Print Prime Number Program in Python

Prime number is only divisible by 1 and number it self. So for this type of program you need to check number is divisible by other number or not. If number is divisible by others number it means number is not prime number.

Prime Number Program in Python

# Receive input from the user
num = int(input("Enter a number: "))

# prime numbers are greater than 1
if num > 1:
   # check for factors
   for i in range(2,num):
       if (num % i) == 0:
           print(num,"is not a prime number")
           print(i,"times",num//i,"is",num)
           break
   else:
       print(num,"is a prime number")
       
# if input number is less than
# or equal to 1, it is not prime
else:
   print(num,"is not a prime number")

Output

	
Enter a number: 407
407 is not a prime number
11 times 37 is 407

Introduction of SQL

Introduction of SQL SQL (Structure Query Language)  was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system. Features of SQL SQL is not a case sensitive language. Every commands in SQL should ends with semicolon(;). SQL can also called as sequel (SEQUEL). SQL Sub Language SQL is mainly divided into four sub language Data Definition Language(DDL) Data Manipulation Language(DML) Transaction Control Language(TCL) Data Control Language(DCL) Only for remember You can remember all these command like below; DDL Commands "dr. cat" d-Drop, r-Rename, c-Create, a-Alter, t-Truncate. DML commands "sudi". s-Select, u-Update, d-Delete, i-Insert.

SQL Syntax

SQL Syntax SQL follows some unique set of rules and guidelines called  Syntax . Some basic guidelines related to SQL Syntax are given below; SQL is not case sensitive. Commonly SQL keywords are written in uppercase. You can write SQL statements in one line or in multiple lines. SQL are depends on relational algebra and tuple are relational calculus. SQL statement SQL statements are started with any of the SQL commands/keywords like SELECT, INSERT, UPDATE, DELETE, ALTER, DROP etc. and the statement ends with a semicolon (;). Syntax SELECT * FROM table_name; Why use semicolon after SQL statements ? Semicolon is used to separate SQL statements. It is a standard way to separate SQL statements in a database system in which more than one SQL statements are used in the same call. Some Basic Commands SELECT:  It is used for Retrive data from a database. UPDATE:  It is used for updates data in database. DELETE:  It is used for deletes data from da...

DDL Commands in SQL

DDL Commands in SQL Data Definition Language(DML)  statements are used to define data structures in database. DDL Commands All DDL command are given below; Drop Create Alter Rename Truncate All DML Command I will discuss in detail later.
