python-bitshares: How to derive transaction ids
Some developers might have noticed that python-graphene and python-bitshares are still pretty much in development.
That said, I finally got to figure out (thanks to @abitmore) how to derive transaction ids from a given transaction on the blockchain and quickly implemented this feature in python-bitshares.
From release 0.5.7 of python-graphene and with the next release of python-bitshares (currently in develop branch), you can obtain the transaction id of any transaction by simply:
from bitshares.block import Block
from bitsharesbase.signedtransactions import Signed_Transaction
block = Block(23743383)
tx = Signed_Transaction(**block["transactions"][2])
print(tx.id)
The Signed_Transaction expects keywords with identical names as on the blockchain, which explains the use of ** in front of the dictionary.
The attribute .id of tx is an internal method that derives the transaction id accordingly.
The resulting ids are similar to the ones derived by the cli_wallet and indexed by cryptofresh.com.
In the future, I intend to put more updates on libraries whenever nice features are included (such as the proposal subsystem of pybitshares which was released without further announcements ;D)
Have fun.

i really like your post and i enjoy it very with all post 👍
I appreciate your efforts to BTS community!
I wish i understood this stuff better. Guess i just gotta keep digging
I really wanna know more about these. I'd tried creating a wallet some time back, I couldnt. lol
i love python
Excellent work! I'll integrate these changes into the HUG REST API in the near future, keep up the great work!
Interesting, Hadn't realized python works with this kind of stuff. Maybe cuz I'm living under a rock..idk XD

Maximum work from python will certainly develop better bitshare and will support great progress
@xeroc
hmmm okay! thanks
