account(key_pair)
>>> account.address
809
>>> new_account.address
934
To use account names, where an account name is resolved to a fixed address. You can create or load an account based on it's name by doing the following:
>>> account = convex.setup_account('my-account-name', key_pair)
>>> account.address
934
>>> convex.resolve_account_name('my-account-name')
934
>>> same_account = convex.setup_account('my-account-name', key_pair)
>>> same_account.address
934
To submit a transaction, use ConvexAPI.send(). This will cost a small about of juice, and reduce your balance
>>> convex.request_funds(1000000, account)
1000000
>>> convex.send('(map inc [1 2 3 4])', account)
{'value': [2, 3, 4, 5]}
>>> convex.get_balance(account)
996360
To send a query a transaction, this is free and can be performed by any valid account address. So for example to query a balance of an account:
>>> convex.query(f'(balance {account.address})', account)
{'value': 996360}
# this is the same as above
>>> convex.query(f'(balance {account.address})', account.address)
{'value': 996360}
# get the balance using one of the standard account addresses (#1)
>>> convex.query(f'(balance {account.address})', 1)
{'value': 996360}
