# Python Program to Display or Print Prime Numbers Between a Range or an Interval

In this program, we will learn how to display or print the Prime Numbers between a given range using the Python programming language.

I have already discussed **how to check whether a number is prime or no**t in previous posts. So, check it out for better understanding.

I will be discussing different programs

- Between an Interval.
- In Range 1 to N

### Python Programming Code to Display or Print Prime Numbers Between a Range or an Interval

In both the programs below, I have used the different approaches in the inner for loop.

In one, I have traversed until half of the number **(i/2)**. And in other, I have traversed till the square root of the number (**sqrt(i)**).

### Between an Interval

In this program, user is asked to give the start and end of the range or interval.

And then I apply the **for** loop in that range and check every number in between the range including the ends also whether they are a prime number or not.

### Code:-

start = int(input("Enter starting number of the interval : ")) end = int(input("Enter ending number of the interval : ")) print("Prime Numbers Between ", start, " and ", end, " : ") for i in range(start, end+1): isPrime = True if(i <= 1): isPrime = False else: for j in range(2, int(i/2)): if(i % j == 0): isPrime = False break if (isPrime): print(i, end=" ") print()

Enter ending number of the interval : 60

Prime Numbers Between 5 and 60 :

5 7 11 13 17 19 23 29 31 37 41 43 47 53 59

### In Range 1 to N

In this program, I have asked for only the end of the range.

And then with the help of **for** loop, numbers are checked.

### Code:-

import math end = int(input("Enter the end of the range : ")) print("Prime Numbers Between 1", " and ", end, " : ") for i in range(2, end+1): isPrime = True for j in range(2, int(math.sqrt(i)+1)): if(i % j == 0): isPrime = False break if (isPrime): print(i, end=" ") print()

### Output:-

Prime Numbers Between 1 and 25 :

2 3 5 7 11 13 17 19 23
