Introduction to Python

Introduction to Python language

Python is a widely-used all-purpose, high-level programming language. The language began at the end of 1982 when Guido van Rossum entered the team developing the ABC language. 

After the termination of the ABC project, he joined the Amoeba OS team while he worked on a simple project in his free time. Python is the result of the work he performed in his spare time.

The main agenda of this programming language was flexible and general-purpose language. It has been designed by Guido van Rossum in 1991 and developed by Python software system Foundation. It had been principally developed for stress on code readability, and its syntax permits programmers to specific ideas in fewer lines of code.

In the case of the introduction to Python Programming, Python is very simple to use, easy to read, and contains multiple programming diagrams like object-oriented, functional, and parallel programming. Also, it is supported by vast groups that have created a variety of open-source libraries centering on Python.


Python may be a programing language that permits you to work quickly and integrate systems a lot of with efficiency.

Differences between Python and C

Unlike C, Python is a general-purpose programming language. It can be used to build anything from an internet UI to visual applications. 

IPython is a dynamic language. It can manage memory automatically. Python's interpreting level is above C language, so it cannot compete with C in running speed.

However, developing a program using Python may save a lot of time and resources because it is much simple as compared to C.

In Python language, like PHP and Perl, it’s not necessary to define the types of variables. There is no sort of definition in Python while C needs to know variable types.

For example, in C  language, defining an integer variable looks like this:


int a=4;


The above line says that “a” is a variable in memory and the size of an integer. We can just declare a variable without mentioning its type:

a=1


The type of variable is dynamic in Python and it can change during run-time. This code states that “a” is referencing here a part of the memory. The above code is interpreted like this:

1.    A part of memory with the dimensions of an integer is created because Python knows that “1” is an integer.


2.    Python saves the name of “a” into another part of the memory.


3.    A link is created that says “a” is referencing to “1”.


Python can manage memory by itself, unlike C. In Python Programming, every variable has a reference number that states the entire amount referencing it. 


After each declaration, Python increases the reference number. After removing it, it decreases the reference number. After the reference number of a variable, it becomes zero, Python will eliminate the variable from the memory by itself. This technique is called Garbage Collection.

Another difference is that in Python we don’t need to use {} as an indication of a block. Python will interpret blocks according to their indentation.

Features:

1. Python is an Interpreted language
  • There are not any separate compilation and execution steps like C and C++
  • Directly run the program from the Source code file.
  • Python converts the source file into the intermediate type referred to as bytecodes that are then translated into the language of specific pc to run it.
  • No Compilation like linking and loading with libraries, etc.
2. Python is a Platform Independent language
  • Python programs are often developed it can run on multiple platforms.
  • Python is usually used on UNIX, Windows, Macintosh, Solaris, etc 
3. Readable: Python is a readable language.

4. Simple to Learn: Learning python is straight forward as this can be a communicative and high-level artificial language, which suggests it's simple to grasp the language and so simple to be told.

5. Cross-platform: Python is accessible and may run on numerous operative systems like a raincoat, Windows, Linux, Unix, etc. This makes it a cross-platform and moveable language.

6. Open Source: Python is an open-source language. Python has been ported to many platforms. You can use python in Linux, windows, etc.  

7. Massive customary library: Python comes with an outsized customary library that has some handy codes and functions that we are able to use whereas writing code in Python.

8. Supports exception handling: If you're new, you'll marvel what's AN exception? AN exception is an occasion which will occur throughout program exception and may disrupt the traditional flow of the program. Python supports exception handling which suggests we are able to write less error-prone code and may check numerous eventualities which will cause AN exception afterward.

9. Advanced features: Supports generators and list comprehensions.

10. Automatic memory management: Python supports automatic memory management that suggests the memory is cleared and freed mechanically. you are doing not need to hassle clearing the memory.

11. Embeddable: you can embed python with your C and C++ programs.

What You can do with python:

You may be interested in what all areas unit the applications of Python. There area unit numerous applications of Python.

1. Internet development – internet framework like Django and Flask square measure supported Python. they assist you to write server-aspect code that helps you manage information, write backend programming logic, mapping URLs, etc.

2. Machine learning – There are several machine learning applications written in Python. Machine learning could be thanks to writing a logic so a machine will learn and solve a specific drawback on its own. 

As an example, merchandise recommendation in websites like Amazon, Flipkart, eBay, etc. could be a machine learning algorithm rule that recognizes the user’s interest. Face recognition and Voice recognition in the mobile phone is another example of machine learning.

3. Information Analysis – information analysis and knowledge visualization in a similar way of charts can even be developed exploitation Python.

4. Scripting – Scripting is to write tiny programs to automatize straightforward tasks like causing machine-controlled response emails etc. This kind of application can even be written in Python artificial language.

5. Game development – You will develop games in Python.

6. Embeddable: You'll develop Embedded applications in Python.

7. Desktop applications – You will develop desktop applications in Python.
