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' >...

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' , ...

  INDENTATION : Indentation is nothing but giving proper spaces they are like {} braces don’t need to mention any {} braces to indicate a set of code or code so our compiler or interpreter need to understand from where to stop and where to continue again .our compilers or interpreters don’t know the order in which the statements of the code should be executed so we use indentations to specify compilers to execute them in order ** we all know that python is very easy and a simple language which means we don’t need to mention datatypes and syntaxes also will be very easy to understand when   compared to other languages but if you don’t give proper indentation   then it shows us hell, so we need to use proper indentation or else you will be ending up seeing that that “INDENTATION ERROR”   message . Ø   Actually, indentation is nothing but giving spaces before the statements Ø   Actually, we use tab or space for indentation in python, by default python us...
