66 | | -This is a second course in programming, building a previously |
67 | | -acquired basic understanding of programming in Python. In covering |
68 | | -more advanced programming, we will pay particular attention to objects |
69 | | -and abstraction as they occur in Python. Furthermore, we will do so |
70 | | -from a mathematician's perspective, understanding programming as a |
71 | | -process of defining and manipulating mathematical objects, and |
72 | | -scientifically testing and debugging the results. |

74 | | -How to do this course |
75 | | ---------------------- |
76 | | - |
77 | | -Programming, like mathematics, is a practical, problem solving discipline. It's |
78 | | -not possible to learn to program just by reading notes and watching lectures. To |
79 | | -learn to program you need to put the content of the course into practice by |
80 | | -writing code. The structure of this course is designed to help you to really |
81 | | -understand new concepts in programming by putting them into practice. Each week, |
82 | | -we run through the same cycle: |
83 | | - |
84 | | -1. Read the notes |
85 | | -2. Watch the videos |
86 | | -3. Do the quiz |
87 | | -4. Write the code |
88 | | - |
89 | | -The notes |
90 | | -......... |
91 | | - |
92 | | -All of the new material we cover in this course is presented in these notes. |
93 | | -Each chapter contains the material for one week of term, so in week :math:`n`, |
94 | | -you work through chapter :math:`n`. The notes always the starting point for your work. |
95 | | -Each chapter will introduce new concepts in programming, often tied back to |
96 | | -related mathematical concepts, and always illustrated by practical code |
97 | | -examples. Python has excellent `official online documentation |
98 | | -<https://docs.python.org/3/>`_, and we link to that throughout the text. |
99 | | -External links show up in orange while :ref:`internal links to other parts of |
100 | | -the notes <introduction>` are red. Sometimes we introduce counterexamples: |
101 | | -illustrations of code errors or bad implementation ideas. These will be flagged |
102 | | -with a big red cross: |
103 | | - |
104 | | -.. container:: badcode |
105 | | - |
106 | | - .. code-block:: python3 |
107 | | -
|
108 | | - print "Hello World" |
109 | | -
|
110 | | -Conversely, if it's necessary in context to highlight which approach is the |
111 | | -correct one, the code will come with a big green tick: |
112 | | - |
113 | | -.. container:: goodcode |
114 | | - |
115 | | - .. code-block:: python3 |
116 | | -
|
117 | | - print("Hello World") |
118 | | -
|
119 | | -At the end of each chapter there is a glossary containing key new concepts |
120 | | -introduced in that chapter. Always check the glossary and convince yourself that |
121 | | -you understand all the terms introduced there, this is a good check on whether |
122 | | -you have understood the chapter as a whole. However, there is more to learning |
123 | | -new concepts than just the vocabulary, so don't be tempted to skip reading the |
124 | | -chapter and just jump to the glossary! |
125 | | - |
126 | | -The chapters broadly alternate between introducing new programming concepts, |
127 | | -such as :ref:`objects <objects>`, :ref:`abstract data types |
128 | | -<abstract_data_types>`, or :ref:`inheritance <inheritance>`, and |
129 | | -covering various aspects of the craft of programming, such as :ref:`style |
130 | | -<inheritance>` and :ref:`debugging <debugging>`. In this way the course combines specific programming knowledge |
131 | | -with more general coding skills. |
132 | | - |
133 | | -The videos |
134 | | -.......... |
135 | | - |
136 | | -Throughout the notes are links to videos. These aren't typical lecture videos in |
137 | | -that they're not primarily focussed on delivering the new ideas in the course. |
138 | | -In particular, the videos don't set out to duplicate the delivery of the |
139 | | -material in the notes. Instead, the videos focus on putting the concepts into |
140 | | -practice, often by showing live coding sessions. Usually you'll want to watch |
141 | | -the video for a given section *after* reading the corresponding notes. |
142 | | - |
143 | | -The quizzes |
144 | | -........... |
145 | | - |
146 | | -Towards the end of each chapter is a link back to a quiz on Imperial's |
147 | | -Blackboard system. The quizzes are designed to allow you to convince yourself |
148 | | -that you've understood the material in the chapter. Sometimes they will simply |
149 | | -be multiple choice questions testing your understanding of the material, but |
150 | | -sometimes you will need to open up Python and try things out in order to work |
151 | | -out the right answer. The quizzes do not contribute to your module grade, but how |
152 | | -well you are doing on them is an indication of your progress on the module. |
153 | | - |
154 | | -The exercises |
155 | | -............. |
156 | | - |
157 | | -As we've already noted, really learning to program better is only achieved by |
158 | | -writing code. The core of each week's activities is therefore to put the new |
159 | | -concepts and programming structures you've learned into practice. The |
160 | | -programming exercises are given at the end of each chapter, just before the |
161 | | -glossary. Each time there will be a skeleton code available from |
162 | | -:ref:`GitHub Classroom <fons:github_classroom_exercise>` which provides the starting |
163 | | -point. Sometimes you might be asked to complete a piece of code while on other |
164 | | -occasions you'll need to write a whole Python module from scratch. Each set of |
165 | | -exercises will come with a matching set of tests. These are small programs which |
166 | | -check whether your code produces the correct responses to a range of inputs. |
167 | | -Tests like this provide immediate feedback and enable you to know how you are |
168 | | -doing without having to wait for code to be submitted and marked. |
169 | | - |
170 | | -.. note:: |
171 | | - |
172 | | - Solutions to exercises will not be issued. The notes and accompanying |
173 | | - example code contain examples of the same programming constructs that the |
174 | | - exercises require you to implement, and the tests provide a mechanism to |
175 | | - know when you have a correct answer. There are also help mechanisms via the |
176 | | - course forum and the lab sessions. Issuing solutions to problems would |
177 | | - simply encourage students to study the solutions rather than write code, and |
178 | | - the only way to learn to program is to write code. |
179 | | - |
180 | | -Assessment |
181 | | -.......... |
182 | | - |
183 | | -The weekly quiz and exercises are not assessable: they are formative activities |
184 | | -designed to help you learn the module. Instead, the module will be assessed by |
185 | | -two controlled programming assessments, effectively programming exams. The first |
186 | | -programming assessment will be held in week 7 and will be worth 20% of the |
187 | | -marks for the course. This provides an opportunity to receive feedback in the |
188 | | -middle of the term, and is a practice for the main exam. The :ref:`course contents for |
189 | | -week 7 <midterm>` will comprise practice programming exercises for this midterm test. |
190 | | -The second programming assessment will be held in the main May exam period and |
191 | | -will count for the other 80% of the course. |
192 | | - |
193 | | -The instructions and skeleton code for the programming exercises will be |
194 | | -released at a fixed time on GitHub Classroom, and the code which you have |
195 | | -committed to GitHub by the end of the allotted time will be marked. |
196 | | - |
197 | | -The exam questions will be similar to the weekly exercises in the course, |
198 | | -and may include new programmes to write from specification, modifications or |
199 | | -extensions to be made to code which is provided, and debugging exercises in |
200 | | -which defective code is provided which you need to correct. Marks will be |
201 | | -allocated both for the functional correctness of the code written, and for |
202 | | -good style and following Python coding conventions. |
