    32 * Outline

    33   + Retrieving ipython history 

    34   + Viewing a part of the history 

    35   + Saving (relevant) parts of the history to a file

    36   + Running a script from within ipython 

    37 * Question 1

    38   Read through the documentation of ~%hist~ and find out how to list

    39   all the commands between 5 and 10

    40 * Solution 1

    41   #+begin_src python

    42     In []: %hist 5 10

    43   #+end_src

    44 * Question 2

    45   Change the label on y-axis to "y" and save the lines of code

    46   accordingly

    47 * Solution 2

    48   #+begin_src python

    49     In []: ylabel("y")

    50     In []: %save /home/fossee/example_plot.py 1 3-6 10

    51   #+end_src

    52 * Question 3

    53   Use =%hist= and =%save= and create a script that has show in it and

    54   run it to produce and show the plot.

    55 

    56 * Solution 3

    57   #+begin_src python

    58     In []: %hist 20

    59         

    60     In []: %save /home/fossee/show_included.py 1 3-6 8 10 13

    61     In []: %run -i /home/fossee/show_included.py

    62   #+end_src

    63 * Question 4

    64   Run the script without using the -i option. Do you find any

    65   difference?

    66 * Solution 4

    67   We see that it raises ~NameError~ saying the name ~linspace~ is not

    68   found.

    69 * Summary

    70   + Retreiving history using =%hist= command

    71   + Vieweing only a part of history by passing an argument to %hist

    72   + Saving the required lines of code in required order using %save

    73   + Using %run -i command to run the saved script

    74 

    75 * Thank you!
