Next, just type =a= and hit tab to see what happens. * Solution 1 =ab= tab completes to =abs= and =a= gives us a list of all the commands starting with a. * Question 2 Look-up the documentation of =round= and see how to use it. * Solution 2 =round?= * 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 Look-up the documentation of =round= and see how to use it. * Solution 3 We get 2.0, 2.5 and 2.48, which are what we expect. * Question 4 Try typing =round(2.484=, and hit enter. and then cancel the command using Ctrl-C. Then, type the command, =round(2.484, 2)= and resume the video. * Solution 4 #+begin_src python round(2.484 ^C round(2.484, 2) #+end_src * 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. Ipython is a programming similar to Python? True or False 2. Which key combination quits ``ipython``? - Ctrl + C - Ctrl + D - Alt + C - Alt + D 3. Which character is used at the end of a command, in Ipython to display the documentation. - under score (_) - question mark (?) - exclamation mark (!) - ampersand (&) * Solution 1. False 2. Ctrl + D 3. question mark (?) * Acknowledgement #+begin_latex \begin{block}{} \begin{center} \textcolor{blue}{\Large THANK YOU!} \end{center} \end{block} \begin{block}{} \begin{center} For more Information, visit our website\\ \url{http://fossee.in/} \end{center} \end{block} #+end_latex
