can't Transaction btc

[reynoldxu]

Hi,I;m just try pybitcointools but when i try to send btc to another address,it failed

I replaced priv = '???' instead sha256('some big long brainwallet password'),but error occoured when the 3rd sign as following:

tx3 = sign(tx2,1,priv)
  File "C:\Python27\lib\site-packages\pybitcointools\transaction.py", line 252, in sign
    signing_tx = signature_form(tx,i,mk_pubkey_script(address))
  File "C:\Python27\lib\site-packages\pybitcointools\transaction.py", line 104, in signature_form
    return serialize(signature_form(deserialize(tx),i,script))
  File "C:\Python27\lib\site-packages\pybitcointools\transaction.py", line 107, in signature_form
    newtx["ins"][i]["script"] = script
IndexError: list index out of range

i'm confused about sign(tx,i,priv),but i think according to the example ,the Index is correct,where's the problem?

The btc address is 1CtpwCtuWh7puJFkvXYMZNWaFD9rdG4YrT

Thanks,

seems that the priv key is not right and cant import into bitcoin-qt

>>> priv = sha256('hello_xmh@shnu')
>>> priv
'1af56f41c4edf512d4b76e2f9be72966fc1c81324adcf6d13036fd0c12f7121a'
>>> pub = privtopub(priv)
>>> pub

>>> addr = pubtoaddr(pub)
>>> addr
'1Pih9FmU3HN7JseN3Ca4reuq6ds1qvX6gx'
>>>

Invalid private key (code -5)

when i use the priv key to send btc ,failed ,the same:

>>> h = history(addr)
>>> h
[{'output': u'914bd4c98c944a280f59d48841797a95cc1f402ef400e7e9d392e67feb67c899:1', 'block_height': 289844, 'value': 100000, 'address': u'1Pih9FmU3HN7JseN3Ca4reuq6ds1qvX6gx'}]
>>> outs = [{'value': 1000, 'address': '1NLndq3B15EfGv8GQthxhDzFNQGPbsWQyg'}]
>>> tx = mktx(h,outs)
>>> tx2 = sign(tx,0,priv)
>>> tx3 = sign(tx2,1,priv)

Traceback (most recent call last):

    tx3 = sign(tx2,1,priv)

    newtx["ins"][i]["script"] = script
IndexError: list index out of range

well,the priv key should be convert to WIF formart than it could be import into bitcoin-qt.

working on the error:

tx3 = sign(tx2,1,priv)

newtx["ins"][i]["script"] = script
IndexError: list index out of range

Can you give me the tx that you're signing? Maybe the transaction doesn't have two inputs (inputs are zero-indexed so the first input is really input 0).

[reynoldxu]

Yes, it has only one inputs(i use a new address for test so ,it has only one input)
Tx bin is
010000000199c867eb7fe692d3e9e700f42e401fcc957a794188d4590f284a948cc9d44b910100000000ffffffff01e8030000000000001976a914ea18a38e2119616d05fbb31a2138f43565608d7c88ac00000000
Tx json is
{'locktime': 0, 'outs': [{'value': 1000, 'script': '76a914ea18a38e2119616d05fbb31a2138f43565608d7c88ac'}], 'version': 1, 'ins': [{'script': '', 'outpoint': {'index': 1, 'hash': '914bd4c98c944a280f59d48841797a95cc1f402ef400e7e9d392e67feb67c899'}, 'sequence': 4294967295L}]}
