Python Program to Print Prime Number From 1 to N

In this tutorial, we will make 3 to 4 simple programs with the help of which we will print prime numbers from 1 to N (10, 100, 500, 1000) and also print their sum using for loop and while loop in python.

Python Program to Print Prime Number From 1 to N(10, 100, 500, 1000)

Let’s see the following program to print prime numbers from 1 to N (10, 100, 500, 1000, etc) using for loop, while loop:

• Python Program to find Prime Number using For Loop
• Python Program To Print Numbers From 1 to N Using For Loop
• Python Program To Print Numbers From 1 to N Using While Loop
• Python program to find sum of all prime numbers between 1 to n

Python Program to find Prime Number using For Loop

Python Program to Check A given Nober is Prime Or Not
 No = int(input(" Please Enter any Nober: "))
 flag = 0
 for i in range(2, (No//2 + 1)):
     if(No % i == 0):
         flag = flag + 1
         break
 if (flag == 0 and No != 1):
     print(" %d is a Prime Nober" %No)
 else:
     print(" %d is not a Prime Nober" %No)

Output

Please Enter any Number:  50
50 is not a Prime Number 

Python Program To Print Numbers From 1 to N Using For Loop

# Python Program to print n prime No using for loop

No = int(input(" Please Enter any No: "))

print("Prime Nos between", 1, "and", No, "are:")

for Nomber in range(1, No + 1):
   # all prime Nos are greater than 1
   if Nomber > 1:
       for i in range(2, Nomber):
           if (Nomber % i) == 0:
               break
       else:
           print(Nomber)

   

Output

Please Enter any Number:  25
Prime numbers between 1 and 25 are:
2 3 5 7 11 13 17 19 23 

Python Program To Print Numbers From 1 to N Using While Loop

# Python Program to print Prime NOMBERs from 1 to N

max = int(input(" Please Enter Any NOMBER: "))

NOMBER = 1

print("Prime NOMBERs between", 1, "and", max, "are:")

while(NOMBER <= max):
    Flg = 0
    i = 2

    while(i <= NOMBER//2):
        if(NOMBER % i == 0):
            Flg = Flg + 1
            break
        i = i + 1

    if (Flg == 0 and NOMBER != 1):
        print(" %d" %NOMBER, end = '  ')
    NOMBER = NOMBER  + 1a

Output

Please Enter Any Number:  15
Prime numbers between 1 and 15 are:
2   3   5   7   11   13

 

Python program to find sum of all prime numbers between 1 to n

# Python Program to print n prime No using for loop

max = int(input("Find sum of prime No upto : "))

sum = 0

for Nomber in range(2, max + 1):

    i = 2

    for i in range(2, Nomber):
        if (int(Nomber % i) == 0):
            i = Nomber
            break;

    #If the Nomberber is prime then add it.
    if i is not Nomber:
        sum += Nomber

print("\nSum of all prime No upto", max, ":", sum)

   

Output

Find sum of prime numbers upto :  25
Sum of all prime numbers upto 25 : 98   

Conclusion

Through this tutorial, we have learned how to print prime numbers and it’s sums from 1 to N using for loop, while loop in python.
