rpython

My question is: How can I change the python version to anaconda 3.5 and can use modules that have installed in anaconda in RStudio. I'm using RStudio Version 0.99.891 R version 3.2.3 (2015-12-10) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: OS X 10.11.3 (El Capitan) and I have installed Anaconda3, set python 3.5 as default python version. $ python Python 3.5.1 |Anaconda custom (x86_64)| (default, Dec 7 2015, 11:24:55) However, in RStudio, system("python --version") Python 2.7.10 I tried to change it by following method: Sys.setenv(PATH = paste("/Users/UserName/anaconda3/bin",

I am using the python package pymongo to retrieve data from a mongodb database. >>> r = collection.find() # returns an object of class 'Cursor' Then I convert to a list >>> l = list(r) # returns a 'list' of 'dict' here is what print(l) returns: >>> [{u'date': datetime.datetime(2009, 11, 10, 10, 45), u'_id': 1, u'name': u'name1', u'value': 11},{u'date': datetime.datetime(2013, 11, 10, 10, 45), u'_id': 2, u'name': u'name2', u'value': 22}] Now I need to convert to JSON so that I can manipulate it. >>> json.dumps(l) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr

(Or, "Can PyPy/RPython be used to compile/translate Python to C/C++ without requiring the Python runtime ?") I have tried to comprehend PyPy with its RPython and its Python, its running and its compiling and its translating, and have somewhat failed. I have a hypothetical Python project (for Windows); I would like to keep its size down, in the order of a hundred kilobytes (O.N.O.) rather than the several megabytes that using py2exe entails (after UPX). Can I use PyPy 1 in any way to produce a standalone executable which does not depend on Python26.dll? If I can, does it need to follow the
