== pycoin, ku, and tx
((("pycoin library")))The Python library https://github.com/richardkiss/pycoin[+pycoin+], originally written and maintained by Richard Kiss, is a Python-based library that supports manipulation of bitcoin keys and transactions, even supporting the scripting language enough to properly deal with nonstandard transactions.
The pycoin library supports both Python 2 (2.7.x) and Python 3 (3.3 and later) and comes with some handy command-line utilities, +ku+ and +tx+.
=== Key Utility (KU)
((("key utility (ku)", id="keyutil17")))The command-line utility +ku+ ("key utility") is a Swiss Army knife for manipulating keys. It supports BIP-32 keys, WIF, and addresses (bitcoin and alt coins). Following are some examples.
Create a BIP-32 key using the default entropy sources of GPG and _/dev/random_:

==== Transaction Utility (TX)
((("transaction utility (TX)", id="TX17")))
The command-line utility +tx+ will display transactions in human-readable form, fetch base transactions from pycoin's transaction cache or from web services (blockchain.info, blockcypher.com, blockr.io and chain.so are currently supported), merge transactions, add or delete inputs or outputs, and sign transactions.
Following are some examples.

Oops! We don't have web services set up. Let's do that now:
[source,bash]

$ export PYCOIN_CACHE_DIR PYCOIN_BTC_PROVIDERS
----
It's not done automatically so a command-line tool won't leak potentially private information about what transactions you're interested in to a third-party website. If you don't care, you could put these lines into your _.profile_.
Let's try again:

** can't validate transaction as source transactions missing

The final line appears because to validate the transactions' signatures, you technically need the source transactions. So let's add +-a+ to augment the transactions with source information:

((("", startref="TX17")))Now, let's look at unspent outputs for a specific address (UTXO). In block #1, we see a coinbase transaction to +12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX+. Let's use +fetch_unspent+ to find all coins in this address:
