Its special features and third-party tools can be upgraded depending on what is required. However, recent times have brought rise to more advanced programming languages that are more complex and can offer more but it still makes it among the top.

What is python programming?

Python is a unique high-level, interactive, interpreted and object-oriented and scripting language. Python language is more of English language whereas others consider the use of punctuation. It uses simple and understandable syntax that is best for beginners. It is easy to learn and they have resources that help you with all the information you need to create a perfect code.  It is easily applicable and can easily be used in different sectors at workplaces and working on projects. It does not have long and cumbersome instructions or complexity. It is easy to learn and it flows easily.

For it to work more easily and effectively, it comes with a number of great features which makes it the best. You can definitely get everything you need with python.

 A beginner language – python is a friendlier language that uses simple commands and codes that support the development of several applications from a simple word or text to complex ones. It helps you develop programs to give you the most simple and easy learning.

 Interactive – python allows you interact with the interpreter directly on writing programs.

 Interpreted – you can execute your programs at runtime. You do not necessarily need to compile them before completion. Python interprets your instructions with ease. You do not necessarily have to compile your data into binary. You directly run your programs directly from the source.

 Object-oriented – you are allowed to use codes within objects. It uses the object-oriented skills and techniques to create a program that is simple and worthwhile.

High range of libraries – using the library, you can do several things such as documentation generation, threading, databases, expressions, web browsers, cryptography, Graphical User Interfaces and any other tasks which depend on the system. You can have all the knowledge on simple and complex matters.

Extensible – in case you are looking for a code to run fast or do not want to open algorithms, you can easily code that art of the program using the C AND C++ on your python project.

Portable – it has been designed t work on a number of platforms such as windows, Linux and Macintosh, Solaris, play station, Amiga, VxWorks and so on. All your python programs can work without any need of changes.

High level language– as python is a high quality language, you do not have to worry about any small details such as memory loss or managing the entire memory as it comes with in-built features which handles all your programs effectively.

Easy to learn– as it comes with the simple syntax and strict English language, you do not have to worry about the pseudo language rather than finding solutions to problems within the program. It is easy to start and understand.

Embeddable– you can easily embed your programs such as C to give you the scripting abilities for the users of your programs.

History of python programming

Guido Van Rossum created python programming language in late 1980s which was to replace ABC language which was outdated and inspired by SETL. Through his hard work, effort and consistency, it greatly advanced and it was implemented successfully. Python language capabilities are inspired by C++, C, UNIX shell, Algol-68, modula-3, ABC and other scripting languages. As much as Guido later stepped down as the developer and creator of the software, its development team and unit still handles all the operations.

From time to time, python has released software with great features that makes it more powerful and worth using. For instance, in 2000, saw the release of 2.0 that came with great support system for unicode and garbage collector, python 3.0 which were to support 2.6 and 2.7 versions. It has over time developed new versions of python that makes it still preferable.

It allows you to handle the complexity of software applications and creating all types of applications; small or large.

 What makes up python programming?

Python programming comes with a wide range of components that works together to make the programs effective. Depending on the service you need, it can handle almost every task both simple and complex.

To understand more of what the python contains and refers to, let’s have a look at them:

The Zen of Python

This represents the summary of the central philosophy of any computer or software programming language. It is made up of strict principles that can help in coming up with programs that make the decisions on how the python programs can be designed and used.

 These are some of the principles found in the Zen of Python:

  • The flat is better than the nested
  • Explicit is better than implicit
  • Beautiful is better than ugly
  • The complex is better than complicated
  • Although that way may not be obvious at first unless you are a Dutch
  • Sparse is better than dense
  • The flat is better than nested
  • Readability counts
  • Unless explicitly silenced
  • In the face of ambiguity refuse the temptation guess
  • Now is better than never
  • Errors should never pass silently
  • Although never is often better than right now.

Python programming was uniquely created with all the central storage for all its functions. It is quite effective as you are allowed to add programs, texts and values t already existing applications. It was originally created to handle changes and make adjustments from the original ABC programming technique that had a lot of issues.

