I’d be happy to help you monitor your Solana wallet balance. Here’s an updated version of the code that should fix the error:

import solana_sdk
from solana_sdk import account_info, program_account_info, program_error
def get_balance(account_id):
"""Get the current balance of a Solana account."""









Initialize Solana client
client = solana_sdk.SolanaClient()

Get account information using its index
account_info.get_account_info(client, account_idx)

If we get here, we get an error
if not isinstance(account_info, AccountInfo):
raise Exception("An unexpected exception occurred")

We'll get a ProgramAccountInfo for our program account
program_acc_info = program_account_info.get_program_account_info(client, account_idx)

We are looking for the 'balance' field in AccountInfo
balance_field = "balance"

If found, we return its value; otherwise, we throw an exception.
if balance_field in program_acc_info:
balance_value = float(program_acc_info[balance_field].value)
print(f"Current balance is: {balance_value}")
else:
raise Exception("Error: Expected string of length 32 (got " + str(len(balance_field.split("-"))) + ")")

Use
get_balance(solana_sdkAccountId("your_solana_account_id"))

Here’s what changed:

• We initialized the Solana client with solana_sdk.SolanaClient().

• We used get_account_info to get information about a specific account. That’s what we’re interested in.

• We then checked to see if the result was an instance of AccountInfo. Otherwise, we throw an exception.

Note: Replace "your_solana_account_id" with your actual Solana account ID. The solana_sdkAccountId function returns a string that is used as the account_idx parameter for this function.

If you are still having trouble, here are some additional steps:

• Make sure you have the latest version of the solana-sdk library.

• Make sure your Solana wallet is connected and configured correctly for API usage.

• If you are running a Linux system with solana-program installed, you may need to install the required packages using pip:

pip install --upgrade solana_sdk

• Try printing more information about the error to your console or terminal by adding print(solana_sdk.get_solana_client().print_error("error_message")). This may give you a better idea of ​​what’s going on.

If none of these steps help, provide more details about your environment and configuration, including specific version numbers for solana-sdk, Solana wallet, and Python.
