* Objectives
At the end of this tutorial, you will be able to,
- Retrieve your ipython history.
- View a part of the history.
- Save a part of your history to a file.
- Run a script from within ipython.
* Pre-requisite
Spoken tuorial on -
- Embellishing a Plot
* Exercise 1
Read through the documentation of =%hist= and find out how to
list all the commands between 5 and 10.
* Exercise 2
Change the label on y-axis to "y" and save the lines of code
accordingly
* Exercise 3
Use =%hist= and =%save= and create a script that has the function show()
in it.Run the script to produce the plot and display the same.
* Exercise 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 the history using =%hist= command.
- View only a part of history by passing an argument to %hist.
- Save the required lines of code in required order using %save command.
- 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
