How to log everything that occurs in a Python interactive shell session?

Question

I\'d like to have real-time access to both interpreter input and error and standard output. Preferably this information would be written to a file, so that I can poll the fi

Answer 1

I've only tested this in python2.7. I don't have 3 handy.

import code
import sys

class Tee(object):

  def __init__(self, log_fname, mode='a'):
    self.log = open(log_fname, mode)

  def __del__(self):
    # Restore sin, so, se
    sys.stdout = sys.__stdout__
    sys.stdir = sys.__stdin__
    sys.stderr = sys.__stderr__
    self.log.close()

  def write(self, data):
    self.log.write(data)
    sys.__stdout__.write(data)

  def readline(self):
    s = sys.__stdin__.readline()
    self.log.write(s)
    return s

# Tie the ins and outs to Tee.
sys.stdout = sys.stderr = sys.stdin = Tee('consolelog.dat', 'w')

console = code.InteractiveConsole()
console.interact()
