Python Code to Display all prime numbers in an interval

Python Code to Display all prime numbers in an interval

In this article, we will discuss the concept of Python Code to Display all prime numbers in an interval

In this program, we are going to learn how to write the code to display all prime numbers between two intervals using different methods in Python language.

This is done using for loop and function in Python language

Display prime numbers between two intervals

Display prime numbers between two intervals using for loops

In this program, we will print prime numbers between two intervals  using a for loop in Python language

Program 1

#Get input from the user
lower=int(input("Enter a vaue for lower: "))
upper=int(input("Enter a vaue for upper: "))
for num in range(lower,upper+1):
   if num>1:  #prime numbers are greater than 1
     for i in range(2,num):
       if(num%i==0):
         break
     else:
         print(num)

When the above code is executed, it produces the following result

Enter a value for lower: 15
Enter a value for upper: 55
17
19
23
29
31
37
41
43
47
53

 

 

Display prime numbers between two intervals using function

In this program, we will print prime numbers between two intervals  using a function in Python language

Program 2

# Display prime number in given interval
#function definition for display prime
def dis_Prime(n):
    if n<2:
        return False
    for i in range(2,n):
        if n%i==0:
            return False
    return True
    
    #Reading interval value from user
max=int(input("Enter maximum value: "))
min=int(input("Enter minimum value: "))
    
print('prime numbers from %d to %d are: '%(min,max))
for i in range(min,max+1):
        if dis_Prime(i):
            print(i)

When the above code is executed, it produces the following result

Enter maximum value: 95
Enter minimum value: 5
prime numbers from 5 to 95 are:
5
7
11
13
17
19
23
29
31
37
41
43
47
53
59
61
67
71
73
79
83
89
