What is Programming | Programming Language | Compiler | Why Python

Hello Coders,


 Here we are with new series of python.


                                    Programming

  • Programming is a art to convert a idea into set of instruction(program) a Computer can follow.
  • Person converting idea into set of instruction is called Programmer.
  • Medium of giving instruction is known as Programming language.

                                     

                           Programming Language

Programming Language is a method by which a coder give set of instruction to computer to perform a specific task or make a Software.


There are two types of programming language
  • Low level programming language
  • High Level programming language

                                  Low Level Language

  1. These Language are closer to Computer's native language 0's and 1's.
  2. They don't need any medium (compiler or interpreter) to convert code into machine language that's why their processing is fast.
  3. They uses less memory and are more effective but they are complex to write.
  4. Assembly and machine code are low level Language.

                                     High Level language

  1. They have large difference To Computer's native language.
  2. They need a compiler or interpreter to get converted into machine language hence they are comparatively slower.
  3. They uses large memory and are less effective but they are easy to write.
  4. Java and Python are high level language. 
     

Compiler -- They are special kind of program which convert source language written in high level language into machine language which is understood by computer's.


                                   Why Python

We have many programming language but why should we learn python. We should be precise while choosing programming language.


  • Python is general language or we can it's English like language most of its syntax matches to language so it's syntax is easy to learn.
  • By learning Python we can access a wide range of development field be it be Machine Learning,Artificial Intelligence,Web development,Data scientist all you can do with python.
  • It has amazing library.Due to its libraries you can do most of work by just calling a function.It's library helps to write code easily.

Hello coders, Today we will learn to print Hello world,How to use comments in python ,Escape character,How to live a line,\n,\t,\r,Finally we will go through some practical question. Printing in Python print("hello world") Run an Online python compiler Here  and test it. Not only hello world but you can print any text in python console use print keyword. print("any text here") Printing Hello World In Python Comments in Python | why we need comments   Suppose you are writing  a Python program which is very vast.You can't remember why you have used that piece of code.Here comes the use of comment. Or suppose you have to present this code to a non technical person then you can use comments to specify why you have written that piece of code. Comments are not executed by compiler. ''' your comments go here''' Use of comment --- '' Below code is used to print hello world''...

Variables in Python | Data Types | Rules For declaring variable |Storing and Printing the value of variable | Operation in variable

What are variable As the name suggest a variable is entity whose value can be changed any time you want. In other programming language like C,C++,Java we have a special command to declare variable.In these language we also have to mention the type of value variable is storing whether its Integer,characters or decimal. But don't worry its python you don't need any command to declare a variable.Its declared when you first equate the value to a variable. X = 5              (X is treated as integer) Y = "Hello"    (Y is treated as string due to " ") Z = 5.6            (Z is treated as decimal) Datatype Data type refer to the type of value a variable is storing There are basically three type of datatype Integer --- These contains integral Data 5,4,47,100.We can     apply mathematical operation to these String  ---- These datatype contains words characters any...
