    32 * Outline

    33   + invoke the ~ipython~ interpreter

    34   + quit the ~ipython~ interpreter

    35   + navigate in the history of ~ipython~

    36   + use tab-completion

    37   + look-up documentation of functions

    38   + interrupt incomplete or incorrect commands

    39 * Question 1

    40   Type =ab= and hit tab to see what happens. Next, just type =a= and

    41   hit tab to see what happens.

    42 * Solution 1

    43   =ab= tab completes to =abs= and =a<tab>= gives us a list of all the

    44   commands starting with a.

    45 * Question 2

    46   Look-up the documentation of =round= and see how to use it.

    47 * Solution 2

    48   =round?=

    49 * Question 3

    50   Check the output of

    51   #+begin_src python

    52     round(2.48)

    53     round(2.48, 1)

    54     round(2.48, 2)

    55     

    56     round(2.484)

    57     round(2.484, 1)

    58     round(2.484, 2)

    59   #+end_src 

    60   Look-up the documentation of =round= and see how to use it.

    61 * Solution 3

    62   We get 2.0, 2.5 and 2.48, which are what we expect. 

    63 * Question 4

    64   Try typing =round(2.484=, and hit enter. and then cancel the command

    65   using Ctrl-C. Then, type the command, =round(2.484, 2)= and resume

    66   the video.

    67 * Solution 4

    68   #+begin_src python

    69     round(2.484 

    70     ^C

    71     

    72     round(2.484, 2)

    73   #+end_src 

    74 

    75 

    76 

    77 * Summary

    78   + invoking and quitting the ~ipython~ interpreter

    79   + navigating the history

    80   + using tab-completion to work faster

    81   + looking-up documentation using ~?~

    82   + sending keyboard interrupts using ~Ctrl-C~

    83 

    84 * Thank you!
