Python program that prints prime numbers in between two numbers.

This is a simple way of writing a program in Python to print prime numbers between two user-given numbers.

Breakdown of code:

First, we take the user's start and end of two boundary numbers from the user using the input() function.

start=input("Enter start value: ")
end=input("Enter end value: ")

Then we use a for loop through which we iterate through numbers between two given boundaries 

for num in range(start,end+1):

and then we use another for loop factor in range(2,num): to execute the main prime number logic, we know that the prime is nothing but the number that is only divided by itself and by 1.  

After running from 2 to num, if a break statement is not executed, it will proceed to the else case beneath the inner for loop, which prints that number.

    for factor in range(2,num):
        if(num % factor)==0:
            break
    else:
        print(num)

 From there, execution is moved to the outer loop, which increments by 1 and again checks to see if the number is prime. If there is no factor between 2 and the current number, we break the inner loop.
