Python Program to Print All Prime Numbers

Q. Write a Python program to print all prime numbers between 1 and given number. Also write program to take input of two numbers and print prime numbers between them.

In our previous tutorial, you have learned to check if a number is prime number. You just need to use code inside a for loop.

Example:

A sample Python program to take input of maximum number and print all available prime numbers between 1 and given number.

max = int(input("Enter maximum number: "))  
  
for num in range(1,max + 1):  
   if num  > 1:  
       for i in range(2, num):  
           if (num % i) == 0:  
               break  
       else:  
           print(num)

max = int(input("Enter maximum number: "))

for num in range(1,max + 1):

if num > 1:

for i in range(2, num):

if (num % i) == 0:

break

else:

print(num)

Ouput:

Enter max number: 20
2
3
5
7
11
13
17
19

Another Example:

Another example to take input of minimum and maximum number. Then print all the prime numbers available between those numbers

min = int(input("Enter start number: "))  
max = int(input("Enter end number: "))  
  
for num in range(min,max + 1):  
   if num  > 1:  
       for i in range(2, num):  
           if (num % i) == 0:  
               break  
       else:  
           print(num)

min = int(input("Enter start number: "))

max = int(input("Enter end number: "))

for num in range(min,max + 1):
