 Most compilers for HLLs (solidity, serpent, viper, etc) on top of Ethereum have the option to output an ABI declaration for a program. This is a json object that looks something like this:
 
-    [{"name": "ecrecover(uint256,uint256,uint256,uint256)", "type": "function", "constant": false,
-     "inputs": [{"name": "h", "type": "uint256"}, {"name": "v", "type": "uint256"}, {"name": "r", "type": "uint256"}, {"name": "s", "type": "uint256"}],

-     "inputs": [{"name": "x", "type": "uint256", "indexed": false}, {"name": "y", "type": "uint256", "indexed": false}, {"name": "z", "type": "uint256", "indexed": false}]}]

 You can initialize an `abi.ContractTranslator` object to encode and decode data for contracts as follows:
 
-    true, false = True, False  
-    ct = abi.ContractTranslator(<json here>)  
-    txdata = ct.encode('function_name', [arg1, arg2, arg3])  
+```python
+true, false = True, False  
+ct = abi.ContractTranslator(<json here>)  
+txdata = ct.encode('function_name', [arg1, arg2, arg3])  
+```
 
 You can also call `ct.decode_event([topic1, topic2...], logdata)` to decode a log.
 
 ### RLP encoding and decoding
 
 For any transaction or block, you can simply do:
 
-    import rlp  
-    bindata = rlp.encode(<tx or block>)  
+```python
+import rlp  
+bindata = rlp.encode(<tx or block>)  
+```
 
 To decode:
 
-    import rlp  
-    from ethereum.transactions import Transaction  
-    rlp.decode(blob, Transaction)  
+```python
+import rlp  
+from ethereum.transactions import Transaction  
+rlp.decode(blob, Transaction)  
+```
 
 Or:
 
-    import rlp  
-    from ethereum.blocks import Block  
-    rlp.decode(blob, Block)  
+```python
+import rlp  
+from ethereum.blocks import Block  
+rlp.decode(blob, Block)  
+```
