invalid syntax at python manage.py deploy

[Andrej1A]

I've followed the installation process and everything was prepared right on the target system with a clean Debian 9 machine. I've started the script out of my Mac OS X with Python 3.7.1 from my virtualenv.
After the fab bootstrap_ansible went through I've started the command python manage.py deploy and got the following error message:

SyntaxError: invalid syntax

I'm just a beginner with python, but after some research how to print a string with parameter it looks like the line:
print "number of hosts: %s" % str(len(inventory.list_hosts()))

should be look like the following line:
print("number of hosts: %(s)" % str(len(inventory.list_hosts())))

Hi Andre. The second syntax you refer is the Python3 one. The first syntax is for Python before 3. It looks like this package has no support for Python3.

Hi Daniel,
Thank you. I've just later seen that this tool is not up to date and the last commit is 4 years old.
