Python Tutorials
Python is Programming language:
- Programming language is a pre-defined application.
- Programming languages are used to develop applications.
- We use applications as a medium for communication.
- Communication is the process of data sharing.
- Different types of applications can be developed using Python language.
Way of Communication with machine:
- Machine understands binary code.
- We cannot define machine instructions directly to input.
- We use high level languages to define source code.
- Source code need to convert (interpret) before input to machine.
- Interpreter is a program that converts the source code into machine code
Types of Languages
Low Level Languages:
- A low level languages are near to computer hardware and consist of binary(0’s & 1’s) or Mnemonic codes(MUL,ADD) but far from human languages
- Low level language does not need a compiler or interpreter to run the program, a processor can run low level code directly.
- Technically Low-level Language classified into two types-
- Machine language
- Assembly language
Machine Language:
- The name machine itself implies that ,programming is done at the machine level which means machine language are the only way to communicate directly with computers.
- It’s a language which is directly understood by the computer.
- In Machine Language we write only binary, octal or hexadecimal code.
Assembly Language:
- Assembly languages have the same structure and set of commands as machine language, but the difference is they enable a programmer to use names instead of numbers.
- By using assembler ,we can easily convert assembly code to machine code
- Assembler is a program that takes computer instructions and converts into a pattern of bits so that the computer’s processors can use it to perform basic operations.
High Level Language: High level language is a programming language that enables a programmer to write programs that are independent of a particular type of computer, such types of language are called as high level because they are closer to human languages and further from machine language.
