This document summarizes key Python concepts including: 1. The interactive shell and scripts are two methods for running Python code. The interactive shell runs code line by line using python while scripts run entire files using python filename.py. 2. Python supports basic data types like numbers, strings, and lists. Numbers include ints and floats. Strings can be enclosed in single or double quotes. Lists allow storing multiple values and accessing via indexes. 3. Control flow statements like if/elif/else and for loops allow conditionally executing blocks of code. If statements check conditions and elif/else provide optional else blocks. For loops iterate over lists, strings, and ranges of numbers.

Django class based views
Django class based viewsjustinvoss This document discusses class-based views in Django. It begins with an introduction to Python classes and functions. It then explains regular Django views as functions that take a request and return a response. Generic views are introduced as reusable view functions provided by Django that implement common patterns like listing and detail views. The document argues that class-based views allow for more customization and code reuse by controlling view behavior through inheritance and method overrides. Examples are provided of customizing generic views and listing views as classes rather than functions. While class-based views enable deeper customization, limitations remain in terms of flexibility and potential threading issues.

3) Find the 10th Fibonacci number using a recursive function;
4) Draw the graph of a binary entropy function using np.log2().
Py lecture5 python plots
Py lecture5 python plotsYoshiki Satotani Matplotlib is a 2D plotting library for Python that can generate publication-quality figures in both hardcopy and interactive formats. The document provides examples of using Matplotlib to plot lines, histograms, pie charts, scatter plots, subplots, and mathematical functions. Additional resources are also listed for learning more about Matplotlib and an example dataset on apple production by variety.
PyLecture4 -Python Basics2-
PyLecture4 -Python Basics2-Yoshiki Satotani The document provides examples and explanations of Python concepts including:
1. Printing "Hello World" with a function.
2. Using lists, including accessing/setting values and adding/removing elements.
3. Using range to generate lists of numbers.
4. Creating and manipulating dictionaries.
5. Logical operators and if/else statements.
6. For loops for iterating over lists and ranges.
7. Defining recursive functions.
PyLecture2 -NetworkX-
PyLecture2 -NetworkX-Yoshiki Satotani The document discusses using Python and the NetworkX library to generate and analyze graphs. It shows how to import NetworkX, generate different types of graphs including paths, cycles, complete graphs and random graphs. It also demonstrates functions for analyzing graphs like calculating node degrees, edges, average path length and density. The document then discusses using the Twitter API via the Tweepy library to generate a follower graph in Python starting from a seed user.
PyLecture3 -json-
PyLecture3 -json-Yoshiki Satotani This document provides an overview of dictionaries and JSON in Python. It explains that dictionaries are a compound data type that map keys to values, like maps or associative arrays in other languages. JSON is a lightweight data format that is easy for humans to read and write, and easy for machines to parse. It shows examples of loading JSON data from a string, file, and URL. It also gives examples of querying eBay and GitHub APIs and saving/loading NetworkX graphs.
PyLecture1 -Python Basics-
- 2. Installation Create easy networks and show them
- 3. The interactive shell vs scripts › Running the interactive shell just type ‘python’ › Running a script type ‘python <script-name>’ (e.g. python script.py)
- 4. Numbers >>> 2 + 2 4 >>> 50 - 5*6 20 >>> (50 - 5.0*6) / 4 5.0 >>> 8 / 5.0 1.6 >>> 5 % 3 2 >>> 2 ** 8 256 › int – the integer values(2, 7, 20…) › float – the ones with a fractional part(1.0, 3.14…) › int / int -> int (5 / 3 = 1, not 1.66…) › int / float -> float, float / int -> float
- 5. Strings › Can be enclosed in single quotes (i.e. ‘…’) or double quotes (i.e. “…”) >>> “Hello Python!” ‘Hello Python!’ >>> print “Hello”, “Python”, 2.7 Hello Python 2.7
- 6. Lists – compound data type >>> [1,2,3,5][0] 1 >>> [1,2,3,5][2] 3 >>> [1,2,3,5][-1] 5 >>> [1,2,3,5][2:] [3, 5] >>> [1,2,3,5][:2] [1, 2] >>> len([1,2,3,5]) 4 >>> range(4) [0,1,2,3] (Creates a 4-value list starts with 0)
- 7. The equal sign(=) is used to assign a value to a variable >>> width = 5 >>> height = 10 >>> print ‘Triangle area:’, (width * height / 2.0) Triangle area: 25.0
- 8. >>> raw_input(‘Please enter something: ’) Please enter something: <your response> ‘<your response>’ – string type! >>> x = int(raw_input(‘Enter an integer: ‘)) Enter an integer: -1 >>> x -1
- 9. Two methods › the interactive shell › scripts Basic data types › Numbers › Strings › Lists range() function Variable Inputs from your keyboard
- 10. if, elif, else statements >>> x = 42 >>> if x < 0: … print ‘Negative’ …elif x == 0: … print ‘Zero’ …else: … print ‘Positive’ … Positive
- 11. You can skip elif and/or else. >>> if x < 0: … print ‘Negative’ … else: … print ‘Not negative’ … Not negative >>> if x > 0: … print ‘Positive’ … Positive
- 12. for statements >>> words = [‘Mac’, ‘Linux’, ‘Windows’] >>> for w in words: … print w … Mac Linux Windows >>> >>> for i in range(len(words)): … print words[i] …
- 13. Generates a list with for statement(s) >>> [4 * x for x in range(5)] [0, 4, 8, 12, 16] >>> [4 * x for x in range(5) if x % 2 == 0] [0, 8, 16] >>> [4*x*y for x in range(1,3) for y in range(1,3)] [4, 8, 8, 16]
- 14. Control flow statements › if statements › for statements List comprehension
