jsnap2py is broken in pip3.6

[nskalis]

Description of Issue/Question

jsnap2py breaks when it is installed via pip3.6

Setup

not relevant, even the --version is not working

Steps to Reproduce Issue

pip3.6 install jsnapy

Versions Report

$ jsnap2py --version
  File "/usr/bin/jsnap2py", line 30
    msg = "{{%s_%s}}" % (data)
                             ^
TabError: inconsistent use of tabs and spaces in indentation

Could you please fix it ? And please confirm once the fix is available in pip3.6 ?

when the tab issue gets resolved, then there is another issue:

$ jsnap2py -i jsnap.interfaces.conf -o jsnapy.interfaces.yaml
Traceback (most recent call last):
  File "/usr/bin/jsnap2py", line 125, in <module>
    if len(inputs) > 0:
TypeError: object of type 'map' has no len()

which is resolved by

inputs = list(map(msg_change, inputs))

in line 123
