|
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 |
|

|
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~ |
|
