quantecon

QuantEcon.py

A high performance, open source Python code library for economics

  from quantecon.markov import DiscreteDP
  aiyagari_ddp = DiscreteDP(R, Q, beta)
  results = aiyagari_ddp.solve(method='policy_iteration')

Installation

Before installing quantecon we recommend you install the Anaconda Python distribution, which includes a full suite of scientific python tools. Note: quantecon is now only supporting Python version 3.5+. This is mainly to allow code to be written taking full advantage of new features such as using the @ symbol for matrix multiplication. Therefore please install the latest Python 3 Anaconda distribution.

Next you can install quantecon by opening a terminal prompt and typing

pip install quantecon

Usage

Once quantecon has been installed you should be able to import it as follows:

import quantecon as qe

You can check the version by running

print(qe.__version__)

If your version is below what’s available on PyPI then it is time to upgrade. This can be done by running

pip install --upgrade quantecon
