I tried to save (and run) the script in both directions and run it using both ipython and python , but I don't see any difference. Are these file name extensions expandable?
ipython
python
Edit: difference between python and ipython
.ipy indicates that it is an IPython script. The only difference between IPython scripts and regular Python scripts is that IPython scripts can use IPython magic, such as %timeit , and run system commands like !echo Hi .
.ipy
%timeit
!echo Hi
