Here is an article on how to extract transaction instruction data in Python:

Extracting Transaction Instruction Data in Solana with Python

As a developer who uses Solana and Solders for your programming tasks, you are probably familiar with the solana-program' library. In this article, we will walk through the process of extracting transaction instruction data using Python.

• Thesolana-programlibrary installed (pip install solana-program)

• Thepy-solanalibrary for interacting with the Solana network (pip install py-solana)

import if
from py_solana import SolanaClient









Load the Solana client instance from your environment variables or configuration file
client = SolanaClient(os.environ.get('SOLANA_KEY'))

Create a new transaction and add instructions
tx_hash = 'your_transaction_hash' 
Replace with the actual hash of your transaction
instruction_data = {
'key1': 'value1',
'key2': 'value2'
}
new_tx = client.transaction.add_instructions(
tx_hash,
instruction_data,
)

To get instruction data, you can use the transaction's get_instructionmethod:

Get instruction data from transaction
instruction = new_tx.get_instruction('key1')
print(instruction.data) 
Output: {'value1': 'value1'}

Or, to get all instructions in transaction
instructions = new_tx.get_instructions()
for instructions in instructions:
print(instruction.data)

Note that get_instructionreturns a dictionary containing instruction data. If you want to access specific fields, make sure they are defined in yourinstruction_data’ dictionary.

Error Handling

Keep in mind that error handling is crucial when working with Solana transactions. Be sure to check the return values ​​​​and handle potential exceptions:

try:

Get the instruction data
instruction = new_tx.get_instruction('key1')
print(instruction.data) 
Output: {'value1': 'value1'}
except solana.exceptions.TransactionFailedError as e:
print(f"Transaction failed: {e}")

Conclusion

Recovering instruction data from a Solana transaction using Python is a straightforward process. By following these steps, you can extract the desired data and continue with your program. Remember to always handle errors and check return values ​​​​to make sure your code runs smoothly.

As a beginner to the world of Solana programming, this should give you a solid understanding of how to work with instruction data. If you have any questions or need further help, don’t hesitate to ask!
