Python wrapper around the `solc` Solidity compiler.


# Dependency

This library requires the `solc` executable to be present.

solc 0.3.5 or newer is required. [solc installation instructions](http://solidity.readthedocs.io/en/latest/installing-solidity.html)

> Currently does not work with anything `0.4.x` or later.


# Quickstart

Installation

```sh
pip install py-solc
```

```python
>>> from solc import compile_source, compile_files, link_code
>>> compile_source("contract Foo { function Foo() {} }")
{
'Foo': {
'abi': [{'inputs': [], 'type': 'constructor'}],
'code': '0x60606040525b5b600a8060126000396000f360606040526008565b00',
