Problem: Write a program in Python to print all prime numbers in an Interval.
A number is said to be Prime if it doesn’t have any factors other than 1 and itself.
Example: 3, 5, 7, etc.
To print all prime numbers in Python we have to:
- Loop through all elements in the given interval.
- Check for each number if it has any factor between 1 and itself.
- If yes then it is not prime, move to the next number.
- Else it is a Prime.
Let’s see the implementation of the same in python.
lower = int(input("Enter the lower Interval value: ")) upper = int(input("Enter the upper Interval value: ")) #loop through the Interval and check individually for num in range(lower, upper+1): #Number should not be divisible #by any number between 1-num for x in range(2,num): if num%x==0: break else: print(num)
Enter the lower Interval value: 10
Enter the upper Interval value: 20
