"isinstance" bug in nest.py

[dohmatob]

Description

Running the example http://www.nest-simulator.org/py_sample/twoneurons/ yields the following error traceback

...
  File "/home/elvis/anaconda2/envs/py3k/lib/python3.6/site-packages/nest.py", line 4
    if isinstance(each_item, indent = False ,list):
                                            ^
SyntaxError: positional argument follows keyword argument

@dohmatob This looks strange. There should not be any file nest.py in a NEST installation, and the line if isinstance(each_item... is not in NEST code.

It seems there is another nest library which is not nest-simulator. and you installed it with this command :
pip install nest
simply uninstall it:
pip uninstall nest
and follow the installation from the nest documentaion.
