Handcrafting guide broken for several snippets

bigchaindb-driver version: 0.4.0
BigchainDB version: 1.0.1
MongoDB version: 3.4.6
Python version: 3.5.2
Operating System: Ubuntu 16.04(Xenial)

Description

Handcrafting guide seems to be broken. I tried to follow the steps but ran into multiple issues one of those is #313.

A lot of code snippets are broken as well and I haven't been able to send prepare, fulfil and send a transaction that turns out to be valid. All the transactions that I try to make after adding workarounds(mentioned in #313) go into the backlog state.

What I Did

Follow the Handcrafting Transactions(from github master))

Also tried the [Handcrafting Transactions(from website)]

One of the snippets that doesn't work is, there are multiple other instances of this captured in #313:

Section: The Fulfilled Transaction
