### Get Wallet Info

Let's get details of our wallet:

You can similarly retrieve your wallet's information with the `getwalletinfo` RP:

||||
```py
|
||||
wallet_info = rpc_client.getwalletinfo()

Other informational commands such as `getblockchaininfo`, `getnetworkinfo`, `getpeerinfo`, and `getblockchaininfo` will work similarly.

Try out other commands like `getblockchaininfo`, `getnetworkinfo`, `getpeerinfo`, `getblockchaininfo`, etc.

Other commands can give you specific information on select elements within your wallet.

### Retrieving an Array
|
||||
|
||||
```
|
||||
|
||||
## Exploring an Address
|
||||
|
||||
How about getting a list of all the transactions of your address? Type the following and see the transaction history of your address:
|
||||
The `listtransactions` RPC allows you to look at the most recent 10 transactions on your system (or some arbitrary set of transactions using the `count` and `skip` arguments). It shows how an RPC command can return an easy-to-manipulate array:
|
||||
|
||||
```py
|
||||
track_address = "<your address>"
|
||||
tx_list = rpc_client.listtransactions()
|
||||
address_tx_list = []
|
||||
for tx in tx_list:
|
||||
if tx['address'] == track_address:
|
||||
address_tx_list.append(tx)
|
||||
pprint(address_tx_list)
|
||||
pprint(tx_list)
|
||||
```
|
||||
|
||||
## Exploring a UTXO
|
||||
### Exploring a UTXO
|
||||
|
||||
To get details of a UTXO, we first need to get its `hex` id, which we can then decode using `decoderawtransaction`.
|
||||
You can similarly use `listunspent` to get an array of UTXOs on your system:
|
||||
|
||||
```py
|
||||
print("Exploring UTXOs")
|
||||
@ -226,12 +216,21 @@ print("Utxos: ")

||||
print("-----")
|
||||
pprint(utxos)
|
||||
print("------------------------------------------\n")
|
||||
```
|
||||
|
||||
In order to manipulate an array like the one returned from `listtransactions` or `listunpsent`, you just grab the appropriate item from the appropriate element of the array:
|
||||
```
|
||||
## Select a UTXO - first one selected here
|
||||
utxo_txid = utxos[0]['txid']
|
||||
## Get UTXO Hex
|
||||
```
|
||||
|
||||
For `listunspent`, you get a `txid`. You can retrieve information about it with `gettransaction`, then decode that with `decoderawtransaction`:
|
||||
|
||||
```
|
||||
utxo_hex = rpc_client.gettransaction(utxo_txid)['hex']
|
||||
## Get tx Details

Now that we have established comfort between our python and bitcoind interface, lets create and broadcast a transaction. For the purposes of this course, we will send test bitcoins to an address generated by us in our testnet wallet. Here's how we will do it:
