Goals and Architecture Overview of Python

The main is to provide a compliant, flexible and fast implementation of the Python Language which uses the RPython tool chain to enable new advanced high-level features without having to encode the low-level details. This is called as PyPy.

High Level Goals

Our main motivation to develop the translation framework that provides a full featured, customizable, fast and very compliant Python implementation, working on and interacting with a large variety of platforms and allowing the quick introduction of new advanced language features.

This Python implementation is written in RPython as a relatively simple interpreter, in some respects, it is easier to understand than CPython, that is C reference implementation of Python. Using its high level flexibility to quickly experiment the features or implementation techniques in a traditional approach, require pervasive changes to the source code.

For example, PyPy’s Python interpreter provides a lazily computed object which is a small extension that would require global changes in CPython.

Another example is the garbage collection technique: changing CPython to use a garbage collector not based on reference counting, whereas in PyPy it’s an issue localized in the translation framework which is fully orthogonal to the interpreter source code.

PyPy Python Interpreter

PyPy’s Python Interpreter is written in RPython that implements the full Python language. This interpreter very closely emulates the behavior of CPython and contains the following key components:

Bytecode Compiler - This is responsible for producing the Python code objects from the source code of a user application. The bytecode compiler is the preprocessing phase which produces a compact bytecode format via a chain of flexible passes (tokenizer, lexer, parser, abstract syntax tree builder, bytecode generator).

Bytecode Evaluator – It’s responsible for interpreting the Python code objects. The bytecode evaluator interprets this bytecode. It does most of its work by delegating all actual manipulations of user objects to the object space. The latter can be thought of as the library of built-in types. It defines the implementation of the user objects, like integers and lists, as well as the operations between them, like addition or truth-value-testing.

Standard Object Space – This is responsible for creating and manipulating the Python objects that are seen by the application. The division between bytecode evaluator and object space gives a lot of flexibility. One can plug in different object spaces to get different or enriched behaviour of the Python object.

Exceptions in Python

What is an Exception?

An Exception is an event or error that would happen during the execution of a program that would disturbs their execution. Whenever there is an error, Python generates an exception that could be handled. It basically prevents the program from getting crashed. When a Python script raises an exception, it must either handle the exception immediately otherwise it terminates and quits.

Why we use Exceptions

There was a valid as well as invalid exceptions occurred many times. Exceptions are convenient in many ways for handling errors and also the special conditions in a program. If we have some set of code which produces error, at that time we can use exception handling technique.

Handling an exception

If you have some suspicious code that may raise an exception, you can defend your program by placing the suspicious code in a try: block. After the try: block, include a except: statement, followed by a block of code that handles the problem as elegantly as possible.

Why Learn Python?

Python is the great language for beginners which are easy to learn and maintain. To start programming in python, it’s easy to complete a program within two days. By using other languages it is extremely vast because in that go into its packages, like its machine learning packages, SciPy packages, Matplotlib and so on. So, it might take more time to complete.

• Python’s biggest strength is that its bulk of library is portable.
• There are millions of people around the world are working on Python and making contributions to its development.
• It’s an open-source language. If you have Python in your system means write your own piece of package and then submit it for approval.
• There are hundreds and thousands of packages available that are portable and helps in programming to clarify some of the stuff.

PyCharm

It is a GUI-based development environment having the Python packages connected to Python. For example, everyone has Twitter and Facebook accounts. How do analyze date from Twitter and Facebook? PyCharm package is used to

• pull streaming data from Twitter or Facebook,
• save it and conduct a search in it,
• do a sentiment analysis, or
• Run some kind of machine learning algorithm on it.

Many people worked hard in order to create these packages. Accordingly, all you have to do is read a little bit of documentation about this package and start implementing, instead of writing thousands of lines of code. Even in Python, you may end up it by writing 50-60 lines of code.

Machine Learning

Machine learning algorithms are mostly used to create artificial intelligence in machines which are also available in SciKit Learn. It has been optimized in a way that the machine learning code would write in just 4-5 lines. Use this package, invoke those procedures and functions, pass the data, fit your model and then predict the outcome which is very easy. Python has made lot of things easier and it is still being contributed by thousands of developers across the world. It’s going to get much better and that is why it’s becoming popular.

Data Analytics

With libraries like PyDoop and SciPy, it’s a dream come true for Big Data Analytics. Nowadays, there are tons of data flowing from everywhere, those would be analyzed first. In some organizations, they have the data from the past 70 years, while in others they have data from past 30-40 years and it’s too huge. They would store this data in some database somewhere, and it might be lost. Let’s take data of 1970s; but who cares about the 1970s data in this age? However, to find a trend, those data’s are important in a way. It’s not just important, it’s necessary to find a trend.

For example, I am in a computer manufacturing company and I want to find a trend as to what’s happening. You might have heard about forecasting and how people do that. Basically, they capture the data of the past 2-3 years. Let’s say, last year in March, the sales were 1 million, in April the number was 2 million, in May 3 million, and so on and so forth. They would just take this data and then extrapolate it to this year. Then, they assume that since last year in August, it was 1 million, this year too in August, it might be 1 million. That’s how they extrapolate it. So just look at the amount of data taken. May be in a couple of years when they average out the data of those years, they may do a moving average or use some kind of statistical algorithm but with a limited amount of data.

With the advent of Hadoop and Big Data, Data Processing has changed. Nowadays, we can process the data for 30 years and find a pattern, which might be anything. It should be sin wave or cosine wave to some graph, which is not any kind of wave, but just a zigzag graph which tell the pattern. In order to implement those algorithms with so much of data with the help of libraries like, PyDoop and SciPy.

Growing Interest in Python

Last 30 years the python has been there, but the growth of interest started in July, 2010. The name python is originated from the play in London (UK) doesn’t derive from the animal python (snake). In July 2010 the interest of Python started growing well to today itself. Most of the organizations, particularly the one dealing with data and Data Analytics asking the experienced and also having knowledgeable person in python.

Range Functions and Sequences in Python

Range Function

Range() generates lists containing arithmetic progression.

Three variations of range() function

>> range(stop) – Starts from 0 till (stop – 1)

>> range(start,stop) – Ends at (stop – 1)

>> range(start,stop,step) – Step cannot be 0, default is 1

Example of Range Function

range(stop) - If the range is defined as 5, it would simply show the list of numbers falling in the range from 0 to 5. The default range starts from 0 and stops before 5, as defined.

range(start, stop) – The point of starting as well as stopping is defined in this. As shown in the example below, the start range has been defined as 5, while stop range as 10. Hence, it would display the numbers 5, 6, 7, 8, 9, which range between 5 to 10.

range(start, stop, step) - The first two values defined here are the same, start and stop, while the third one is step, which means the difference between every two consecutive numbers. For example, if range is defined in this way: range(0, 10, 2). It will give away numbers between 0 to 10, but with a difference of 2, in this way: [0, 2, 4, 6, 8]. The step here cannot be given 0 value. It has to be 1 or greater than 1.

Sequences in Python

A sequence is the succession of values bound together by a container that reflects their type. Almost every stream that we put in Python is a sequence.

Types of Sequences

• Lists
• Tuples
• Xrange
• String

The python is supported by some other sequences are strings, lists, tuples and Xrange objects. Python has a bevy of methods and formatting operations that can perform.

List

• A list is a sort of container which holds the number of other objects, in a given order.
• The list type implements the sequence protocol which allows adding and removing objects from the sequence.
• It is an ordered set of elements enclosed in square brackets.

Simple definition of list – li = []

li = list() # empty list

li = list(sequence)

li = list(expression for variable in sequence)

‘example’

            >>> list(a)

            [‘e’, ‘x’, ‘a’, ‘m’, ‘p’, ‘l’, ‘e’]

            >>> list3 = [‘Hadoop’, ‘Python’, ‘Data Science’, ‘Pig’, ‘hive’]

            >>> list3

            [‘Hadoop’, ‘Python’, ‘Data Science’, ‘Pig’, ‘hive’]

            >>> list3[2:]

            [‘Data Science’, ‘Pig’, ‘hive’]

            >>> list3[2:3]

            [‘Data Science’]

            >>> list3[2:4]

            [‘Data Science’, ‘Pig’]

            >>> list3[2:5]

            [‘Data Science’, ‘Pig’, ‘hive’]

            >>>

Accessing List Elements

To access the elements of a list:

n = len(li)

item = li[index] #Indexing

slice = li[start:stop] #Slicing

List Indexing

list[i] returns the value at index i, where i is an integer. A negative index accesses elements from the end of the list counting backwards. The last element of any non-empty list is always li[-1]. Python raises an IndexError exception, if the index is outside the list.

Accessing Command Line Arguments

Python supports the creation of programs that would run on the command line, completely with command-line arguments. It provides getopt modules that parse the command line options and arguments. The Python sys module provides access to any of the command-line arguments via sys.argv. It solves two purposes:

• sys.argv is the list of command line arguments
• len(sys.argv) is the number of command line arguments that are in the command line
• sys.argv[0] is the program, i.e. script name

Executing Python

The python should be executed in the following
$python Commands.py inp1, inp2 inp3

Example

import sys
print ‘Number of arguments:’, len (sys.argv), ‘arguments.’
print ‘Argument List:’, str(sys.argv)
It will produce the following output:
Number of arguments: 4 arguments.
Argument List: [‘sample.py’, ‘inp1’, ‘inp2’, ‘inp3’]
