A python implementation of [web3.js](https://github.com/ethereum/web3.js)

## Goals

* Python 2.7, 3.4, 3.5 support
* Provide a feature-for-feature python implementation of Web3.js


# API

## `web3`

### `web3.sha3`

```python
>>> web3.sha3(b'some text')
'46ba1b442d3606a3437800ee7ae5a0249756405e676739b46aa8f6e85b13fe2b'
>>> web3.sha3('0x80', encoding='hex')
'56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421'
```


## `web3.eth`

### `web3.eth.iban`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK")
<web3.eth.iban.Iban at 0x107301dd8>
```


#### `web3.eth.iban.fromAddress`

```python
>>> web3.eth.iban.fromAddress('0x00c5496aee77c1ba1f0854206a26dda82a81d6d8').toString()
'XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS'
```


#### `web3.eth.iban.fromBban`

```python
>>> web3.eth.iban.fromBban('ETHXREGGAVOFYORK').toString()
'XE81ETHXREGGAVOFYORK'
```


#### `web3.eth.iban.createIndirect`

```python
>>> web3.eth.iban.createIndirect({
... 'institution': "XREG",
... 'identifier': "GAVOFYORK"
... }).toString()
'XE81ETHXREGGAVOFYORK'
```


#### `web3.eth.iban.isValid`

```python
>>> web3.eth.iban.isValid("XE81ETHXREGGAVOFYORK")
True

>>> web3.eth.iban.isValid("XE82ETHXREGGAVOFYORK")
False # false, cause checksum is incorrect

web3.eth.iban("XE81ETHXREGGAVOFYORK").isValid()
True
```


#### `web3.eth.iban.isDirect`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK").isDirect()
False
```


#### `web3.eth.iban.isIndirect`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK").isIndirect()
True
```


#### `web3.eth.iban.checksum`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK").checksum()
'81'
```


#### `web3.eth.iban.institution`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK").institution()
'XREG'
```


#### `web3.eth.iban.client`

```python
>>> web3.eth.iban("XE81ETHXREGGAVOFYORK").client()
'GAVOFYORK'
```


#### `web3.eth.iban.address`

```python
>>> web3.eth.iban('XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS').address()
'00c5496aee77c1ba1f0854206a26dda82a81d6d8'
```


#### `web3.eth.iban.toString`

```python
>>> web3.eth.iban('XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS').toString()
'XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS'
```
