Gui. Encryption Examples for Python. Encrypted SQLite Databases with Python and SQLCipher. SQLCipher, created by Zetetic, is an open-source library that provides transparent 256-bit AES encryption for your SQLite databases.
SQLCipher is used by a large number of organizations, including Nasa, SalesForce, Xerox and more. The project is open-source and BSD licensed. Best of all, there are open-source python bindings. In this post, I'll show how to get started writing Python scripts that interact with encrypted SQLite databases. For users of the peewee ORM, I will demonstrate the usage of the sqlcipher playhouse module. Building SQLCipher Let's get started by cloning the most recent version of the SQLCipher library and installing it on our system. $ git clone $ cd sqlcipher To compile SQLCipher, we will link against OpenSSL's libcrypto, so make sure you have OpenSSL installed before proceeding.
. $ . You should now be able to fire up the sqlcipher shell, which by default is connected to an in-memory database: Kicking the tires on SQLCipher Building pysqlcipher That's it! Links. A thorough guide to SQLite database operations in Python. -- written by Sebastian Raschka on March 7, 2014 After I wrote the initial teaser article "SQLite - Working with large data sets in Python effectively" about how awesome SQLite databases are via sqlite3 in Python, I wanted to delve a little bit more into the SQLite syntax and provide you with some more hands-on examples.
Sections • Connecting to an SQLite database • Creating a new SQLite database - Overview of SQLite data types - A quick word on PRIMARY KEYS: • Adding new columns • Inserting and updating rows • Creating unique indexes • Querying the database - Selecting rows • Security and injection attacks • Date and time operations • Printing a database summary • Conclusion.

This is version 0.45 of a collection of simple Python exercises constructed (but in many cases only found and collected) by Torbjörn Lager (email@example.com).
Most of them involve characters, words and phrases, rather than numbers, and are therefore suitable for students interested in language rather than math. Very simple exercises Higher order functions and list comprehensions. 1.4. Matplotlib: plotting — Scipy lecture notes. 1.4.2.
Simple plot Tip In this section, we want to draw the cosine and sine functions on the same plot. Starting from the default settings, we’ll enrich the figure step by step to make it nicer. First step is to get the data for the sine and cosine functions: Alternative Python Implementations. This site hosts the "traditional" implementation of Python (nicknamed CPython).
A number of alternative implementations are available as well, namely IronPython (Python running on .NET)Jython (Python running on the Java Virtual Machine)PyPy (A fast python implementation with a JIT compiler)Stackless Python (Branch of CPython supporting microthreads) Other parties have re-packaged CPython. These re-packagings often include more libraries or are specialized for a particular application: Installing PythonXY and using IPython Notebook. ProfessorEaston. Enthought Scientific Computing Solutions. Qrcode 4.0.4. Advanced Usage For more control, use the QRCode class.
For example: import qrcode qr = qrcode.QRCode( version=1, error_correction=qrcode.constants.ERROR_CORRECT_L, box_size=10, border=4, ) qr.add_data('Some data') qr.make(fit=True) img = qr.make_image() The version parameter is an integer from 1 to 40 that controls the size of the QR Code (the smallest, version 1, is a 21x21 matrix). Set to None and use the fit parameter when making the code to determine this automatically. The error_correction parameter controls the error correction used for the QR Code.

Running IronPython Scripts from a C# 4.0 Program - Charlie Calvert's Community Blog - Site Home - MSDN Blogs. IronPython is a scripting language hosted on the .NET platform.
This posts shows how you can use the Dynamic Language Runtime (DLR) and the new C# 4.0 dynamic keyword to call an IronPython script from a C# program. Before going any further, it might be helpful to take a moment to explore the architecture that makes this technology possible. How to embed IronPython script support in your existing app in 10 easy steps - Mike Stall's .NET Debugging Blog - Site Home - MSDN Blogs. Previously, I added IronPython scripting support to a real existing application, MDbg (a managed debugger written in C#). In this entry, I'll go through step-by-step how I did that. I'll call specific attention to the goofy issues so that it should be very easy for other end users to get right to the point. I estimate you can modify your existing managed app to have decent IronPython embedded scripting within an hour.I described how this functionality is exposed to the end user in my previous blog entry. If you haven't read that, you may find it useful.
Embedding the Dynamic Language Runtime. This is an introduction to embedding IronPython 2 and the Dynamic Language Runtime in .NET applications. Although the code used through the examples is C#, it is very simple code and is straightforward to adapt to VB.NET. This article started life as a talk given to the Software Development Network in 2008. Embedding IronPython in a C# Application. Download source - 13.96 KB Introduction This article (and the code) demonstrates how to use the IronPython engine inside of a C# Windows Form application. Several different types of interactions (class in C# accessed from Python, class in Python accessed from C#, etc. are demonstrated). Background. Scripting .NET Applications with IronPython. Introduction In this article, I will show an example of how to add IronPython to existing enterprise .NET software systems, and why I think it useful to do so. This isn't a new idea, but hopefully it brings something new to the table.
A 3 minute guide to embedding IronPython in a C# application (secretGeek.net) Agile, blog, [code], editor, html, linguistics, microsoft, productivity, tools, UX Despite knowing absolutely nothing about Python, I've had a lot of fun and a few lttle victories with it tonight. I've built two small apps that I'll include the code for below. I've avoided IronPython up until now, but a terrible problem has arisen lately.
