Python

Article by Prabhakar Published on


python is basic language if you are new to programming  then better to start with python. Already we have discussed what is programming  and tips to start/learn programming  in one of my previous post. And python is fastest growing language in terms of developers and companies using it. Python can be used to make Web applications, Game development, machine learning, Data science etc.
       So in this Techy Drift platform we will learn python. This tutorial is for Absolute beginners only who are new to programming. Here we will cover Syntax,concepts,and basics. I will show the programs execution through my own videos. So  guys let's get into the topic.

PYTHON:-

It is a Programming Language also an interpreted, Object oriented and High-Level Language. As we know that using python we can make wonders. Do you know why python is most important and famous ?? We  already  have c, c++, java etc but still python is very famous. some people   say python is a new language but the fact is java came in 1995 where areas python is  1989. It is easier than all languages like c, c++, java etc.Even in some colleges they are teaching python as a basic language.There are some companies which are using python for some features like Google,YouTube etc.  

Getting Started With Python:-

Go and check in YouTube we have many videos for installing Python and python IDLE . The stuff explained below will only work in python IDLE not in IDE's because to run in IDE we have a special rules for that.

  1. To add values use this operator "+".
  2. To subtract use "-"
  3. For multiplication use " * "
  4. For division use " / ", here you will get float type value i.e. decimals to get integer type value use "//".
  5. To get power values use " ** " i.e. 2**2 is read as 2 square i.e. 4,  2**3 is read as 2 power 3 i.e. 8 ,  3**2 is read as 3 square i.e. 9  .
  6. As we know this is for division ' / '   and to get remainder we will use    " % "
  7. To write a strings we need to use single or double quotes Ex:-'prabha' or "prabha".
  8. No need to use semicolons at the end of the statements.
  9. For writing the string follow the video carefully.
  10. Use" print() "  to print statements.
  11. We need to use "  \ " in between prabha and 's to avoid errors because the quotes should be balanced in the statement Ex:-print('prabha\'s "computer"').
  12. To get a string two times use " + "  Ex:-'prabha'+'prabha'.
  13. To get a more than 2 times we have a separate trick i.e. use ' * ' with a number(here the number is how many times you want) before string. Ex:- 5*'bat'. the bat will print 5 times.
  14. At the end we used slash n(" \n ") actually it is for printing the string after the ' \n ' in new line but to avoid it we need to use " r " in the statement. 
     Ex:-print('c:\docs\nitin') ==>It is going to print 'c:\docs' in one line and 'itin' in another line to avoid it we will use ' r ' Ex:-print(r'c:\docs\nitin') ===> it is going to print 'c:\docs\nitin' in single line.
            

                                                                                                                                          
  If  any doubts and  suggestions  regarding the above topic, Use the below comment section .In the next session we will continue  with variables in python.

Types of Operating System

Article by Prabhakar Published on
 Types of Operating System Batch Operating system Time sharing Operating system Distributed Operating system Network Operating system Real Time Operating system Multi programming/Processing/Tasking Operating system Mobile Operating System Batch Operating System               In a Batch operating system the similar jobs are grouped together into batches with the help of some operators and these batches are executed one by one. For example, suppose we have ten programs, some are written in c++ programming language, Some are written in c programming language and the rest are written java programming language. Now, every time we run these programs one by one, we have to load the compiler of that particular language and then run the code. But if we do a batch of these ten programs, The advantage with this approach is that for the c++ batch, you only need to load the compiler once. Similarly, for Java and C , the compiler only needs to load once an...

Python Variables

Article by Prabhakar Published on
variables,the name itself implies that a variable is something which can change.  Variables are like containers for storing  our data values in memory. we can change the data in variables, in python everything is an object and variables are like names given to the object, by labeling them we can easily access them. In other high level languages like C programming language, c++ programming language, and java programming language. etc.,   we need to declare the datatype of the variable , but in python it will automatically recognize the type of data you are storing in a variable. ** Remember that a variable is a name which is given to a value not to the memory. Declaring a variable is very easy you need to assign a value or a string using '=' operator. >>> p=9 >>> print(p) 9 Assigning a single value to multiple variables We can assign a single value to multiple variables.  >>> a=b=c=56 >>> a 56 >>> b 56 >>> c 5...

Even or Odd Number and Factorial of a Number in Python Programming

Article by Prabhakar Published on
1. To Check if the given number is even or odd If a number is completely divided by 2 then it is even number. When the number is divided by 2, we use the remainder operator %  to calculate the remainder. If the remainder is not zero, the number is odd. SOURCE CODE:- n= int ( input ( "enter any number:- " )) if (n% 2 == 0 ): print (n , 'is even number' ) else : print (n , 'is odd number' ) OUTPUT 1st Run enter any number:- 2 2 is even number 2nd Run enter any number:- 3 3 is odd number In the above code we use "Simple if" statement.  In the above program, we ask the user for input and check if the number is odd or even. 2.Factorial number Factorial of a number defined as the product of all numbers from 1 to given number. For example  5!(5 factorial)=5*4*3*2*1 is 120. Note = factorial of 0 is 1 SOURCE CODE n= int ( input ( "Enter any number:- " )) fact= 1 for i in range ( 1 , n+ 1 ): fact=fact*i print ( 'factorial of' , ...

DATA TYPES IN PYTHON | (Numeric,Boolean, Dictionary)

Article by Prabhakar Published on
Previous Variables in Python  In python programming language everything is an object and data type tells us which types of value the object is. Data types are classified into five types in Python programming language, they are:- Best Laptop for Web Development  in 2021. NUMERIC DATATYPES BOOLEAN DATATYPES DICTIONARY SEQUENCE DATATYPE SET type() method  Type method is used to know what type of data we are using. Numeric Data Types Numeric type consists of numerical value data types for example whenever we assign a decimal value or numbers to variables then it comes under numeric data types. It contains : int float complex type Int or Integer It is a data type where the value given by the user can be positive or negative and can be of any length that means it can be a big integer or small integer but it should not be a fraction or a decimal value. #Python Program to # demonstrate int value p= 5556677 print ( type (p)) q=- 45 print ( type (q)) #output < class 'int' >...

Computer System Architecture

Article by Prabhakar Published on
 Based on number of general purpose processors computer systems are classified into three types.They are: Single Processor Systems. Multiprocessor Systems. Clustered Systems. Single Processor Systems From the name it is very clear that it has only single processor. A major central processing unit that can execute a set of general utility instructions, including user process instructions. There are some other special purpose processors present that performs device specific task. In the single processor system apart from the main central processing unit(CPU) there are also other processors which are present which does not do the general purpose task but it performs some device specific task. It means that we have a certain devices in our computers like keyboard, disk, etc. for all this they may be some microprocessor  which is specified to do a specific task related to that device like for example keyboard, when we press a key on our keyboard the keystroke has to be converted to...
