32 * Outline |
|
33 - Defining Sets |
|
34 - Operations on sets |
|
35 |
|
36 * Question 1 |
|
37 Given a list of marks, ~marks = [20, 23, 22, 23, 20, 21, 23]~ list |
|
38 all the duplicates |
|
39 * Solution 1 |
|
40 #+begin_src python |
|
41 marks = [20, 23, 22, 23, 20, 21, 23] |
|
42 marks_set = set(marks) |
|
43 for mark in marks_set: |
|
44 marks.remove(mark) |
|
45 |
|
46 # we are now left with only duplicates in the list marks |
|
47 duplicates = set(marks) |
|
48 #+end_src |
|
49 * Summary |
|
50 You should now be able to -- |
|
51 + make sets from lists |
|
52 + input sets directly |
|
53 + perform operations like union, intersection, symmetric difference |
|
54 + check if a subset of another |
|
55 + check containership, length and other properties similar to lists |
|
56 * Thank you! |
