How to Make a Transaction in IOTA

from iota import *

api = Iota('https://host', 'SampleSeed')

pt = ProposedTransaction(address = Address('SampleOutput'), value = 100)

in_addy = Address('SampleInput') # 0 or more

ch_addy = Address('SampleChange') # 0 or 1

api.send_transfer(transfers = [ pt ], inputs = [ in_addy ], change_address = [ ch_addy ])