With Python programming, you will find it simple creating less complex or complicated grammar and syntax that give developers options on coding methods depending on their needs. Basing on Zen’s Python principles, there needs to be ways and preferably only one obvious way to handle issues that Python bases its philosophy ideology. A developer from Python Software Foundation wrote a book that “describing something as clever was not received positively by the Python culture.”

The main reason for Python developers is to create a program that is simple and easy to understand as well as fun by those accessing it. The language’s name is a representation of its fun side. The name is a tribute to a particular British comedian known as Monty Python. It is an amazing feature for the program to experience the skills and techniques applied in referencing materials and tutorials. This ensures users quickly grasp how it works and its use in computer programming.

The term pythonic is a common name in the python programming. It refers to when a code or language is compiled on python’s philosophy and its users are able to read and understand. Those who greatly admire python are referred to as pythoneers, Pythonistas, and pythonists.

Python Syntax and Semantics

The python syntax refers to the set rules that determine how the python programs will be written and interpreted. It has easy to follow rules that make it differ from other programs. In most cases, it includes English keywords that are easily understandable and simple to read. This is unlike other languages which include punctuations which might be problematic. Some of these words include return, def, yield, finally, import, right, except, while and much more.

Indentation

Python incorporates the use of whitespace in indentation to limit locks in the statements. An increase in indentation occurs after several statements. A decrease means the semantic structure is accurately visually represented.

PYTHON DATA TYPES

Python comes with several types of data types that help in identifying the correct variable. Python has a number of built-in data types that helps it function effectively. For instance:

Numeric

This is a data type that mostly represents numeric values. It is made up of four data types which include float which deals with numerical data that is floating and can be represented by fifteen decimal places, int which is a form of numeric value representing integers that are of unlimited length, long which means the integers are long like any other plain integer and complex which symbolizes the complex numeric number, values, and figures.

Python Boolean

Python Boolean is a type of data that holds only two numerical values. The two values represent true or false which is either logic or Boolean algebra. In most cases, the two values in Boolean algebra are constant. Depending on how the Boolean affects or describes a situation, the conditional statements are linked to actions on how the developer decides. Here, the value to be represented by logic does not necessarily have to be Boolean.

Python List

This is a form of a container or collective type of data where all the structures and components of different types of data are stored consecutively. It has the ability to store a large number of data in a particular order of number. The data in a list is always in a sequence that is well organized to meet all the rules and regulations with zero always being at the top of the page. You can literally fill any kind of data in a list for easy access and proper storage.  It ensures your data is preserved effectively and organized in a correct and accurate way for future reference and so on.

Python Strings

This is an arrangement and organization of elements in the form of symbols. For example, computers mainly deal with binary and numbers and exclude characters. In relation to computers, data is stored in the form of 0’s and 1s.  To be able to convert a figure or value into a number, it has to go through the process known as encoding and decoding. Encoding is in most cases used in the conversion process.

Python tuple

These are objects or tools that are split/separated using commas.  It is mostly immutable and it uses parentheses. It is impossible to make any changes to the contents of the tuple. It is easier to divide the elements that are separated by commas and parentheses in a python tuple written as ( ). When you need to write a value inside a tuple, you have to add a comma. 0 is one of the first indexes in the tuple.

If you need to access the data in tuples, square rackets are mostly preferred in slicing the index. However, it may be tricky changing or making adjustments in content in the tuple due to their immutable nature. If you need to change the contents, the only option you have is creating a new one using the existing content. Deleting the existing content in the tuple may prove hard unless you are willing to delete the entire tuple using the Del keyword.

Python Set

Python set is a form of data type that does not have a particular order. It is impossible for you to make any changes leave alone coming up with a duplicate list or element. It only contains a unique set of values that cannot be duplicated. You can easily remove or add content to the python set. For mathematics operations, the symmetric difference can be handled using the python set.

Python programming is an interesting language that is not only easy and simple to learn but comes with a wide range of benefits such as great salary, a wide range of library and so on. It is an advanced form of language but does not reach the standards of the new and more advanced programming languages around. It is more effective and still remains the best with several data types that make it work effectively but may not handle the most complicated projects.

Learning the python basics may save you a lot if you need to preserve your data, make changes or protect it. It is worth the try.
