* Outline
  + Retrieving ipython history 
  + Viewing a part of the history 
  + Saving (relevant) parts of the history to a file
  + Running a script from within ipython 
* Question 1
  Read through the documentation of ~%hist~ and find out how to list
  all the commands between 5 and 10
* Solution 1
  #+begin_src python
    In []: %hist 5 10
  #+end_src
* Question 2
  Change the label on y-axis to "y" and save the lines of code
  accordingly
* Solution 2
  #+begin_src python
    In []: ylabel("y")
    In []: %save /home/fossee/example_plot.py 1 3-6 10
  #+end_src
* Question 3
  Use =%hist= and =%save= and create a script that has show in it and
  run it to produce and show the plot.

* Solution 3
  #+begin_src python
    In []: %hist 20
        
    In []: %save /home/fossee/show_included.py 1 3-6 8 10 13
    In []: %run -i /home/fossee/show_included.py
  #+end_src
* Question 4
  Run the script without using the -i option. Do you find any
  difference?
* Solution 4
  We see that it raises ~NameError~ saying the name ~linspace~ is not
  found.
* Summary
  + Retreiving history using =%hist= command
  + Vieweing only a part of history by passing an argument to %hist
  + Saving the required lines of code in required order using %save
  + Using %run -i command to run the saved script

* Thank you!
