IPython: redirecting output of a Python script to a file (like bash >)

Question

I have a Python script that I want to run in IPython. I want to redirect (write) the output to a file, similar to:

python my_script.py > my_output.txt
         


        

Answer 1

For just one script to run I would do the redirection in bash

ipython -c "execfile('my_script.py')" > my_output.txt

On python 3, execfile does not exist any more, so use this instead

ipython -c "exec(open('my_script.py').read())" > my_output.txt

Be careful with the double vs single quotes.
