What is Python Programming - Python Tutorial




What is Python ?

  • Python is a famous general-reason programming language that may be used for an extensive kind of applications.
  • It consists of high-degree information structures, dynamic typing, dynamic binding, and lots of greater functions that make it as beneficial for complicated application development as it's far for scripting or "glue code" that connects components together.
  • It also can be extended to make system calls to nearly all operating system and to run code written in C or C++.
  • Due to its ability to run on almost each system architecture, Python is a universal language observed in a whole lot of specific applications.

Characteristics of Python

  • It helps functional and structured programming strategies as well as OOP .
  • It may be used as a scripting language or may be compiled to byte-code for building huge applications.
  • It gives very high-level dynamic data types and helps dynamic type checking.
  • It helps automated garbage collection.
  • It may be easily included with C, C++, COM, ActiveX, CORBA, and Java.

How Python is used

  • Data sciences
    • This field makes up a sizable user base of Python for both its computing and compiling of data libraries.
  • Machine learning
    • Python's code can implement machine learning, which helps refine algorithm-based tech from voice recognition to content recommendation.
  • Data mining
    • Python's scalability also makes it an attractive program to process and mine big data, which has seen a lot of mileage in the finance sector.

Advantages of Python

  • Popularity and Access
    • Python have a huge community to support it, which helps maintain its accessibility to any skill level - it's also free and open-source software.
  • Simple Syntax
    • The Python coding language has an easy-to-learn syntax and uses English words.
  • Readability
    • Lines of code written in Python are also easy to read.
    • For example, Python uses a nice, clean break in the form of a new line of code to complete a command, rather than semicolons or parentheses.
  • Scalability
    • You can start a program in Python without having to worry about the hard task of rewriting or adapting code for other platforms as you scale up.

Disadvantages of Python

  • Speed
    • Python is an interpreted language and is slow as compared to C/C++ or Java.
  • Simple Syntax
    • The Python coding language has an easy-to-learn syntax and uses English words.
    • Unlike C or C++, it’s not closer to hardware because Python is a high-level language.
    • As we all know that compilation and execution help to work normally, but in this case, execution of Python takes place with the help of an interpreter instead of the compiler as we have seen that Python code is executed line by line, which causes it to slow down.

  • Mobile Development
    • However, Python is strong in desktop and server platforms, that is it is an excellent server-side language but for mobile development, Python is not a very good language which means it is a weak language for mobile development.
  • Memory Consumption
    • For any memory intensive tasks Python is not a good choice. That is why it is not used for that purpose.
    • Python’s memory consumption is also high, due to the flexibility of the data types.
  • Database Access
    • Python is a robust programming language with minimal stress and worries. But, this language is highly insecure and can be used only at one’s own risk. There are some limitations of Python with database access.
  • Runtime Errors
    • One of the major drawbacks of this language is that its design has numerous issues.
    • Python programmers face several issues regarding the design of the language.
  • Difficulty in Using Other Languages
    • The Python followers become so familiar to its features and its extensive libraries that they face problem in learning or working on other programming languages.
  • Simplicity
    • Python is a simple programming language which is also the biggest disadvantage. It can indeed be a problem.
    • Its syntax is very simple which makes a programmer more of python person and because of which they might feel code of harder language like Java unnecessary.
