ipython how to execute several history lines

Question

In ipython, we can use

_ih[32:39] 

To show history lines between 32 and 39. How can I directly execute these history lines?

Answer 1

You can execute code from previous sessions with %recall. See %recall documentation here.

#Execute all code from previous session. %recall ~1/  #Execute all code from two sessions previous the current session. %recall ~2/  #Execute lines 1 to 5 from previous session. %recall ~1/1-5 

Answer 2

I use the list notation:

exec In[34:36] 

also, if you use the edit function to edit a chunk, the Out list will have your code in it, so:

exec Out[35] 

And my favorite:

edit In[34:38] 

because I am a fat-fingered slob who can rarely get it right on the first try.

Answer 3

On recent versions of iPython you use the rerun magic-comand:

%rerun 32:39
