[IPython-user] questions about shell capture

[Steven Bluen]

I want to assign the output of a bash shell command to a list value in IPython. But when I try it, I get this error.





In [13]: a[1]=!ls

------------------------------------------------------------

   File "<ipython console>", line 1

     a[1]=!ls

          ^

SyntaxError: invalid syntax



This statement doesn't work either:

a=len(!ls)



But this one does work:

a=!ls



Can someone please explain how to get the other statements to work?
