Getting Instructions from a Solana Transaction 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 you through the process of getting instruction data from a transaction using Python.
Assumptives
Before diving into the code, make sure you have:
Code example
Let’s say you have a transaction that contains instruction data:
import axis
from py_solana import SolanaClient
Load an instance of the Solana client from environment variables or a configuration fileclient = SolanaClient(os.environ.get('SOLANA_KEY'))
Create a new transaction and add instructionstx_hash = 'your_transaction_hash'
Replace with the actual transaction hashinstruction_data = {
'key1': 'value1',
'key2': 'value2'
}
new_tx = client.transaction.add_instructions(
tx_hash,
Instruction_data,
)
Loading instruction data
To get instruction data, you can use the `get_instruction'' method in a transaction:
Get instruction data from a transactioninstructions = new_tx.get_instruction('key1')
print(instruction.data)
Output: {'value1': 'value1'}
Or get all instructions for a transactioninstructions = new_tx.get_instructions()
for instructions in the manual:
print(instruction_data)
Remember that get_instruction'' returns a dictionary containing the instruction data. To access specific fields, make sure they are defined in the
`instruction_data” dictionary.
Error Handling
Remember that error handling is very important when working with Solana transactions. Don’t forget to check return values and consider possible exceptions:
try:
Get instruction datainstructions = new_tx.get_instruction('key1')
print(instruction.data)
Output: {'value1': 'value1'}except solana.exceptions.TransactionFailedError as e:
print(f"Transaction failed: {e}")
Conclusion
Retrieving instructions from a Solana transaction using Python is a simple process. After following these steps, you can get the required data and continue your program. Don’t forget to always handle errors and check return values to make sure your code is running smoothly.
As a beginner in 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 additional help, don’t hesitate to ask!
