Finding Prime Numbers: Write code that finds and counts the number of prime numbers between 2 and 100. The output should look similar to below: 2 is prime 3 is prime 4 is not prime … … 100 is not prime There are number of primes between 2 and 100

I am writing the Python code:

count = 0    # counts number of prime numbers

def prime(n):  # method to find prime numbers between 2 and 100

   p = True  #set p to true

   for i in range(2,n):  # loop in which i ranges from 2 to n

       if (n%i == 0):  

#if n mod i is equal to 0 means if n is completely divisible by i

           p = False  # this means number is not prime so set p to false

   return p  #function returns prime numbers

for j in range(2,101):  

# loop in which j ranges from 2 to 101 to find prime and non prime #numbers in the given range

   if prime(j):  # calls prime method and checks if number is a prime

       print (j,"is prime")  # prints that number is prime

       count= count + 1  

#count variable increment every time a prime number is found

   else:  #else the number is not prime

       print(j,"is not prime ")  # prints that number is not prime

print("number of prime numbers between 2 and 100: ",count)

#displays the number of prime numbers between 2 and 100

Explanation:

The program displays the same output as given in the example of the question. It prints every prime and non prime number from 2 to 100.

The method prime() computes the prime numbers in the given range from 2 to n. This method is called to find the prime numbers from 2 to 100 and the rest of the numbers which are not prime are displayed as non prime number. count variable counts the number of prime number in the given range of 2 to 100. The program along with output is attached. The output cannot be fully shown but it is understandable. Just copy and execute the above program and you can see its output.
