* 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!
