Mixing Python and Bash in iPython

Question

I understand ! tells iPython to treat the expression as "Bashy", but how do I tell iPython to treat an expression as "Pythony" so I can mix the two together?

For example, if I have a list of folders, how do I cd into them by indexing into the list?

In [57]: x = !find . -type d
In [58]: !cd x[-1]
sh: line 0: cd: x[-1]: No such file or directory

iPython is not making the substitution for x[-1]

Answer 1

!cd {x[-1]}

If you want change current dir of ipython:

cd {x[-1]}

• jaynp: What's the functional difference between the first one and second one?
• clyfish: The first one forks a new process, so it won't change the ipython(it's parent)'s current dir.
