* Objectives
At the end of this tutorial, you will be able to,
- Retrieve the ipython history.
- View a part of the history.
- Save (relevant) parts of the history to a file.
- Run 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
In this tutorial, we have learnt to –
- Retrieve history using =%hist= command.
- View only a part of history by passing an argument to =%hist=.
- Sav the required lines of code in the required order using =%save=.
- Use =%run -i= command to run the saved script.
* Evaluation
1. How do you retrieve the recent 5 commands
- ``%hist``
- ``%hist -5``
- ``%hist 5``
- ``%hist 5-10``
2. How do you save the lines 2 3 4 5 7 9 10 11
- ``%save filepath 2-5 7 9-11``
- ``%save filepath 2-11``
- ``%save filepath``
- ``%save 2-5 7 9 10 11``
3. What will the command ``%hist 5 10`` display.
- The recently typed commands from 5 to 10 inclusive of
the history command
- The recently typed commands from 5 to 10 excluding
the history command
* Solutions
1. %hist 5
2. %save filepath 2-5 7 9-11
3. %hist 5 10
