bpython configuration - importing numpy and matplotlib by default

Question

Is it possible to start the bpython interpreter so that it always runs some custom commands when it launches?

In my case I simply want to do:

import numpy as np
import matplotlib.pyplot as plt

I can't see anything in the docs. Anyone know a way?

Answer 1

It is written in the docs, just not clearly labelled as such at: http://docs.bpython-interpreter.org/django.html

Gist of it is you can have an environment variable called PYTHONSTARTUP. bpython will execute this file before you get dropped in the interpreter.

Answer 2

While ikanobori's answer is the way to go here, I thought I show another simple alternative.

import numpy as np
import matplotlib.pyplot as plt
import bpython
bpython.embed(locals_=locals())

This will start up the bpython REPL and load in the local variables and other symbols. This would be useful if you wanted to have more than one customized shell.
