Python is a widely used high-level, general-purpose, interpreted, dynamic programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C++ or Java. The language provides constructs intended to enable clear programs on both a small and large scale.
Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles. It features a dynamic type system and automatic memory management and has a large and comprehensive standard library. (Source)
Pythpn has seen great popularity in the programming world lately. For this reason, we have gathered 10 awesome Pythpn tutorials to ease you into the framework and help you boost your own Web Development projects! Let’s kick it!
1. Python CSV Reader / Writer Example
Python has native support for CSV readers, and it’s configurable (which, as we’ve seen, is necessary). There is a module csv which holds everything you need to make a CSV reader/writer, and it follows RFC standards (unless your configuration overrides them), so by default it should read and write valid CSV files.

2. Python Decorator Tutorial
Sometimes, we encounter problems that require us to extend the behavior of a function, but we don’t want to change its implementation. Some of those problems could be: logging spent time, caching, validating parameters, etc. All these solutions are often needed in more than one function: you often need to log the spent time of every http connection; you often need to cache more than one data base entity; you often need validation in more than one function. Today we will solve these 3 mentioned problems with Python decorators.

3. Python Threading / Concurrency Example
Threads are processes which run in parallel to other threads. In a utopian scenario, if you split a big process in 2 threads, these threads will run in parallel so it would take half the time. This is not true in most cases. Using CPython, there is a mutex that prevents multiple native threads from executing Python byte codes at once. It’s called GIL (global interpreter lock).

4. Python Logging Example
Logging is a process through which an application pushes strings to a handler. That string should be a line containing information about the piece of code from which it was sent and the context in that moment. It is a feature every application must have, and it’s as important as any other functionality you add to the application in question. It is the easiest way to know what your application is doing, how, how long does it take, etc.

5. Python Django Tutorial
Django is an open source web framework which solves most common problems of a web application development. It has some very useful features like an auto generated admin page and an ORM. It’s a high-level framework, so we just need to focus on the actual core logic of our business and let Django take care of mappings, filters and such. It works by defining some standards that, if you follow them, will make the application’s development so much easier and faster.

6. Python Dictionary Example
Dictionaries in Python are data structures that optimize element lookups by associating keys to values. You could say that dictionaries are arrays of (key, value) pairs. Their syntax is pretty familiar to us, web developers, since its exactly the same as JSON’s. An object starts and ends in curly braces, each pair is separated by a comma, and the (key, value) pairs are associated through a colon (:).

7. Python Sockets Example
In this tutorial, we’ll talk about INET, STREAM sockets. We’ll talk about what sockets are, and learn how to work with blocking and non-blocking sockets. First things first, we’ll make a distinction between a “client” socket (endpoint of a conversation), and a “server” socket (switchboard operator). Your client (e.g. your browser) uses only client sockets, and your server uses both client and server sockets.

8. Python Map Example
In this tutorial, by using python 3.4, we’ll talk about map functions. Strictly speaking, a map function, is a function that accepts a function and an array as arguments, and applies the given function to each element of the array, returning another array with the result of each transformation.

9. Python Subprocess Example
In this article, using Python 3.4, we’ll learn about Python’s subprocess module, which provides a high-level interface to interact with external commands. This module is intended to be a replacement to the old os.system and such modules. It provides all of the functionality of the other modules and functions it replaces.

10. Python Send Email Example
In this example, by using Python 3.4, we’ll learn how to send mails using Python’s smtplib module. SMTP stands for Simple Mail Transfer Protocol. It’s a protocol which handles sending e-mails and routing them between mail servers. To send a mail, we need the host and port of a server, then we send to this server the message with a sender and a list of receivers.

Nice list! It will be helpful to many devs for sure. Also, I’d like to suggest adding http://python.libhunt.com/ as it might be useful as well.
Hello,
Thanks for sharing these nice tutorials.
