- 4. INTRODUCTION ď Python is an open source , general purpose programming language that is easy to read . ď It is an interpreted language , which do not need to be compiled to run . ď Python is high level language that will make a programmer focus on what to do instead of how to do . ď Python has been designed to emphasize on code readability with its significant use of whitespace . ď Writing programs in python is less time consuming compared to any other languages .
- 5. ORIGIN SIR GUIDO VAN ROSSUM Python is an interpreted high-level programming language for general- purpose programming .Created by âGUIDO VAN ROSSUM â and first released in 1991. Python has a design philosophy that emphasizes code readability. Notable using significant white space .it provides construct the enable clear programming on both small an large scales .
- 6. FEATURES ď Easy to code ď Free and open source ď Object and oriented language ď Gui programming support ď High-level language ď Extensible feature ď Python is portable language ď Python is integrated language
- 7. INDENTATION Indentation is a very important concept of python because without proper indenting the python code , you will end up seeing INDENTATION ERROR and the code will not get compiled . Python indentation is a way of telling a python interpreter that the group of statements belongs to a particular block of code . A block is a combination of all these statements . Block can be regarded as the grouping of statements for a specific purpose .
- 8. VARIABLES Variables are nothing but reserved memory locations to store values . This means that when you create a variable you reserve some space in memory . Example :- X=5 Y=âjohnâ print(x) print(y)
- 9. OPERATORS Operators are used to perform operations on variables and operators are the main building block of any programming language . Operators allow the programmer to perform different kinds of operations on operand values . Example :- print (10+5) ďą Python divides the operators in the following groups:- ď Arithmetic operators ď Assignment operators ď Comparison operators ď Logical operators ď Identity operators ď Membership operators ď Bitwise operators
- 10. DATATYPES Data types are the classification or categorized of data items . Pythons supports the following built-in data types Following are the standard or built âin data types of python :- ď Numeric ď Sequence type ď Boolean ď Set ď Dictionary
- 11. DECISION MAKING Decision in a program are used when the program has conditional choices to execute a code block . Letâs take an example of traffic lights , where different colors of lights lit up in different situations based on the conditions based on the conditions of the road or any specific rule . ď IF STATEMENT ď IF - ELSE STATEMENT ď NESTED IF STATEMENTS ď IF â ELIF LADDER
- 12. CONTROL FLOW Loops in programming come into use when we need to repeatedly Execute a block of statements . For example : Suppose we want to print âHELLO WORLDâ 10 times . This can be done with the help of loops . The loops in python are :- ď While and while-else loop ď For and for-else loop
- 13. FUNCTIONS ď Functions are generally the block of codes or statements in a program that gives the User the ability to reuse the same code which ultimately saves the excessive use of memory ,acts as a time saver and more importantly . Provides better readability of the Code . ď So basically , a function is a collection of statements that perform some specific task and return the result to the caller . ď A function can also perform some specific task without returning anything .
- 14. OOPS ď Object â oriented programming (OOP) is a method of structuring a program by bundling related properties and behaviors into individual object . Class ď A class is a blueprint for the object . We can think of class as a sketch of a parrot witg labels . It contains all the details about the name , colors , size etc. Object ď An object (instance) is an instantiation of a class . When class is defined , only the description for the object is defined . Therefore , no memory or storage is allocated .
- 15. CONCLUSION At last we want to say that , python is a fully-fledged programming language. Any code you can download the python package index, or anywhere else , can be malicious and would almost certainly go unnoticed by most peopleâs firewalls .
