* Objectives
At the end of this tutorial, you will be able to,
- invoke the ~ipython~ interpreter.
- quit the ~ipython~ interpreter.
- navigate in the history of ~ipython~.
- use tab-completion.
- look-up documentation of functions.
- interrupt incomplete or incorrect commands.
* Question 1
1. Type =ab= and hit tab to see what happens.
2. Next, just type =a= and hit tab to see what happens.
* Question 2
Look-up the documentation of =round= and see how to use it
* Question 3
Check the output of
#+begin_src python
round(2.48)
round(2.48, 1)
round(2.48, 2)
round(2.484)
round(2.484, 1)
round(2.484, 2)
#+end_src
* Solution 3
We get 2.0, 2.5 and 2.48, which are what we expect.
* Question 4
1. Type =round(2.484=, and hit enter and then cancel the command
using Ctrl-C.
2. Then, type the command, =round(2.484, 2)= and resume
the video.
* Summary
In this tutorial, we have learnt to –
- invoke the ~ipython~ interpreter by typing ipython.
- quit the ~ipython~ interpreter by using ~Ctrl-d~.
- navigate in the history of ~ipython~ by using the arrow keys.
- use tab-completionto work faster.
- see the documentation of functions using question mark.
- interrupt using ~Ctrl-c~ when we make an error.
* Evaluation
1. Which key combination quits ``ipython``?
- Ctrl + C
- Ctrl + D
- Alt + C
- Alt + D
2. Which character is used at the end of a command, in Ipython to
display the documentation.
- under score (_)
- question mark (?)
- exclamation mark (!)
- ampersand (&)
* Solutions
1. Ctrl + D
2. question mark (?)
