NEO Smart Contract Programming - Setting up Neo-Python Dev Environment

Neo platform is an exciting place to create smart contracts and Dapps. I am creating this section to log my efforts to setup and get going with Neo Smart Contract development. I am opting to use the neo-python project by COZ to get started as i found other methods to be more tedious and under documented in certain areas.

Initial steps :

  1. I created a virtual machine with ubuntu v18 with vmware tool. (Just to keep my development environment isolated from my global environment.One could opt to run on global environment)

  2. I am following the instructions from this link ( https://github.com/CityOfZion/neo-python/blob/master/README.rst ).

     Logging the efforts:
     1.Installing python v3.6 and levelDB using the below command
         sudo apt-get install python3.6 python3.6-dev python3-pip python3-venv libleveldb-dev libssl-dev g++
     2.creating a Directory with mkdir mydirectory and entering the directory with cd directory
     3.creating python 3.6 virtual machine.
        python3.6 -m venv venv 
     4.opening the virtual machine to access the command prompt.
       $ source venv/bin/activate
     5.Installing neo python with PyPi using pip
       (venv) $ pip install neo-python
     6.After installation we'll have to bootstrap the testnet to test our build.
       (venv) $ np-bootstrap 
       its going to take a while to dowload complete testnet so grab a coffee or reach me in discord/telegram 
       for a chat 
       
       **@sozhan** is my handle

Good to know for me EOS and NEO both projects are the best at the moment am more into EOS now
trying to understand it but after that i will move to NEO so will be glad if you share your experience here.

Hi there, I have lately started being interested in both these projects,are you still working on them?
How do you think they are performing?
