A Python 2/3 SDK for the Bytom https://github.com/Bytom/bytom/wiki

python-bytom return an object that parsed from `json` for each method, set `return_json=True` get the original API response, set `return_dict=True` get dict object.

### Installation
```
pip install python-bytom
```

### Requires
  * requests
  * simplejson
  * six

### Getting started
#### Create Bytom Client
Create bytom client with local node, default url is http://localhost:9888:
```python
from bytom.client import BytomAPI

api = BytomAPI()
```

or

 Create bytom client with remote node:
```python
from bytom.client import BytomAPI

url = 'http://YOUR_HOST:9888'
access_token = 'YOUR_ACCESS_TOKEN'
api = BytomAPI(url, access_token)
```

#### API response
use python object as return:
```python
ret = api.wallet_info()
print ret.best_block_height # 76251
print ret.wallet_height     # 76251
```
or

use Dict object as return:
```python
ret = api.get_block_count(return_dict=True)
print ret                   # {u'block_count': 76409}
print ret["block_count"]    # 76409
```
or

use original API response (JSON) as return:
```python
ret = api.get_block_count(return_json=True)
print ret                   # '{"block_count": 80267}'
```

### Sign transaction offline
now we can use python-bytom to implement sign trasaction offline.

Parameters:
* private keys list
* transaction object or dict
* raw transaction object or dict

#### usage examples:
method:
```python
from bytom.signatures import Signatures

result = Signatures.generate_signatures(privates, template, raw_transaction)
```
single key example:
```python
from bytom.signatures import Signatures

#### `create-key`

It is to create private key essentially, returns the information of key. The private key is encrypted in the file and not visible to the user.

##### Parameters

`Object`:

- `String` - *alias*, name of the key.
- `String` - *password*, password of the key.
- `String` - *language*, mnemonic language of the key.

Optional:
- `String` - *mnemonic*, mnemonic of the key, create key by specified mnemonic.

##### Returns

`Object`:

- `String` - *alias*, name of the key.
- `String` - *xpub*, root pubkey of the key.
- `String` - *file*, path to the file of key.

Optional:

- `String` - *mnemonic*, mnemonic of the key, exist when the request mnemonic is null.

##### Example

create key by random pattern:

```python
ret = api.create_key("alice", "123456", "en")
ret.alias       # alice
ret.xpub        # a85e6eccb22f4c5fdade905f9a969003a17b6f35c237183a4313354b819a92689d52da3bcfe55f15a550877e8d789bd2bb9620f46e5049ea36470ab1b588a986

#### `build-chain-transactions`

Build chain transactions. To solve the problem of excessive utxo causing the transaction to fail, the utxo merge will be performed automatically. Currently, only btm transactions are supported.Warning, this feature requires the mine pool bytomd software to be higher than v1.0.6.

##### Parameters

`Object`:

- `String` - *base_transaction*, base data for the transaction, default is null.
- `Integer` - *ttl*, integer of the time to live in milliseconds, it means utxo will be reserved(locked) for builded transaction in this time range, if the transaction will not to be submitted into block, it will be auto unlocked for build transaction again after this ttl time. it will be set to 5 minutes(300 seconds) defaultly when ttl is 0.
- `Integer` - *time_range*, time stamp(block height)is maximum survival time for the transaction, the transaction will be not submit into block after this time stamp.
- `Arrary of Object` - *actions*:
  - `Object`:
    - `String` - *account_id* | *account_alias*, alias or ID of account.
    - `String` - *asset_id* | *asset_alias*, alias or ID of asset.
    - `Integer` - *amount*, the specified asset of the amount sent with this transaction.
    - `String`- *type*, type of transaction, valid types: 'spend_account', 'issue', 'spend_account_unspent_output', 'control_address', 'control_program', 'retire'.
    - `String` - *address*, (type is control_address) address of receiver, the style of address is P2PKH or P2SH.
    - `String` - *control_program*, (type is control_program) control program of receiver.
    - `String` - *use_unconfirmed*, (type is spend_account and spend_account_unspent_output) flag of use unconfirmed UTXO, default is false.
    - `Arrary of Object` - *arguments*, (type is issue and spend_account_unspent_output) arguments of contract, null when it's not contract.
        - `String` - *type*, type of argument, valid types: 'raw_tx_signature', 'data'.
        - `Object` - * raw_data*, json object of argument content.
            - `String` - *xpub*, (type is raw_tx_signature) root xpub. 
            - `String` - *derivation_path*, (type is raw_tx_signature) derived path. 
            - `String` - *value*, (type is data) string of binary value.

#### `build-chain-transactions`
Build chain transactions. To solve the problem of excessive utxo causing the transaction to fail, the utxo merge will be performed automatically. Currently, only btm transactions are supported.Warning, this feature requires the mine pool bytomd software to be higher than v1.0.6.


##### Parameters

`Object`:

- `String` - *base_transaction*, base data for the transaction, default is null.
- `Integer` - *ttl*, integer of the time to live in milliseconds, it means utxo will be reserved(locked) for builded transaction in this time range, if the transaction will not to be submitted into block, it will be auto unlocked for build transaction again after this ttl time. it will be set to 5 minutes(300 seconds) defaultly when ttl is 0.
- `Integer` - *time_range*, time stamp(block height)is maximum survival time for the transaction, the transaction will be not submit into block after this time stamp.
- `Arrary of Object` - *actions*:
  - `Object`:
    - `String` - *account_id* | *account_alias*, (type is spend_account) alias or ID of account.
    - `String` - *asset_id* | *asset_alias*, (type is spend_account, issue, retire, control_program and control_address) alias or ID of asset.
    - `Integer` - *amount*, (type is spend_account, issue, retire, control_program and control_address) the specified asset of the amount sent with this transaction.
    - `String`- *type*, type of transaction, valid types: 'spend_account', 'issue', 'spend_account_unspent_output', 'control_address', 'control_program', 'retire'.
    - `String` - *address*, (type is control_address) address of receiver, the style of address is P2PKH or P2SH.
    - `String` - *control_program*, (type is control_program) control program of receiver.
    - `String` - *use_unconfirmed*, (type is spend_account and spend_account_unspent_output) flag of use unconfirmed UTXO, default is false.
    - `Arrary of Object` - *arguments*, (type is issue and spend_account_unspent_output) arguments of contract, null when it's not contract.
      - `String`- *type*, type of argument, valid types: 'raw_tx_signature', 'data'.
      - `Object`- *raw_data*, json object of argument content.
        - `String`- *xpub*, (type is raw_tx_signature) root xpub.
        - `String`- *derivation_path*, (type is raw_tx_signature) derived path.
        - `String`- *value*, (type is data) string of binary value.

##### Returns

- `Object of raw_transaction` - *raw_transaction*, builded transactions.
- `Object of signing_instructions` - *signing_instructions*, Information used to sign a transactions.
##### Example

- `spend` - transaction type is spend
