using jSON--please help!

[ghost]

Hi I am trying to use a json package in python.

I confirmed that my iron-python installation folder already comes with a json.py file.
But dynamo does not seem to recognize it. Adding a 'import json' causes an error in the script node. I am not doing it correctly? It works with other packages like 'itertools'

You should add Python libraries path to sys.path before importing the library

import sys
sys.path.append(r"C:\Program Files (x86)\IronPython 2.7\Lib")

import json

Thanks, this worked.

I have two follow up questions:

1- Wondering why adding to path is required. For example, I can import itertools with
just the import statement. Both itertool and json live in the same
directory. Or is it that itertool is coded in by default?
2- the script editor in dynamo does not show a list available methods for
json after the dot operator.. for example: ' json.loads('["foo",
{"bar":["baz", null, 1.0, 2]}]'). It does that just fine for itertools.

If you check sys.path you'll see that Python node in dynamo doesn't have a path to IronPython folder. You need to add it yourself so it can find the libraries.

I don't know how auto-complete works in Python node. It's probably broken but it shouldn't change how your code works.

reopening - as I did not notice the last question was about the python autocomplete.
