Python program to check whether a number is Prime or not

Prime numbers:

A prime number is a natural number greater than 1 and having no positive divisor other than 1 and itself.

For example: 3, 7, 11 etc are prime numbers.

Composite number:

Other natural numbers that are not prime numbers are called composite numbers.

For example: 4, 6, 9 etc. are composite numbers.

See this example:

  1. num = int(input(“Enter a number: “))  
  3. if num > 1:  
  4.    for i in range(2,num):  
  5.        if (num % i) == 0:  
  6.            print(num,”is not a prime number”)  
  7.            print(i,”times”,num//i,”is”,num)  
  8.            break  
  9.    else:  
  10.        print(num,”is a prime number”)  
  12. else:  
  13.    print(num,”is not a prime number”)

the fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. 

Fair use is a doctrine in the copyright law that allows limited use of copyrighted material without requiring permission from the rights holders, such as for commentary, criticism, news reporting, research, teaching or scholarship.  It provides for the legal, non-licensed citation or incorporation of copyrighted material in another author’s work under a four-factor balancing test.  The term “fair use” originated in the United States.  A similar principle, fair dealing, exists in some other common law jurisdictions.  Civil law jurisdictions have other limitations and exceptions to copyright.
